AbstractSolvents are important in most industrial and domestic applications. The impact of solvent losses and emissions drives efforts to minimise them or to avoid them completely. Since the 1990s, this has become a major focus of green chemistry, giving rise to the idea of the ‘green’ solvent. This concept has generated a substantial chemical literature and has led to the development of so-called neoteric solvents. A critical overview of published material establishes that few new materials have yet found widespread use as solvents. The search for less-impacting solvents is inefficient if carried out without due regard, even at the research stage, to the particular circumstances under which solvents are to be used on the industrial scale. Wider sustainability questions, particularly the use of non-fossil sources of organic carbon in solvent manufacture, are more important than intrinsic ‘greenness’. While solvency is universal, a universal solvent, an alkahest, is an unattainable ideal.

AbstractThe polydispersity of commercially available kraft lignins (KLs) is one of the factors limiting their applications in polymer-based materials. A prerequisite is thus to develop lignin fractionation strategies compatible with industrial requirements and restrictions. For this purpose, a solvent-based lignin fractionation technique has been addressed. The partial solubility of KL in common industrial solvents compliant with the requirements of sustainable chemistry was studied, and the results were discussed in relation to Hansen solubility parameters. Based on this screening, a solvent sequence is proposed, which is able to separate well-defined KL fractions with low polydispersity.

In situ product recovery (ISPR), in the form of an extractive fermentation process, can increase productivity and product titers in the sustainable production of platform chemicals. To establish a guideline for the development of industrially relevant production processes for such bio-based compounds, a wide screening was performed, mapping the potential of an extensive range of solvents and solvent mixtures. Besides solvent biocompatibility with Saccharomyces cerevisiae, distribution coefficients of three organic acids (protocatechuic acid, adipic acid and para-aminobenzoic acid) and four fragrance compounds (2-phenylethanol, geraniol, trans-cinnamaldehyde and β-ionone) were determined. While for highly hydrophobic fragrance compounds, multiple pure solvents were identified that were able to extract more than 98%, reactive extraction mixtures were proven effective for more challenging compounds including organic acids and hydrophilic alcohols. For example, a reactive mixture consisting of 12.5% of the extractant CYTOP 503 in canola oil was found to be biocompatible and showed superior extraction efficiency for the challenging compounds as compared to any biocompatible single solvent. This mapping of biocompatible solvents and solvent mixtures for the extraction of various classes of industrial platform chemicals can be a tremendous step forward in the development of extractive fermentations.

Chemical absorption is widely regarded as the most promising technology for post-combustion CO2 capture from large industrial emission sources with CO2 separation from natural gas using aqueous amine solvent system having been applied since the 1930s. The use of monoethanolamine (MEA) in CO2 absorption system possesses several drawbacks, such as high regeneration energy, high solvent loss, and high corrosion tendency. Various solvents have been developed for post-combustion CO2 capture application including the development of aqueous solvents and phase-change solvents. Some of these alternate solvents have been reported to have better solvent properties, which could improve the CO2 absorption system performance. This paper reviews key parameters involved in the design improvement of several chemical absorption process systems. In addition, some novel solvent systems are also discussed, for example encapsulated solvents systems. Some of the key solvent parameters that affect the capture performance, such as heat of reaction, absorption rate, solvent working capacity, solvent concentration, and solvent stability, are discussed in this paper, particularly in relation to the economic viability of the capture process. In addition, some guidelines for the future solvent development are discussed.

Annotation:
Lipases are a group of enzymes naturally endowed with the property of performing reactions in aqueous as well as organic solvents. The esterification reactions using lipase(s) could be performed in water-restricted organic media as organic solvent(s) not only improve(s) the solubility of substrate and reactant in reaction mixture but also permit(s) the reaction in the reverse direction, and often it is easy to recover the product in organic phase in two-phase equilibrium systems. The use of organic solvent tolerant lipase in organic media has exhibited many advantages: increased activity and stability, regiospecificity and stereoselectivity, higher solubility of substrate, ease of products recovery, and ability to shift the reaction equilibrium toward synthetic direction. Therefore the search for organic solvent tolerant enzymes has been an extensive area of research. A variety of fatty acid esters are now being produced commercially using immobilized lipase in nonaqueous solvents. This review describes the organic tolerance and industrial application of lipases. The main emphasis is to study the nature of organic solvent tolerant lipases. Also, the potential industrial applications that make lipases the biocatalysts of choice for the present and future have been presented.

The aim: implementation of the principles of green chemistry by regenerating the synthesis solvent 1,2,4-trichlorobenzene and reusing it during the synthesis of the Naphazoline nitrate substance. Study of the influence of the regenerated solvent on the quality of the final product by controlling analytical quality parameters. Development of a method for the quantitative determination and validation of synthesis solvents in a substance. Materials and methods: samples of the substance were synthesized according to the optimized proprietary technology of Farmak JSC. The obtained batches of fresh and regenerated 1,2,4-trichlorobenzene were analyzed according to the monograph of the European Pharmacopoeia on Naphazoline nitrate 0147. Results: the possibility of using regenerated 1,2,4-trichlorobenzene for the synthesis of the substance Naphazoline nitrate has been proven. It is shown that the regenerated solvent does not have a negative effect on the profile of impurities and the polymorphic form of the substance. Analytical quality parameters met the requirements of the internal specification and the requirements of the European Pharmacopoeia monograph. The developed and validated method of quantitative determination of synthesis solvents makes it possible to determine them at the required level. Conclusions: the introduction of regenerated 1,2,4-trichlorobenzene into the synthesis scheme made it possible to significantly reduce the amount of waste per 1 kg of product, which in turn significantly reduced the negative impact on the environment. Analytical quality parameters for regenerated 1,2,4-trichlorobenzene meet the requirements of the internal specification. Industrial series obtained on the regenerated solvent meet the requirements of the monograph of the European Pharmacopoeia. The polymorphic form of the substance batches manufactured on regenerated 1,2,4-trichlorobenzene corresponds to the polymorphic form of the substance batches manufactured on the fresh solvent. The obtained results on the influence of the regenerated solvent on the profile of impurities in the finished substance show the similarity of the profile of the series manufactured on both solvents. According to the requirements of ICH Q3C Impurities: Guideline for residual solvents, a method for quantitative determination of the residual content of 1,2,4-trichlorobenzene in the final product by gas chromatography was developed and validated. The absence of synthesis solvents at the limit of detection is shown

Abstract The sustainable production of solvents from above ground carbon is highly desired. Several clostridia naturally produce solvents and use a variety of renewable and waste-derived substrates such as lignocellulosic biomass and gas mixtures containing H2/CO2 or CO. To enable economically viable production of solvents and biofuels such as ethanol and butanol, the high productivity of continuous bioprocesses is needed. While the first industrial-scale gas fermentation facility operates continuously, the acetone–butanol–ethanol (ABE) fermentation is traditionally operated in batch mode. This review highlights the benefits of continuous bioprocessing for solvent production and underlines the progress made towards its establishment. Based on metabolic capabilities of solvent producing clostridia, we discuss recent advances in systems-level understanding and genome engineering. On the process side, we focus on innovative fermentation methods and integrated product recovery to overcome the limitations of the classical one-stage chemostat and give an overview of the current industrial bioproduction of solvents.

The effects on birch outer bark (BOB) ethanolic extractives’ chemical composition after recrystallization with C2–C5 alkanols were studied in this paper. Ethanol, 1-propanol, 2-propanol, 1-butanol, 2-butanol, and 1-pentanol were used as solvents. The solubility of BOB extractives at the solvents boiling point was determined empirically. It was found that, with an increase of the boiling point of the solvents, the solubility of the extractives increased, reaching up to 486 g/L in 1pentanol at 142.2 °C. Recrystallization yields reached up to 67 wt% using 2-butanol and the purity of betulin up to 96 wt% using 2‐propanol as a solvent. Considering the yield of recrystallization, betulin content, boiling point of the solvent, solvent loss, toxicity and eco-friendliness of the solvent, ethanol was chosen to be the most suitable solvent for industrial scale purification of betulin in the BOB extractives. Using only one recrystallization step the content of betulin was increased by 20% — from 75 to 95 wt% and the yield of recrystallization was 32.1 g per liter of solvent.

This is a knowledge contribution to the unsatisfactory biodegradation problem, when biotrickling filters are purifying mixed paint solvents. A biotrickling filter manufacturer reported low biodegradation rates during the purification of a hydrocarbon pollutant mix from an industrial paint spraying floor. From a gas chromatograph/mass spectrometer analysis both hydrophilic and hydrophobic solvents were found in the polluted air. It is known that biodegradation is retarded, if the pollutant does not transfer from gas to liquid into the biofilm and it was therefore suspected that hydrophobic pollutants do not sufficiently migrate into the water/biofilm. To test this hypothesis, pure, rather than mixed pollutants, were injected into the abiotic biotrickling filter. When hydrophobic paint solvent (xylene) was sprayed into the biotrickling filter, the solvent load at the outlet of the filter was almost as high as at the inlet. But when pure, hydrophilic paint solvent (PGME) was sprayed into the abiotic biotrickling filter, the solvent load measured at the outlet of the filter was zero, indicating complete dissolution into the circulation water. Carbon/solvent loads at the filter outlet and inlet were measured with a portable flame ionization detector instrument. The experiment confirms that the hydrophobic solvent does not migrate into the liquid phase. This poor mass transfer of hydrophobic solvents is likely to be the reason for the low biodegradation rate. The result is highly relevant to the paint spraying industry and manufacturers of exhaust gas treatment equipment alike, who spend millions in non-sustainable incineration of exhaust gases.

In recent years, almost all extraction processes in the perfume, cosmetic, pharmaceutical, food ingredients, nutraceuticals, biofuel and fine chemical industries rely massively on solvents, the majority of which have petroleum origins. The intricate processing steps involved in the industrial extraction cycle makes it increasingly difficult to predict the overall environmental impact; despite the tremendous energy consumption and the substantial usage of solvents, often the yields are indicated in decimals. The ideal alternative solvents suitable for green extraction should have high solvency, high flash points with low toxicity and low environmental impacts, be easily biodegradable, obtained from renewable (non-petrochemical) resources at a reasonable price and should be easy to recycle without any deleterious effect to the environment. Finding the perfect solvent that meets all the aforementioned requirements is a challenging task, thus the decision for the optimum solvent will always be a compromise depending on the process, the plant and the target molecules. The objective of this comprehensive review is to furnish a vivid picture of current knowledge on alternative, green solvents used in laboratories and industries alike for the extraction of natural products focusing on original methods, innovation, protocols, and development of safe products.

A recent chemical spill of 4-Methylcyclohexanemethanol (4-MCHM) in West Virginia left 300,000 people without water. Officials claimed that this compound is not lethally toxic, but potentially harmful if swallowed or inhaled, and can cause eye and skin irritation. Sittig's Handbook of Toxic and Hazardous Chemical Carcinogens reports high exposures from skin contact or inhalation may cause damage to the heart, liver, kidneys, and lungs, and may result in death. However, no quantitative data seem to exist and no references can be found on neurotoxicity. We have investigated the neurotoxicity of 4-MCHM using mammalian nerve cell networks grown on microelectrode arrays. Network spontaneous activity from multiple units (range 48 – 120 per network) were used as the primary readout. Individual units were followed based on spike waveforms digitized at 40 kHz (Plexon MNAP system). Dose response curves show the effective inhibitory concentration at 50 percent decrease (EC50) to average 27.4 microM SD±6.17. However, in the presence of 40 microM bicuculline, a competitive GABAA antagonist, the EC50 shifts to 70.63uM SD ±4.3; implying that early, low concentration exposures to 4-MCHM involve GABA activation. Initial activity loss occurs without active unit loss (defined as 10 or more template threshold crossing per min), indicating functional interference with spike production. Full recovery has not been seen at concentrations above 130 microM, unless the culture was given bicuculline. Direct exposure to 400uM results in immediate, irreversible loss of spike production, followed by necrosis of glia and neurons.

Neste estudo, o aluminato de zinco foi sintetizado através da reação de combustão e caracterizado de acordo com suas propriedades físicas e texturais. O catalisador foi utilizado na reação de transesterificação em condições subcríticas e supercríticas, via rotas metílica e etílica a partir de óleos e gorduras residuais (OGR). As condições experimentais utilizadas foram previamente estudadas através do acervo bibliográfico e fixadas em 2 horas de reação, razão molar de álcool:óleo 40:1, agitação mecânica de 700 rpm, razão de catalisador em peso com relação à quantidade inicial de óleo entre 1 e 10 % e temperatura de reação entre 60 e 200 ºC. O estudo da reação de transesterificação indicou resultados promissores para as duas metodologias utilizadas. Os resultados obtidos indicaram que o rendimento em ésteres aumentou significativamente em temperaturas amênas quando a razão de catalisador:óleo foi acrescida de 1 % para 5,5 % e 10 % de catalisador em relação à quantidade inicial de óleo para as duas metodologias avaliadas. Estes dados foram justificados pela possibilidade de formação de mais do que uma fase entre o óleo e o álcool em baixas temperaturas. Contudo, a influência desta razão decresceu à medida que se aumentou a temperatura de reação até 200 °C, sendo obtidos rendimentos em ésteres > 98 % em 30 minutos de reação em condições severas utilizando-se 1 % de catalisador e dióxido de carbono em estado supercrítico.
In this study, the zinc aluminate was synthesized by the combustion reaction and characterized according to their physical and textural properties. The catalyst was used in the transesterification reaction in supercritical and subcritical conditions, via methylic and ethylic routes from waste frying oils (WFO). The experimental conditions used were previously studied and fixed in 2 hours of reaction time, 40:1 of alcohol:oil molar ratio, 700 rpm of mechanical stirring, 1, 5.5 % and 10 % by weight of catalyst ratio and 60 to 200 º C of reaction temperature. The study of the transesterification reaction indicated promising results for both methodologies. The results indicated that the yield of esters at moderate temperatures significantly increased when the ratio of catalyst:oil was increased from 1 % to 5.5 % and 10 % of catalyst relative to the initial quantity of oil to the two methodologies evaluated. These data were substantiated by the possibility of forming more than one phase between the oil and the alcohol at low temperatures. However, the influence of this ratio is decreased as the reaction temperature increased to 200 ° C, were obtained > 98% of esters yields in 30 minutes of reaction under stringent conditions using 1 % catalyst and supercritical carbon dioxide.

Annotation:
The aim of this work was to devise and investigate a solvent extraction system for rhodium, from aqueous chloride solutions, having potential industrial applicability. The extractant investigated was Kelex 100, a commercially available derivative of 8-hydroxyquinoline. Ultimately, two different systems were developed. Both are based on an initial complexation reaction between the aqueous rhodium chloride complexes, (RhCl$ rm sb{6-n}(H sb2O) sb{n} rbrack sp{(3-n)-}$ and stannous chloride, referred to as the activation stage, but the two systems use a different Sn:Rh molar ratio. In both cases, the Rh-Sn complexes, either (Rh(SnCl$ sb3) sb5 rbrack sp{4-}$ or (RhCl$ rm sb3(SnCl sb3) sb3 rbrack sp{3-},$ respond well to extraction with Kelex 100. One of the main differences between the two systems is in the stripping medium which is used to transfer the rhodium from the loaded organic phase back into an aqueous phase. In the case of the high Sn:Rh ratio feeds, the stripping stage is based on sulfuric acid, whereas in the case of low Sn:Rh ratio feeds, the rhodium is stripped from the organic phase using a sulfite containing hydrochloric acid solution.
The two systems were characterized in terms of their equilibrium and kinetic behaviour during all three stages; activation, extraction, and stripping. Activation was found to proceed either at room temperature or at elevated temperatures and the above-mentioned expected Rh-Sn complexes were identified through $ sp{119}$Sn NMR and Raman spectroscopy. The extraction stage was found to be quantitative for rhodium and it was also found to be very rapid, with contact times of less than five minutes sufficient for rhodium extraction. The extraction mechanism was determined to be ion-pair formation with the protonated Kelex 100 molecules at a stoichiometry such that the overall charge in the organic phase is neutral, i.e., three Kelex 100 molecules for (RhCl$ rm sb3(SnCl sb3) sb3 rbrack sp{3-}$ and four for (Rh(SnCl$ sb3) sb5 rbrack sp{4-}.$
The stripping stages were the most problematic for both systems. In one case, the system was eventually abandoned due to limitations in the amount of rhodium which could be transferred to the sulfuric acid strip solution. For the low Sn:Rh system, reasonable rhodium transfer and concentration level were obtained. The rhodium complex in the strip solution has been proposed to be (RhCl$ rm sb2(SO sb3) rbrack sp{3-}.$ Strip solutions up to $4 times10 sp{-2}$M in rhodium concentration have been produced, from initial feed solutions having a rhodium concentration of about $4 times10 sp{-3}$M. Preliminary flowsheets are proposed for further refinement for both systems, although only the second system, the low Sn:Rh ratio system which uses sulfite stripping, is advocated for further development.

Essa abordagem é feita comparando-se resultados propiciados por alguns autores da área com dados da área com dados levantados de uma empresa no Brasil em dois períodos distintos, incluindo análise de evolução da planta, onde a alta gerência monitora a produtividade e a qualidade dos produtos, e trata as perdas no ambiente de transformação como consumo de solvente utilizado para extração do óleo de soja e consumo de combustível para a geração de energia térmica. Conclui-se que a indústria de extração de óleo vegetal, possui diversas variáveis de controle pelo conjunto de operações necessárias à transformação, ressaltando neste caso a perda de energia térmica como prioridade de atitudes de melhorias. Dado que a tendência de aumento da capacidade de processamento de soja é evidente, pela perspectiva de crescimento da produção de soja no Brasil, deve ser considerado neste contexto, o investimento em conhecimento para as pessoas exercerem as atividades operacionais em perfeita sincronia com as informações que ocorrem no processo, garantindo o objetivo da organização de minimização das perdas, e consequente aumento do lucro e crescimento

This approach is made comparing the results obtained by some authors in the field with data collected from a company in Brazil in two distinct periods, including examination of the plant, where top management monitors productivity and product quality, and treats losses the environment of use as processing solvent used to extract the soybean oil and fuel to generate heat energy. It is concluded that the industry of oil extraction plant has several control variables the operations required for processing, emphasizing in this case the loss of thermal energy as priority actions for improvements. Since the trend of increased processing capacity of soybean is evident from the perspective of growth of soybean production in Brazil, should be considered in this context, investment in knowledge for people to exercise operational activities in perfect synchrony with the information occur in the process, ensuring the organization's goal of minimizind losses, and consequent increase in profit and growth

Dado que a tendência de aumento da capacidade de processamento de soja é evidente, pela perspectiva de crescimento da produção de soja no Brasil, deve ser considerado neste contexto, o investimento em conhecimento para as pessoas exercerem as atividades operacionais em perfeita sincronia com as informações que ocorrem no processo, garantindo o objetivo da organização de minimização das perdas, e consequente aumento do lucro e crescimento
Abstract: The activities of the industry with a continuous production system have their own characteristics depending on the process that is willing to turn a raw material, so this work is to analyzed the losses in the continuous production of soybean oil extraction solvent, presenting the description of the process and key performance indicators and propose suggestions for the improvement of monitoring results. This approach is made comparing the results obtained by some authors in the field with data collected from a company in Brazil in two distinct periods, including examination of the plant, where top management monitors productivity and product quality, and treats losses the environment of use as processing solvent used to extract the soybean oil and fuel to generate heat energy. It is concluded that the industry of oil extraction plant has several control variables the operations required for processing, emphasizing in this case the loss of thermal energy as priority actions for improvements. Since the trend of increased processing capacity of soybean is evident from the perspective of growth of soybean production in Brazil, should be considered in this context, investment in knowledge for people to exercise operational activities in perfect synchrony with the information occur in the process, ensuring the organization's goal of minimizind losses, and consequent increase in profit and growth

AbstractProof production for SMT solvers is paramount to ensure their correctness independently from implementations, which are often prohibitively difficult to verify. Historically, however, SMT proof production has struggled with performance and coverage issues, resulting in the disabling of many crucial solving techniques and in coarse-grained (and thus hard to check) proofs. We present a flexible proof-production architecture designed to handle the complexity of versatile, industrial-strength SMT solvers and show how we leverage it to produce detailed proofs, including for components previously unsupported by any solver. The architecture allows proofs to be produced modularly, lazily, and with numerous safeguards for correctness. This architecture has been implemented in the state-of-the-art SMT solver cvc5. We evaluate its proofs for SMT-LIB benchmarks and show that the new architecture produces better coverage than previous approaches, has acceptable performance overhead, and supports detailed proofs for most solving components.

AbstractNP-hard combinatorial optimization problems are pivotal in science and business. There exists a variety of approaches for solving such problems, but for problems with complex constraints and objective functions, local search algorithms scale the best. Such algorithms usually assume that finding a non-optimal solution with no other requirements is easy. However, what if it is NP-hard? In such case, a SAT solver can be used for finding the initial solution, but how can one continue solving the optimization problem? We offer a generic methodology, called Local Search with SAT Oracle (), to solve such problems. facilitates implementation of advanced local search methods, such as variable neighbourhood search, hill climbing and iterated local search, while using a SAT solver as an oracle. We have successfully applied our approach to solve a critical industrial problem of cell placement and productized our solution at Intel.

Abstract Objectives/Scope This paper describes operational feedback from one of our Acid Gas Removal Units (AGRUs), that operates an amine-based solvent technology, in the case of high H2S content in the sour gas (20 mol%). We show that the acidification of the solvent results in energy savings and a reduction of GHG emissions. Methods, Procedures, Process This paper focuses on the benefits of solvent acidification in an AGRU. In practice, the solvent acidification leads to a salting-out effect and lower residual acid gas content in the lean amine, allowing the optimization of the specific reboiler duty. The approach requires a regular solvent monitoring to quantify the solvent acidity and the residual amount of acid gases in the lean amine, and the evolution of the solvent degradation products over time. Indeed, the degradation products from amine oxidation are acidic components and excessive stripping may sometimes result in corrosion- and fouling-related operational issues. This shall be supported with modelling the salting out effect. Results, Observations, Conclusions In our case, we observe a continuous build-up of heat stable salts in the amine-based solvent, which come from the degradation of amine solvent after oxidant ingress. This induced a reduction of the H2S residual content from 500 ppmw to less than 50 ppmw. This allowed the optimization of the AGRU specific reboiler duty of about 20% energy savings (down to 80 kg 4 barg steam / m3 solvent), which leads to 10% reduction in GHG emissions. However, this salts build-up also generates operational issues such as higher corrosion rate of carbon steel equipment and fouling issues due to iron sulphates and carbonates deposits. Thus, this paper will present the trade-off found between energy savings and unit operability, based on our industrial feedback considering the "natural" acidification of the solvent. The modelling of the vapour-liquid equilibrium of the altered solvent is a must for unit optimization, considering the impact of acidic components coming from solvent degradation or components added on purpose to improve the solvent regeneration. This concept is currently already implemented in industrial sites, especially in low pressure units such as Tail Gas Treatment Units (TGTUs), to respect specifications on Sulphur compound emissions to the atmosphere. Novel/Additive Information This paper will present a solvent monitoring novel strategy to optimize the amount of steam required in the reboiler of the regeneration section without impairing the unit operability.

An innovative technology for the continuous extraction of bioactive compounds from a wide range of biological materials has been developed, scaled up and successfully demonstrated at commercially-relevant scales. The technology, known as MAPTM, or “Microwave-Assisted Process”, robustly transfers from laboratory to continuous, industrial scale operation. In wide-ranging trials, MAPTM has comprehensively demonstrated its ability to outperform many KPIs of conventional extraction processes, while offering biomass throughput, product consistency and low operational costs not attainable by other emerging technologies. Radient’s proprietary continuous-flow MAPTM extractor, Figure 1, was designed for continuous processing of up to 200 kg/h of biomass material. Verification of the mechanical integrity of the system was confirmed by flow testing of biomass / solvent slurries. Testing and verification of the efficiency of microwave energy transfer to the extractor cavity was completed at various microwave power settings using flowing water at 870 kg/h. The microwave energy transfer to the system was verified to be >95 % in each case. As an example of performance, continuous flow MAPTM extraction of the antioxidant SDG from flax biomass was performed using 70 % ethanol / water as the solvent at two different conditions: - 75 kg/h flax / 5 L/kg solvent / 15 kW microwave power / extractor residence time 24 min; - 110 kg/h flax / 5 L/kg solvent / 20 kW microwave power / extractor residence time 16 min. The industrial-scale conditions for these runs were determined by extrapolating from optimized conditions previously obtained from batch lab-scale MAPTM experiments. The continuous flow approach eliminates the requirement for having geometric similarity between scales, i.e the equipment shape and dimensions do not have to scale proportionately.

Membrane separation technology has been receiving much attention for processing vegetable oils due to its potential advantages over conventional purification techniques. Based on the molecular weights and their interactions with the membrane, various solutes can be removed or purified using this technology. However, one of the major challenges is that the membrane has to be chemically inert to organic solvents such as hexane or acetone. Thus, many studies have been focused on developing chemically resistant membranes for specific industrial applications. Organic solvent nanofiltration (OSN) membranes is one of the potential energy efficient and sustainable separation processes that can drastically change the way solvents are recovered and free fatty acids (FFA) are removed in the vegetable oil industry. Seppure's patented GreenMem Series can process vegetable oil in acetone and hexane, achieving high product purity at relatively mild conditions (25 €“ 60°C, 10 €“ 30 bar). This results in up to 90% lower energy consumption and CO2e emissions as well as up to 30-50% lower operating costs compared to the conventional separation processes. GreenMem Series membranes show a high pure solvent flux of 30 €“ 40 LMH for acetone and hexane as well as high rejection towards oil molecules >95%. Moreover, 99% of FFA can be removed from a solvent/FFA mixture using multi-pass filtration system, which can be implemented in a unique membrane system to separate oil/FFA/solvent from each other. Moreover, GreenMem system can be implemented in both continuous and batch processes. Just like many other membrane technologies, its modularity makes it easy to be scaled up based on production capacity to augment existing processes. It is envisioned that OSN technology provides both positive economic and environmental impacts on the vegetable oil industry.

Annotation:
El almidón es un biopolímero, biodegradable, biocompostable y biobasado, excelente candidato para ser usado como reemplazo de los materiales plásticos convencionales, de origen petroquímico. Sin embargo, su producción a nivel industrial presenta varios retos tecnológicos, dado que se debe entender su comportamiento químico para poder realizar una formulación con los demás ingredientes, que le permitan plastificarse adecuadamente. Esto es, que las cadenas de almidón se desorganicen de la compacta estructura en la que las organiza la naturaleza (ej. almidón de yuca en polvo), el cual si se calienta se degrada y quema. Se debe agregar un solvente y/o plastificante para que las moléculas del almidón se solubilicen, y poder así obtener una mezcla termoplástica. Una de las principales técnicas para el procesamiento de polímeros es la extrusión, ya que es la más conocida, estudiada y económica, y ayudaría a acelerar el cambio a materiales más sostenibles, ya que muchas compañías no utilizan biopolímeros en sus productos porque deberían cambiar toda la maquinaria de la línea de producción si aplican otras nuevas técnicas asociadas con los nuevos biopolímeros. Por ejemplo, una correcta plastificación del almidón se logra usualmente al disolverlo y calentarlo en agua (ej. preparación de maizena), y dicha solución puede agregarse en un recipiente (técnica de moldeo por solvente), pero requiriendo altos tiempos de secado (1-2 días). También se puede aplicar la solución, a través de una boquilla, sobre una cinta que se mueve a una velocidad constante en un túnel de calentamiento, buscando la producción y el secado continuo de una película de almidón termoplástico (técnica de tape casting), pero esta técnica está en evaluación y aún no se usa en la industria de polímeros en la actualidad. Así, el reto tecnológico de este proyecto consiste, en una primera etapa, en encontrar una formulación apropiada para la plastificación correcta del TPS, pero utilizando una máquina de extrusión; en cuyo caso se debe reducir al máximo la adición de agua (ya que ésta generaría vapores indeseados en la máquina). Con base en dicha formulación, se busca producir mezcladores de bebidas y pitillos a partir de la extrusión, determinando las bases del proceso productivo, al igual que desarrollando una evaluación económica del proceso para conocer su viabilidad a nivel industrial. Este proyecto se presenta bajo el grupo de investigación GEA de la ETITC, y su nueva línea de investigación en biopolímeros, y busca ser un primer paso en el desarrollo de la línea de transformación de polímeros en la escuela. Además, este proyecto pretende poder servir de apoyo, e igualmente retroalimentarse del semillero Biopolymers, que se espera su apertura en el 2022-II. Y de igual forma, la expectativa de este proyecto es aumentar la capacidad tecnológica y la formación de recurso humano en la escuela, a través de la dirección de una tesis de pregrado en Ingeniería de Procesos Industriales; al igual que ofrecer a los estudiantes opciones de desarrollo que puedan abarcar desde proyectos de aula y proyectos integradores, hasta emprendimientos o proyectos de vida para nuestros profesionales.

Devlin, Robert. Towards Good Governance of Public-Private Alliance Councils Supporting Industrial Policies in Latin America. Inter-American Development Bank, März 2014. http://dx.doi.org/10.18235/0010576.

Der volle Inhalt der Quelle
Annotation:
Systematic application of industrial policies has reemerged in Latin America after a hiatus during the era of the Washington Consensus. These industrial policies are broadly different from the past. One of the characteristics of the region's new industrial policies is the use of public-private alliance councils (PPAs) to help guide their development and implementation. The deployment of public-private dialogue and related problem solving is considered an essential component of modern industrial policies. However, to be effective councils must be well governed. This paper approaches the issue of governance of PPAs with an overview of their rationale and framework, and then draws from the experience of several OECD countries, most of which have long experience working with councils, to illustrate how they operate and gain insights on good governance for Latin America alliances. The paper examines the intangible dimensions of governance, as well as tangibles involving the structure and procedures of councils.

Annotation:
In recent years, there has been renewed interest in the use of industrial polices. The need for modern industrial policies has been increasingly acknowledged in the literature and by the praxis of developed and developing countries, including much of Latin America. Whether a country should have an industrial policy is no longer in question; rather, the issue is how to do it right. Nevertheless, research is still incipient on the experience with the specific institutional arrangements and governance structure required for effective modern industrial policy and the form that such institutions should take. This is especially true in large countries with developed subnational governance structures. One institutional mechanism considered vital to effective modern industrial policy is the modality of public-private dialogue and problem solving that supports a search for obstacles and solutions to agreed development objectives. This paper addresses industrial policy in general, but especially at the subnational level, with new empirical evidence from a large federal state: Mexico. It presents a detailed analysis of the governance of 32 newly created public-private State Productivity Commissions (Comisiones Estatales de Productividad, or CEPs). The analysis also is informed by new research on the longer experience of subnational public-private councils in Colombia's national system of competitiveness and innovation.

This is the first volume of the concurring series of Reports in Applied Mechanics, which is based on the outcome of the advanced project course TMPM07 in Applied Mechanics at Link¨oping University during the autumn of 2022. The course lay-up is based on several industrial related projects within the field of Solid Mechanics, concerning fatigue, topology optimisation, structural dimensioning, contacts etc, and Fluid Mechanics, concerning fluid dynamics, flow, aerodynamics, heat transfer etc. The students tackle industry relevant projects in close collaboration with industry from near and neighbouring regions and work in project groups to solve the given tasks within the time limit of the course. Close collaboration with the industry is necessary to define planning, update and feedback for further evaluation at the industry. Three projects were performed during the course of 2022, two within Solid Mechanics and one in Fluid Mechanics. The projects were all performed in tight collaboration with industry partners, and had a close application to real industrial problems. A good opportunity for the students to show-off all their gained knowledge and apply in the best possible way to make innovative solutions in the respective projects. Something they all managed to do with success!

The realities of digitalization require changes in strategies for choosing educational technologies. The modern educational process is not possible without the use of digital technologies. Digital technologies have led to the arising and development of blended learning. However, its effectiveness is determined not only by technology. The human factor receives special attention in this direction. Analysis of the World Development Report 2016: Digital Dividends allows us to identify digital competence as a necessary condition for the successful use of digital technologies, and hence blended learning. Learning interactions designing in the process of implementing blended learning requires timely diagnosis of the level of digital competence. A popular tool for this is the Digital Competence Framework for Citizens. To clarify the peculiarities of its use was made an analysis of the experimental implementation results of blended learning in the industrial training in sewing for intended masters. During the research, it was revealed that the most important digital competence areas for the variable learning establishment in the training of future professionals are Information and data literacy, Communication and collaboration and Problem solving. In addition, competence for area Problem solving conduce to increase the level of competence for all other areas. The level of digital competence of the subjects mainly coincide to the characteristics of basic and secondary levels. The obtained data clarified the reasons for the difficulties, decrease motivation and cognitive activity that occur among students using distance courses-resources learning designed for blended learning. Thus, the use of the Digital Competence Framework for Citizens at the initial stage of implementing blended learning can make a rational choice of strategies for combining face-to-face and distance learning technologies.
