Abstract:
According to current estimates, industrial effluent discharge has contaminated around one-third of INDIA’s water, solid waste, and other hazardous waste.The bulk of these defaulting industries are petrochemicals, sugar mills, distilleries, leather processing industries, paper mills, agrochemical and pesticide manufacturing sectors, and pharmaceutical businesses.For these industries, surface water is the major waste disposal method.Untreated or ostensibly treated effluents have raised the quantity of surface water pollution by up to 20 times the acceptable limit in 22 seriously polluted locations throughout the world. Almost all water bodies in INDIAwas found to be contaminated by industrial activity. Although the strict guidelines of the Central Pollution Control Board(CPCB) apply to all industries in India, the current state of the environment is far from ideal.

Abstract:
To ensure competitiveness in world markets in the context of deepening globalization processes, Ukraine needs to adjust its own raw material base, which will qualitatively change the structure of Ukrainian exports from raw materials to goods with a high share of value added. The purpose of the article is to assess the development capacity of chemical, textile, agro-processing, and woodworking industries of Ukraine on the basis of import substitution and export orientation and substantiation of organizational and economic forms of its practical implementation. The author’s interpretation of the term “capacity of industrial system development” is offered. Based on the results of the technological profile analysis, the level of capacity utilization and performance indicators of the largest chemical enterprises of Ukraine, and strategic guidelines for the development of promising chemical industries are substantiated and organizational and economic forms of realizing their capacity are suggested, in particular in the Western region. Proposals for ensuring competitive conditions for participants in the domestic market of light industry products are provided, the need for simplified regulatory procedures and investment incentives to ensure the development of domestic light industry enterprises is substantiated. An organizational mechanism for restoring the raw material base of textile and other industries is developed. The regions of Ukraine are grouped according to the capacity of timber harvesting and industrial processing. The perspective directions of development of the woodworking industry in the Western region (in the context of productions) are defined and the basic strategies of their realization focused on the internal and external markets of production are outlined. The organizational forms of realization of the development capacity of agro-processing productions in Ukraine and mechanisms of their institutional support are offered.

Abstract:
Indonesia is rich in diversity of agroindustrial products. Yet the tropical climate causes agroindustrial products being easily damaged. Techniques for food preservation have been widely known such as drying, cooling or freezing, canning, chemical use and others. To complement these techniques, a promising unconservative technique using ionizing radiation can be safely used to preserve food, without leaving residual radiation or hazardous chemical residues. Unfortunately in Indonesia, the irradiation technique was still not common since few industries have used this technique. Compared to the neighbouring countries, only Indonesia as a big country had no interest in developing irradiator technology. To introduce this technique to the public, especially investors, BATAN in 2017 built a pilot project named as Iradiator Gamma Merah Putih (IGMP). It was designed with maximum activity up to 2 MCi using Cobalt-60 as radioactive sources and can serve from low to high dose. By the time, the number of agroindustrial customers, as well as their quantity to be processed, are increasing. The irradiation technique becomes an appropriate technology for Indonesian agroindustries. It is then necessary to build gamma irradiation facilities in areas that have large agricultural yields. This way can minimalize crop losses and increase the quality of the agricultural products.

AbstractThe objective of the research presented in this Research Communication was to access the environmental impact of the Latvian dairy industries. Site visits and interviews at Latvian dairy processing companies were done in order to collect site-specific data. This includes the turnover of the dairy industries, production, quality of water in various industrial processes, the flow and capacity of the sewage including their characteristic, existing practices and measures for wastewater management. The results showed that dairy industries in Latvia generated in total approximately 2263 × 103 m3 wastewater in the year 2019. The Latvian dairy effluents were characterized with high chemical oxygen demand (COD), biological oxygen demand (BOD) and total solids (TS). Few dairy plants had pre-treatment facilities for removal of contaminants, and many lacked onsite treatment technologies. Most facilities discharged dairy wastewater to municipal wastewater treatment plants. The current study gives insight into the Latvian dairy industries, their effluent management and pollution at Gulf of Riga due to wastewater discharge.

Abstract:
Raw wool fibers contain fat, suint, plant material and minerals. It is necessary to remove these from wool by scouring with a combination of detergents, wetting agents and emulsifiers before further processing. Dyeing and finishing of wool fibers is necessary for their application in apparel and also in interior, automotive, smart and technical textiles. Some of the detergents and auxiliaries used in scouring are eco-toxic and some of them are endocrine disruptors. In many countries, wool scouring and dyeing effluents cannot be discharged to watercourses without further treatment by removing color and toxic components. Wool fibers can be given chemical treatments to make them stain-resistant, flame retardant, shrink-resistant, photo-stable and resistant to insect attack. Some of the chemicals under current practice to achieve these functionalities in wool are not eco-friendly and their discharge to water course is limited to the consent limit set by environment agencies. Environmental impact assessment of raw wool production is well studied but to our knowledge no comprehensive study has been carried out around the environmental impact of chemical processing of wool. Like those of other fiber types, the wool textile industries are under intense consumer as well as stakeholder scrutiny. Accreditation schemes now exist to provide reassurance to modern consumers, who want to see that not only are the marketed products safe but also that they are processed sustainably under ethically and environmentally acceptable conditions. Several alternatives to improve the environmental credentials of various chemical processes used for wool will be discussed.

Abstract:
A unique problem in the continuous processing industries (CPI), arising from integration of statistical process control (SPC) with automatic process control (APC), is choosing the correct variable(s) for process monitoring. It was shown that the manipulated variable displayed superior process monitoring potential for first-order processes with moderate amounts of inertia, subject to an ARMA(1,1) disturbance when the autoregressive parameter, $\phi$, is larger than the moving average parameter, $\theta$. It was also shown for large amounts of process inertia that the reconstructed output (disturbance) was the most effective charting variable ($\phi > \theta$). However, when $\theta$ exceeds $\phi$ the residual chart performed the best. In some very severe cases, process observations are so highly correlated that they display a wandering mean. Such nonstationary disturbances are extremely problematic in the CPI. The n$\sp{\rm th}$-difference chart developed in this work, proved to be efficient at identifying the presence of assignable cause in first-order processes under Minimum Variance feedback control when subjected to IMA(1,1) disturbances displaying moderate degrees of nonstationarity ($\theta >$ 0.7). Furthermore, it was shown that the performance of these charts is significantly affected by the presence of the autoregressive parameter (ie., when $\phi >$ 0.2). A case study involving a C$\sb3$ splitter provided the basis for development of a six-step procedure for the integration of SPC with APC. While carrying out integration on the C$\sb3$ splitter it was determined that the cause of disturbance nonstationarity must be sought out and removed if successful integration is to be achieved. For most nonstationary disturbances the amount of natural drift is often greater than or equal to the size of the step shifts that one is trying to detect. Thus, one is not able to differentiate between the common cause and assignable cause disturbances. (Abstract shortened by UMI.)

Abstract:
In an attempt to provide a better understanding of product costing system design, this study utilises the contingency theory approach to investigate the contingent relationships between several contextual factors and the design of product costing system simultaneously. This study also investigates the contingent relationships between several contextual factors with the importance of cost-plus pricing, and the mediating effect of the importance attached to cost-plus pricing on the relationship between contingent factors and product costing system design. In addition, this study investigates the implications of fit, internal consistency or coalignment between the contextual factors and product costing system design on organisational effectiveness. This study also seeks to develop a wider and more comprehensive view of product costing system design than the approach that has generally been used by previous studies (i. e. classifying costing systems by two discrete alternatives, either traditional or ABC systems). In addition, in today's competitive environment comprehensive product cost systems should provide increased accuracy for managerial decisions concerning products, pricing and discontinuing and/ or reengineering existing products. In markets where there is a generally accepted market price, firms have limited power to make pricing adjustments. Undoubtedly firms have to decide which products to sell and to determine the target product mix. Therefore, undertaking periodic profitability analysis is of vital importance. In the more common situation, where the market price is not given a priori, cost-plus pricing may be used whereby an appropriate percentage mark-up is added to the estimated cost to determine the proposed selling price. Therefore where cost information is used for cost-plus pricing decisions accurate cost information is likely to be crucial. While there is a substantial literature on costing systems, far less is known about the use of cost data in pricing decisions and profitability analysis. A distinguishing feature of the research is that it provides a contribution to the research literature on the understanding of the role that cost information plays in determining the selling prices and profitability analysis. A cross-sectional survey employing a questionnaire method of data collection was adopted. A total of 152 usable responses were received representing a response rate of 17%. For purposes of analysis, the research utilises descriptive statistics and structural equation modeling (SEM) multivariate statistical techniques enabled by EQS 5.7 version software (Bentler, 1995). Thus, this study is one of the first studies in product costing systems and cost-plus contingency literature to utilise SEM for validating the research constructs, controlling measurement error and for testing the structural relationships between the constructs simultaneously. Also, this is the first study to investigate and compare product costing practices in a single industry (i. e. the food industry) with the other UK industries, and therefore, examining and controlling to some extent for industry effects for the observed practices. The results of the descriptive analysis show that direct costing measures are extensively used for costplus pricing and profitability analysis purposes. Other absorption costing measures are also used but to a significantly lesser extent. Despite the popularity of the cost-plus pricing approach, only 50% of the companies report using it in their price setting with emphasis being more given to market factors such as competition and demand. The findings also emphasise that analysing the profitability of products and services at periodic intervals is considered to be a vitally important task. The results of structural equation modelling suggest a strong support for the influence in determining selling prices, importance of cost information, aspects relating to the intensity of competition, and the extent of the use of total quality management have a significant influence on the level of cost system sophistication. This research also provided insightful findings relating to the effectiveness of sophisticated costing systems. The results also indicate that market share, customisation, the influence in determining selling prices, aspects of differentiation strategy, intensity of competition, and the importance of cost information influence the importance of cost-plus pricing. Finally, this study contributes to the literature by utilising the structural equation modelling method, which has several advantages over other multivariate data analysis.

Abstract:
FundaÃÃo Cearense de Apoio ao Desenvolvimento Cientifico e TecnolÃgico
Os sucos de frutas sÃo importantes fontes de vitaminas, sais minerais, Ãcidos orgÃnicos e fibras, e incluÃdos na dieta da populaÃÃo podem ajudar a manter a saÃde. Durante as etapas de processamento de sucos, podem ocorrer modificaÃÃes nos componentes dos frutos, afetando suas propriedades sensoriais e nutritivas. Estudos sobre os efeitos do processamento nos constituintes nutricionais dos sucos tropicais sÃo escassos. Geralmente, sÃo avaliadas somente as perdas de vitamina C. Este trabalho objetivou determinar as possÃveis alteraÃÃes quÃmicas e fÃsico-quÃmicas em suco tropical de goiaba durante as etapas de processamento (extraÃÃo, formulaÃÃo / homogeneizaÃÃo e pasteurizaÃÃo) e armazenamento (30 dias). Foram efetuadas determinaÃÃes de sÃlidos solÃveis, pH, acidez, aÃÃcares redutores, aÃÃcares totais, atividade de Ãgua, cor, vitamina C, antocianinas, carotenÃides, compostos fenÃlicos e atividade da pectinametilesterase. Ao final do estudo, constatou-se que somente os parÃmetros de pH, carotenÃides e atividade da pectinametilesterase apresentaram variaÃÃes significativas, durante as etapas de processamento do suco. O suco de goiaba se manteve ao final do processamento com elevados teores de vitamina C, compostos fenÃlicos, antocianinas totais, alÃm do aumento da quantidade de carotenÃides totais. No suco de goiaba armazenado por 30 dias observou-se que os parÃmetros analisados nÃo apresentaram diferenÃa significativa entre o tempo zero e o trinta dias. Concluindo que as caracterÃsticas quÃmicas e fÃsico-quÃmicas sÃo pouco afetadas pelo processamento e armazenamento (30 dias), pode-se considerar, portanto o processo de enchimento à quente (hot fill), as embalagens de vidro utilizadas e os conservantes adicionados como sendo bons fatores de preservaÃÃo para o produto em estudo.
Fruit juices are important vitamin sources, mineral salts, organic acids and fibers, and including in the diet of the population, they can help to keep people healthy. During the stages of juice processing, some modifications in the fruit compounds can happen, affecting its sensorial and nutritional properties. Researches on the effects of processing on the nutritional compound tropical juice are scarce. Usually, only vitamin C losses are evaluated. This study determined the possible chemical and physical-chemical changes during the stages of guava tropical juice processing (extration, formulation / homogenization and pausterization) and storage (30 days). Soluble solids, pH, acidity, reducing sugars, total sugars, water activity, colour, vitamin C, anthocyanins, carotenoids, phenolic compounds and pectinametilesterase activity were analysed. We saw that only pH, carotenoids and pectinametilesterase activity parameters showed significant variations during the stages of juice processing. At the end of the processing, vitamin C, phenolic compounds and total anthocyanins contents were high, and it was an increase of total carotenoid amount in the guava juice. For the guava juice stored during 30 days it was observed no significant difference between the times zero and thirty days, for the analysed parameters. We conclude that since the chemical and physicochemical characteristics were affected just a little by processing and stored during 30 days, the hot fill processing, the glass packings used and added conservant were good factors of product preservation in this study.

Abstract:
Phenol and cresols represent a good example of primary chemical building blocks of which 2.8 million tons are currently produced in Europe each year. Currently, these primary phenolic building blocks are produced by refining processes from fossil hydrocarbons: 5% of the world-wide production comes from coal (which contains 0.2% of phenols) through the distillation of the tar residue after the production of coke, while 95% of current world production of phenol is produced by the distillation and cracking of crude oil. In nature phenolic compounds are present in terrestrial higher plants and ferns in several different chemical structures while they are essentially absent in lower organisms and in animals. Biomass (which contain 3-8% of phenols) represents a substantial source of secondary chemical building blocks presently underexploited. These phenolic derivatives are currently used in tens thousand of tons to produce high cost products such as food additives and flavours (i.e. vanillin), fine chemicals (i.e. non-steroidal anti-inflammatory drugs such as ibuprofen or flurbiprofen) and polymers (i.e. poly p-vinylphenol, a photosensitive polymer for electronic and optoelectronic applications). European agrifood waste represents a low cost abundant raw material (250 millions tons per year) which does not subtract land use and processing resources from necessary sustainable food production. The class of phenolic compounds is essentially constituted by simple phenols, phenolic acids, hydroxycinnamic acid derivatives, flavonoids and lignans. As in the case of coke production, the removal of the phenolic contents from biomass upgrades also the residual biomass. Focusing on the phenolic component of agrifood wastes, huge processing and marketing opportunities open since phenols are used as chemical intermediates for a large number of applications, ranging from pharmaceuticals, agricultural chemicals, food ingredients etc. Following this approach we developed a biorefining process to recover the phenolic fraction of wheat bran based on enzymatic commercial biocatalysts in completely water based process, and polymeric resins with the aim of substituting secondary chemical building blocks with the same compounds naturally present in biomass. We characterized several industrial enzymatic product for their ability to hydrolize the different molecular features that are present in wheat bran cell walls structures, focusing on the hydrolysis of polysaccharidic chains and phenolics cross links. This industrial biocatalysts were tested on wheat bran and the optimized process allowed to liquefy up to the 60 % of the treated matter. The enzymatic treatment was also able to solubilise up to the 30 % of the alkali extractable ferulic acid. An extraction process of the phenolic fraction of the hydrolyzed wheat bran based on an adsorbtion/desorption process on styrene-polyvinyl benzene weak cation-exchange resin Amberlite IRA 95 was developed. The efficiency of the resin was tested on different model system containing ferulic acid and the adsorption and desorption working parameters optimized for the crude enzymatic hydrolyzed wheat bran. The extraction process developed had an overall yield of the 82% and allowed to obtain concentrated extracts containing up to 3000 ppm of ferulic acid. The crude enzymatic hydrolyzed wheat bran and the concentrated extract were finally used as substrate in a bioconversion process of ferulic acid into vanillin through resting cells fermentation. The bioconversion process had a yields in vanillin of 60-70% within 5-6 hours of fermentation. Our findings are the first step on the way to demonstrating the economical feasibility for the recovery of biophenols from agrifood wastes through a whole crop approach in a sustainable biorefining process.

The technique of near infrared chemical imaging has been widely used for many industrial applications. It offers selectivity and/or sensitivity for numerous organic functional groups. The advantage of the near infrared spectroscopic region is the linear relationship of absorbance and concentration that enables quantitation. This universally employed technique has been a boon for research studies in the industrial process of wheat milling for the production of flour. The milling process has numerous sequential grinding and sieving steps that enable selective physical segregation of a starch rich endosperm product from wheat. Thousands of spectra of purified endosperm and non-endosperm standards are collected to develop a spectral library. Quantitation of the purity of individual processing streams is accomplished by applying a partial least squares calibration that is based upon the spectral library. The quantitative chemical imaging technique is useful for determination of endosperm purity profiles for mill flour streams. These plots reveal purity changes as less pure streams are added to produce a flour blend. The chemical structural basis furthermore allows comparison of purity even with changes in the wheat blend being milled with representative standardization. Furthermore, whereas a certain section of sieves is responsible, for designating the material defined as flour, application of the spectroscopic method is obvious. Select examples of key processing streams were studied to show the possibility of sieve-by-sieve analysis of the physical separation to provide mill optimization. These novel methods of analysis would not be possible without the sensitive and selective method of quantitative chemical imaging. Application of this technique to a few select unit processes is projected to reasonably affect a 1% increase in the yield of high quality flour. This amounts to a significant financial gain against low profit margins.

Smith, Matthew Robert. "The effects of industrial processing and chemical variation on the near-surface properties of poly(ethylene terephthalate) films and bottles." Thesis, Durham University, 2004. http://etheses.dur.ac.uk/2975/.

Full text
Abstract:
The sub-micron surface region of poly(ethylene terephthalate) (PET) films and bottles has been investigated. Uniaxially drawn and annealed PET films were characterised by bulk and grazing incidence X-ray diffraction (GIXD). Surface-specific diffraction patterns collected below the critical angle (ɑc) for total external reflection reveal a radial shift in diffraction peaks, whereas bulk signals collected above this critical angle occur at the predicted locations. It is calculated that this shift can be described by a ~5 % reduction of the a, b and c unit cell imrameters for PET crystals within the sub-micron surface region. This shift is less apparant in the un-oriented specimens. The crystallite orientation is consistently higher within the surface region of the drawn PET films than the bulk. There is a good agreement between the X-ray diffraction and FTIR orientation measurement over the range of films analysed. Polarised FTIR-ATR spectroscopy was used to map the molecular orientation along the inner and outer surfaces of stretch-blown PET bottles. This work reveals complex orientation trends. For 2-litre bottles, the inner surface shows consistently higher orientation levels than the outer surface. There are also two orientation switches at the shoulder and base regions on the outer surface, but only one switch on the inner wall. In all cases, the maximum orientation occurs on the inner surface at 4-6 cm from the base. This analysis was repeated for various bottles, including examples produced from various polyester co-polymers and a series of bottles stretch-blown after different preform heating times. Heating for 5 seconds longer than the recommended time prior to the stretch seriously reduces the orientation in the finished bottle. Lowering the polymer molecular weight has a similar effect. The use of the popular 1340 cm"' PET IR band for crystallinity evaluation was questioned. It is concluded that the use of this band for crystallinity calculation is erroneous if the specimen possesses molecular orientation. It is shown that the 1340 cm"' band height reveals the orientation trends in highly drawn specimens of low crystallinity. Simple measurements reveal that the 1340 cm ' transition moment for this band lies approximately in the chain direction.

An oxidative roasting of industrial spent Co-Mo/Al2O3 catalyst for hydrotreating diesel fuel with lime in an air atmosphere with the capture of sulfur and carbon oxides in the form of gypsum and calcite has been developed. The optimal conditions for the process have been determined. It has been established that the roasting of uncrushed spent catalyst makes it possible, during further processing, to separate molybdenum from aluminum and cobalt oxides by leaching, as well as to obtain lime and send it for roasting.

Abstract:
Electro-Chemical Machining (ECM) is an advanced machining technology. It has been applied to highly specialized fields such as aerospace, aeronautics and medical industries. However, it still has some problems to be overcome. The efficient tool-design, electrolyte processing, and disposal of metal hydroxide sludge are the typical issues. To solve such problems, CFD is considered to be a powerful tool in the near future. However, the numerical method that can satisfactorily predict the flow has not been established because of the complex flow natures. In the present study, we develop a numerical code and simulate the three-dimensional flow in the ECM process of compressor blades. Visualizing the computed flow field, the characteristics of the flow between the tool and the blade are investigated. It is exhibited that the over-machining occurs due to the Joule’s heating and the flow deviation around the leading and trailing edges.

Abstract:
In chemical processing industries, heating, cooling and other thermal processing of viscous fluids are an integral part of the unit operations. Static mixers are often used in continuous mixing, heat transfer, and chemical reactions applications. In spite of wide spread usage, the flow physics of static mixers is not fully understood. For a given application, besides experimentation, the modern approach to resolve this is to use powerful computational fluid dynamics (CFD) tools to study static mixer performance. This paper extends a previous study by the authors on an industrial helical static mixer and investigates heat transfer and mixing mechanisms within a helical static mixer. A three-dimensional finite volume simulation is used to study the performance of the mixer. The effects of different flow conditions on the performance of the mixer are studied. Heat transfer rates for a flow in a pipe containing no mixer is compared to that with a helical static mixer.

In the present study, we investigate the modelling of the three-phase flow (i.e. fluid, hydrogen bubble and metal sludge) in ECM process. First, the developed code is applied to the two-dimensional channel configuration. The interactions among three-phases and the dissolved wall are simulated, to verify the modelling and to determine the model parameters, Next, the sinusoidal channel is machined by our code. It is confirmed that hydrogen bubbles in the separation region suppress the dissolution of the wall, and make the final wall shape be wavy. Through this study, it is exhibited that our developed model and code are sound and useful for simulating ECM process.

Abstract:
Electro-Chemical Machining (ECM) is an advanced machining technology and has been applied to highly specialized fields, such as aerospace, aeronautics, and medical industries. However, some problems remain to be solved. The efficient tool-design, electrolyte processing, and disposal of metal hydroxide sludge are typical problems. To solve such problems, CFD is thought to have potential as a powerful tool. However, a numerical method that can satisfactorily predict the ECM process has not been established because of the complex flow natures. In a previous study, we presented a new model to simulate the flow fields in an ECM process. This model is based on a two-way coupling method, taking the interaction between gas and liquid phases into account. In this coupling method, we assumed that electrolyte and generated hydrogen bubbles over a cathode surface have the same velocity. Therefore, we could simplify the governing equations. Since the flow field had a non-uniform density distribution due to hydrogen bubbles, a low Mach number approximation was applied to solve the pressure Poisson equation. In the present study, we calculate hydrogen bubble trajectories and investigate the distribution and a behavior of hydrogen bubbles. Since hydrogen bubbles follow fluid well, they travel along the stream line. This is because hydrogen bubbles have small density. In the results, around the low velocity region, hydrogen bubbles remain there with making the spiral structure. Hydrogen particles remain more in the suction side than that in the pressure side of the blade.

Abstract Experimental studies of the subsonic combustion process have been conducted in order to determine the quality and economics of polyester, epoxy, urethane, and hybrid polyester-epoxy coatings. Thermally sprayed polymer coatings are of interest to several industries for anti-corrosion applications, including the infrastructural, chemical, automotive, and aircraft industries. Classical experiments were conducted, from which a substantial range of thermal processing conditions and their effect on the resultant coating were obtained. The coatings were characterized and evaluated by a number of techniques, including Knoop microhardness tests, optical metallography, image analysis, and bond strength. Characterization of the coatings yielded thickness, bond strength, hardness, and porosity.
