Abstract:

Abstract: Rapid industrialization and sudden growth of population around the globe from the 18th century onwards ultimately led to the uncontrolled growth of manufacturing and energy producing industries. To make processes economical industries side lined the environment which began showing its effects from the past 50 years. Ever since Global Warming (commonly attributed to the unhealthy quantities of greenhouse gasses) starting to take up the centre stage, environmentalist and chemical engineers around the globe felt the need to reinvent our industrial processes to balance economy with environmental health. Through the medium of this report we intend to highlight yet another essential need of the hour that not only has the potential to reverse the damage of high carbon release by industries but also maintain economics of plant operation. Although Carbon capture is already a subject that is in study by scientists and engineers around the globe we intend to contribute and understand its plausibility using technology and simulation as a tool to facilitate better understanding of Co2 extraction from flue gasses

Abstract:

Reducing CO2 emissions from the use of fossil fuel is the primary purpose of carbon dioxide capture and storage (CCS). Two basic approaches to CCS are available.1,2 In one approach, CO2 is captured directly from the industrial source, concentrated into a nearly pure form, and then pumped deep underground for long-term storage (see Figure 1). As an alternative to storage in underground geological formations, it has also been suggested that CO2 could be stored in the ocean. This could be done either by dissolving it in the mid-depth ocean (1–3 km) or by forming pools of CO2 on the sea bottom where the ocean is deeper than 3 km and, consequently, CO2 is denser than seawater. The second approach to CCS captures CO2directly from the atmosphere by enhancing natural biological processes that sequester CO2 in plants, soils, and marine sediments. All of these options for CCS have been investigated over the past decade, their potential to mitigate CO2 emissions has been evaluated,1 and several summaries are available.1,3,4

Abstract:

A membrane-based system with a retentate recycle process in tandem with an enriching cascade was studied for >90% carbon capture from coal flue gas. A highly CO2-selective facilitated transport membrane (FTM) was utilized particularly to enhance the CO2 separation efficiency from the CO2-lean gases for a high capture degree. A techno-economic analysis showed that the retentate recycle process was advantageous for ≤90% capture owing to the reduced parasitic energy consumption and membrane area. At >90% capture, the enriching cascade outperformed the retentate recycle process since a higher feed-to-permeate pressure ratio could be applied. An overall 99% capture degree could be achieved by combining the two processes, which yielded a low capture cost of USD47.2/tonne, whereas that would be USD 42.0/tonne for 90% capture. This FTM-based approach for deep carbon capture and storage can direct air capture for the mitigation of carbon emissions in the energy sector.

Abstract:

Human-generated carbon emissions are the leading cause of climate change. There is a global commitment to reduce carbon emissions, in an effort to limit climate change effects. Many climate change solutions involve the mitigation of carbon emissions, mitigation alone is not enough. Carbon Dioxide (CO2) can live in the atmosphere for over 100 years. If we were to switch to 100% renewable energies, we would still damage the planet with the stagnant CO2 from the 1920’s. To combat climate change, we need a solution that can remove this carbon. One such solution is carbon capture, one of our best weapons in tackling climate change. The replacement of fossil fuel energy will not happen in the next few years, maybe not even for decades. Therefore, carbon capture is a promising ‘bridge’ technology, while we reach a sustainable level of green energy production. Carbon capture technology development has largely focused on singular processes (typically absorption, adsorption and membranes) capturing carbon from industrial exhaust systems. Recently, studies have delved into the idea of combining two or more of these technologies into one more efficient system and employing them in the industrial exhaust systems but also capturing carbon from the atmosphere. This project aims to develop a hybrid membrane and adsorption unit to capture carbon directly from the atmosphere. The aim is to provide the technology necessary to remove carbon from the atmosphere more effectively and cheaper than earlier technologies.

Abstract:

This paper aims to pull together the main points, messages and underlying themes to emerge from the Discussion. It sets these remarks in the context of where Carbon Capture and Storage (CCS) fits into the spectrum of carbon mitigation solutions required to meet the challenging greenhouse gas (GHG) emissions reduction targets set by the COP21 climate change conference. The Discussion focused almost entirely on carbon capture (21 out of 23 papers) and covered all the main technology contenders for this except biological processes. It included (chemical) scientists and engineers in equal measure and the Discussion was enriched by the broad content and perspectives this brought. The major underlying theme to emerge was the essential need for closer integration of materials and process design – the use of isolated materials performance criteria in the absence of holistic process modelling for design and optimisation can be misleading. Indeed, combining process and materials simulation for reverse materials molecular engineering to achieve the required process performance and cost constraints is now within reach and is beginning to make a significant impact on optimising CCS and CCU (CO₂ utilisation) processes in particular, as it is on materials science and engineering generally. Examples from the Discussion papers are used to illustrate this potential. The take-home messages from a range of other underpinning research themes key to CCUS are also summarised: new capture materials, materials characterisation and screening, process innovation, membranes, industrial processes, net negative emissions processes, the effect of GHG impurities, data requirements, environment sustainability and resource management, and policy. Some key points to emerge concerning carbon transport, utilisation and storage are also included, together with some overarching conclusions on how to develop more energy- and cost-effective CCS processes through improved integration of approach across the science-engineering spectrum. The discussion was first-rate in the best traditions of Faraday Discussions and hopefully will foster and stimulate further cross-disciplinary interactions and holistic approaches.

Abstract:

Carbon Capture and Storage (CCS) is an important tool for the decarbonization of the energy system to achieve the mid-century global climate change targets. CO2 is captured using diﬀerent industrial processes that involve membrane filtering or enhanced combustion. The CO2 is then transported, preferably by pipeline, to a storage site where it is injected into a permeable reservoir. Sealing capacity of the storage site is of paramount importance for safe CO2 sequestration, to avoid any geological leakage. Each CCS project must have a dedicated MMV (Measurement, Monitoring and Verification) programme to ensure conformance with the expected evolution of the CO2 plume and its containment within the storage site. Eni is committed to the implementation of CCS, with several ongoing projects.

Abstract:

Carbon capture and storage (CCS) is a method used to capture CO2 that is produced via the combustion of fossil fuels and then store it away from the atmosphere for a long time. The focus of CCS is on power generation and industrial sectors, mainly because they emit such a large volume of carbon dioxide that the capture and storage there will be the most beneficial. The most researched/developed ways to capture CO2 are pre-combustion capture, post-combustion capture, and oxyfuel combustion capture. Once the carbon dioxide is captured, it can either be stored underground or stored in the ocean. Source of CO2 seriously affecting our planet. The major factor in increased global warming comes from carbon dioxide emission. Coal fire power plants, cement/brick factories, oil refineries, natural gas wells, and transportation all emit CO2 from the burning of fossil fuels. Many countries are planning to set mandatory caps on CO2 emissions, causing companies to develop and test methods to mitigate their carbon footprint. This study focuses on the processes and techniques of CCS technology as well as challenges and policy concerns.

Abstract:

Major fossil fuel consumption associated with CO2 emission and socioeconomic instability has received much concern within the global community regarding the long-term sustainability and security of these commodities. The capture, sequestration, and conversion of CO2 emissions from flue gas are now becoming familiar worldwide. Nanostructured carbonaceous materials with designed functionality have been extensively used in some key CO2 exploitation processes and techniques, because of their excellent electrical conductivity, chemical/mechanical stability, adjustable chemical compositions, and abundant active sites. This review focuses on a variety of carbonaceous materials, like graphene, carbon nanotubes, amorphous porous carbons and carbon hybrid composites, which have been demonstrated promising in CO2 capture/separation and conversion (electrocatalysis and photocatalysis) to produce value-added chemicals and fuels. Along with the discussion and concerning synthesis strategies, characterization and conversion and capture/separation techniques employed, we further elaborate the structure-performance relationships in terms of elucidating active sites, reaction mechanisms and kinetics improvement. Finally, challenges and future perspectives of these carbon-based materials for CO2 applications using well-structured carbons are remarked in detail.

Abstract:

Carbon Dioxide Utilisation (CDU) processes face significant challenges, especially in the energetic cost of carbon capture from flue gas and the uphill energy gradient for CO₂reduction. Both of these stumbling blocks can be addressed by using alkaline earth metal compounds, such as Grignard reagents, as sacrificial capture agents. We have investigated the performance of these reagents in their ability to both capture and activate CO₂directly from dried flue gas (essentially avoiding the costly capture process entirely) at room temperature and ambient pressures with high yield and selectivity. Naturally, to make the process sustainable, these reagents must then be recycled and regenerated. This would potentially be carried out using existing industrial processes and renewable electricity. This offers the possibility of creating a closed loop system whereby alcohols and certain hydrocarbons may be carboxylated with CO₂and renewable electricity to create higher-value products containing captured carbon. A preliminary Techno-Economic Analysis (TEA) of an example looped process has been carried out to identify the electrical and raw material supply demands and hence determine production costs. These have compared broadly favourably with existing market values.

Abstract:

The development of more efficient processes for CO2 capture from the flue streams of power plants is considered a key to the reduction of greenhouse gas emissions implicated in global warming. Indeed, several U.S. and international climate change initiatives have identified the urgent need for improved materials and methods for CO2 capture. Conventional CO2 capture processes employed in power plants world-wide are typically postcombustion “wet scrubbing” methods involving the absorption of CO2 by amine-containing solvents such as methanolamine (MEA). These present several disadvantages, including the considerable heat required in regeneration of the solvent and the necessary use of inhibitors for corrosion control, which lead to reduced efficiencies and increased costs for electricity production. This perspective article seeks to highlight the most recent advances in new materials for CO2 capture from power plant flue streams, with particular emphasis on the rapidly expanding field of metal–organic frameworks. Ultimately, the development of new classes of efficient, cost-effective, and industrially viable capture materials for application in carbon capture and storage (CCS) systems offers an immense opportunity to reduce atmospheric emissions of greenhouse gases on a national and international scale.

Abstract:

Summary Recent progress in carbon capture, utilization, and storage (CCUS) is reviewed. Considerable research effort has gone into carbon dioxide (CO2) capture, with many promising separation processes in various stages of development, but only a few have been tested at commercial scale, and considerable additional development will be required to determine competitiveness of new technologies. Processes for direct capture of CO2 from the air are also under development and are starting to be tested at pilot scale. Transportation of CO2 to storage sites by pipeline is well-established, though substantially more pipeline capacity will be required if CCUS is to be undertaken at a large scale. Considerable experience has now been built up in enhanced-oil-recovery (EOR) operations, which have been under way since the 1970s. Storage in deep saline aquifers has also been achieved at scale. Recent large-scale projects that capture and store CO2 are described, as are current and potential future markets for CO2. Potential effects of changes in the US tax code Section 45Q on those markets are summarized. Future deployment of CCUS will depend more on cost reductions for CO2 separations, development of new markets for CO2, and the complexities of project finance than on technical issues associated with storage of CO2 in the subsurface.

Abstract:

One of society’s major current challenges is carbon dioxide emissions and their consequences. In this context, new technologies for carbon dioxide (CO2) capture have attracted much attention. One of these is carbon capture and utilization (CCU). This work focuses on the latest trends in a holistic approach to carbon dioxide capture and utilization. Absorption, adsorption, membranes, and chemical looping are considered for CO2 capture. Each CO2 capture technology is described, and its benefits and drawbacks are discussed. For the use of carbon dioxide, various possible applications of CCU are described, starting with the utilization of carbon dioxide in agriculture and proceeding to the conversion of CO2 into fuels (catalytic processes), chemicals (photocatalytic processes), polymers, and building supplies. For decades, carbon dioxide has been used in industrial processes, such as CO2-enhanced oil recovery, the food industry, organic compound production (such as urea), water treatment, and, therefore, the production of flame retardants and coolants. There also are several new CO2-utilization technologies at various stages of development and exploitation, such as electrochemical conversion to fuels, CO2-enhanced oil recovery, and supercritical CO2. At the end of this review, future opportunities are discussed regarding machine learning (ML) and life cycle assessment (LCA).

Abstract:

Carbon capture and storage (CCS) have been investigated for a long time. It was intended to reduce carbon dioxide (CO2) in the atmosphere due to fossil fuel combustion in power generation and industrial processes. CO2 is captured and stored in various geological formations. The problem here is to match between source and sink such that alternative storage and unutilized storage capacities are minimum. Pinch Design Method as has been proposed by was used in this work. The concept is overwhelming that it can be used other than in the heat exchanger networks, such as in the water system design, mass exchanger networks and many other processes. Initially this concept was applied to carbon capture and storage but with no exact pairing between sources and sinks as proposed in this work using grid diagram as commonly shown in other processes. This work can point out the exact pairing between sources and sinks, and within the given time frame. A four different cases are investigated where the time difference between the starting time of CO2 generated in the source and the beginning of sink availability. A value of 0, 5, 10 and 15 years are chosen to evaluate the amount of CO2 that has to be stored and the amount of unutilized storage capacity. The case study has been prepared with 5 sources and 3 sinks. The result shows that the larger time difference the larger alternative storage and unutilized storage capacities. Therefore, having a shorter time difference will be more acceptable in the design CCS system.

Abstract:

The need to cut CO 2 emission into the atmosphere is pushing scientists and technologists to discover and implement new strategies that may be effective for controlling the CO 2 atmospheric level (and its possible effects on climate change). One option is the capture of CO 2 from power plant flue gases or other industrial processes to avoid it entering the atmosphere. The captured CO 2 can be either disposed in natural fields (geological cavities, spent gas or oil wells, coal beads, aquifers; even oceans have been proposed) or used as a source of carbon in synthetic processes. In this paper, we present the options for CO 2 utilization and make an analysis of possible solutions for the conversion of large volumes of CO 2 by either combining it with H 2 , that must be generated from water, or by directly converting it into fuels by electrolysis in water using solar energy. A CO 2 –H 2 -based economy may address the issue of reducing the environmental burden of energy production, also saving fossil carbon for future generations. The integration of CO 2 capture and utilization with CO 2 capture and storage would result in a more economically and energetically viable practice of CO 2 capture.

A state-of-the-art analysis is proposed with a critical comparison to gas absorption technology, which is still considered as the best available technology for this application. The possibilities offered by high-performance membrane materials (zeolites, Carbon Molecular Sieves, Metal Oxide Frameworks, graphenes, facilitated transport membranes, etc.) are discussed in combination to process strategies (multistage design, hybrid processes, energy integration). The future challenges and open questions of membranes for carbon capture are finally proposed.

Abstract:

Abstract: More than ever, the fate of anthropogenic CO2 emissions is in our hands. Since the advent of industrialization, there has been an increase in the use of fossil fuels to fulfil rising energy demands. The usage of such fuels results in the release of carbon dioxide (CO2) and other greenhouse gases, which result in increased temperature. Such warming is extremely harmful to life on Earth. The development of technology to counter the climate change and spreading it for widespread adoptions. We need to establish a framework to provide overarching guidance for the well-functioning of technology and mechanism development of Carbon Capture and Storage. Carbon capture and storage (CCS) is widely regarded as a critical approach for achieving the desired CO2 emission reduction. Various elements of CCS, such as state-of-the-art technology for CO2 collection, separation, transport, storage, politics, opportunities, and innovations, are examined and explored in this paper. Carbon capture and storage is the process of capturing and storing carbon dioxide (CO2) before it is discharged into the environment (CCS). The technology can capture high amounts of CO2 produced by fossil fuel combustion in power plants and industrial processes. CO2 is compressed and transferred by pipeline, ship, or road tanker once it has been captured. CO2 can then be piped underground, usually to depths of 1km or more, and stored in depleted oil and gas reservoirs, coalbeds, or deep saline aquifers, depending on the geology. CO2 could also be used to produce commercially marketable products. With the goal of keeping world average temperatures below 1.5°C (2.7°F) and preventing global average temperature rises of more than 2°C (3.6°F) over pre-industrial levels, CCS model should be our priority to be implemented with the proper economical map

Abstract:

An essential line of worldwide research towards a sustainable energy future is the materials and processes for carbon dioxide capture and storage. Energy from fossil fuels combustion always generates carbon dioxide, leading to a considerable environmental concern with the values of CO2 produced in the world. The increase in emissions leads to a significant challenge in reducing the quantity of this gas in the atmosphere. Many research areas are involved solving this problem, such as process engineering, materials science, chemistry, waste management, and politics and public engagement. To decrease this problem, green and efficient solutions have been extensively studied, such as Carbon Capture Utilization and Storage (CCUS) processes. In 2015, the Paris Agreement was established, wherein the global temperature increase limit of 1.5 °C above pre-industrial levels was defined as maximum. To achieve this goal, a global balance between anthropogenic emissions and capture of greenhouse gases in the second half of the 21st century is imperative, i.e., net-zero emissions. Several projects and strategies have been implemented in the existing systems and facilities for greenhouse gas reduction, and new processes have been studied. This review starts with the current data of CO2 emissions to understand the need for drastic reduction. After that, the study reviews the recent progress of CCUS facilities and the implementation of climate-positive solutions, such as Bioenergy with Carbon Capture and Storage and Direct Air Capture. Future changes in industrial processes are also discussed.

The greatly risen level of atmospheric carbon dioxide after the industrial revolution leads to serious problems and concerns, including health issues and global warming. Therefore, the significance of carbon dioxide capture can not be overemphasized. Metal-organic framework (MOF), a brand-new and potential kind of material, can be utilized in several processes of CO2 capture because of its high capacity as well as high selectivity. In this review, the key parameters for evaluation of the MOF used for CO2 capture, which is directed related to the performance of materials, are addressed and discussed. Several important and practical evaluation indicators are also mentioned, for economic cost and stability, and tolerance to impurity. Additionally, factors that affect the performance of CO2 adsorption in both structural and external degrees of MOF are shown and reviewed. This article provides a different perspective of parameters for MOF materials and indicates critical features for the organic linkers and metal ions that are used to build the whole framework.

Abstract:

Various carbon dioxide (CO2) capture materials and processes have been developed in recent years. The absorption-based capturing process is the most significant among other processes, which is widely recognized because of its effectiveness. CO2 can be used as a feedstock for the production of valuable chemicals, which will assist in alleviating the issues caused by excessive CO2 levels in the atmosphere. However, the interaction of carbon dioxide with other substances is laborious because carbon dioxide is dynamically relatively stable. Therefore, there is a need to develop types of catalysts that can break the bond in CO2 and thus be used as feedstock to produce materials of economic value. Metal oxide-based processes that convert carbon dioxide into other compounds have recently attracted attention. Metal oxides play a pivotal role in CO2 hydrogenation, as they provide additional advantages, such as selectivity and energy efficiency. This review provides an overview of the types of metal oxides and their use for carbon dioxide adsorption and conversion applications, allowing researchers to take advantage of this information in order to develop new catalysts or methods for preparing catalysts to obtain materials of economic value.

Abstract:

The study of metaphorization processes in scientific texts is essential in terminological studies and the conceptual representation of specialized knowledge. It is considered to be a prolific tool in the creation of neologisms. Many cognitive models tried to study metaphorisation processes by drawing on metaphor and metonymy based on linguistic evidence. However, recent studies have highlighted the necessity of carrying out empirical tests in order to provide refined results that go beyond the traditional theories of conceptual metaphor and metonymy. This paper analyzes the underlying metaphor in the ‘carbon capture and sequestration’ event in both English and Arabic. It also discusses the influence of English, the lingua franca, in the transfer of the neologism ‘carbon capture and sequestration’, via translation processes, and its role in the so-called domain loss in the target language. Results were obtained through a corpus-based contrastive terminological analysis, extracted from specialized texts in English and Arabic in the subdomain of climate change. Data analysis was approached from the perspective of Frame-Based Terminology and Conceptual Complexes.

Abstract:

The greatest lever for advancing climate adaptation and mitigation is the defossilization of energy systems. A key opportunity to replace fossil fuels across sectors is the use of renewable hydrogen. In this context, the main political and social push is currently on climate neutral hydrogen (H2) production through electrolysis using renewable electricity. Another climate neutral possibility that has recently gained importance is biohydrogen production from biogenic residual and waste materials. This paper introduces for the first time a novel concept for the production of hydrogen with net negative emissions. The derived concept combines biohydrogen production using biotechnological or thermochemical processes with carbon dioxide (CO2) capture and storage. Various process combinations referred to this basic approach are defined as HyBECCS (Hydrogen Bioenergy with Carbon Capture and Storage) and described in this paper. The technical principles and resulting advantages of the novel concept are systematically derived and compared with other Negative Emission Technologies (NET). These include the high concentration and purity of the CO2 to be captured compared to Direct Air Carbon Capture (DAC) and Post-combustion Carbon Capture (PCC) as well as the emission-free use of hydrogen resulting in a higher possible CO2 capture rate compared to hydrocarbon-based biofuels generated with Bioenergy with Carbon Capture and Storage (BECCS) technologies. Further, the role of carbon-negative hydrogen in future energy systems is analyzed, taking into account key societal and technological drivers against the background of climate adaptation and mitigation. For this purpose, taking the example of the Federal Republic of Germany, the ecological impacts are estimated, and an economic assessment is made. For the production and use of carbon-negative hydrogen, a saving potential of 8.49–17.06 MtCO2,eq/a is estimated for the year 2030 in Germany. The production costs for carbon-negative hydrogen would have to be below 4.30 € per kg in a worst-case scenario and below 10.44 € in a best-case scenario in order to be competitive in Germany, taking into account hydrogen market forecasts.

Abstract:

With rising fuel demands, the carbon which is avowed as inefficient energy sources is continually declining. This method is a promiscuous way not of lowering CO2 emissions but of producing economic benefits. The physiochemical conversion of carbon dioxide into chemical (energy) goods without contamination. The production of microalgae will thus help to repair CO2 and biofuels sources. In this present work, we have done a comprehensive reviewed in this paper that carbon dioxide capture mechanism, contribution of microalgae for biomass production. As a result of using microalgae (S. platensis, Salmeriensis, and Scenedesmus dimorphus are capture maximum CO2 respectively of 1.00 and 0.81gL−1 d−1, 1.0gL−1day−1-2.8gL−1day−1 and 0.8g CO2 L−1d−1 with the production of microalgae biomass (<0.4g L-1day-1, 129.24 mg−1d−1, and 0.44gcel L−1d−1) in wastewater. The overall cost of the process is considerably reduced when these light conversion and chemical processes are combined, making carbon dioxide collection even more economically viable. Microalgae was used on extensively for biodiesel production and carbon dioxide reduction, and the processes were significantly enhanced with the use of microalgae. To conclude microalgae holds a strong promise in the 21st-century biofuel industry and environmentally friendly by capturing CO2. GUB JOURNAL OF SCIENCE AND ENGINEERING, Vol 8, Dec 2021 P 29-35

Abstract:

Microplastics (MPs), plastic particles <5 mm, are found in environments, including terrestrial ecosystems, planetwide. Most research so far has focused on ecotoxicology, examining effects on performance of soil biota in controlled settings. As research pivots to a more ecosystem and global change perspective, questions about soil-borne biogeochemical cycles become important. MPs can affect the carbon cycle in numerous ways, for example, by being carbon themselves and by influencing soil microbial processes, plant growth, or litter decomposition. Great uncertainty surrounds nano-sized plastic particles, an expected by-product of further fragmentation of MPs. A major concerted effort is required to understand the pervasive effects of MPs on the functioning of soils and terrestrial ecosystems; importantly, such research needs to capture the immense diversity of these particles in terms of chemistry, aging, size, and shape.

Abstract:

It is likely that the future availability of energy from fossil fuels, such as natural gas, will be influenced by how efficiently the associated CO2 emissions can be mitigated using carbon capture and sequestration (CCS). In turn, understanding how CCS affects the efficient recovery of energy from fossil fuel reserves in different parts of the world requires data on how the performance of each part of a particular CCS scheme is affected by both technology specific parameters and location specific parameters, such as ambient temperature. This paper presents a study into how the energy consumption of an important element of all CCS schemes, the CO2 compression process, varies with compressor design, CO2 pipeline pressure, and cooling temperature. Post-combustion, pre-combustion, and oxyfuel capture scenarios are each considered. A range of optimization algorithms are used to ensure a consistent approach to optimization. The results show that energy consumption is minimized by compressor designs with multiple impellers per stage and carefully optimized stage pressure ratios. The results also form a performance map illustrating the energy consumption for CO2 compression processes that can be used in further study work and, in particular, CCS system models developed to study performance variation with ambient temperature.

Abstract:

Carbon integration aims to identify appropriate CO2 capture, allocation, and utilization options, given a number of emission sources and sinks. Numerous CO2-using processes capture and convert emitted CO2 streams into more useful forms. The transportation of captured CO2, which poses a major design challenge, especially across short distances. This paper investigates new CO2 transportation design aspects by introducing pipeline merging techniques into carbon integration network design. For this, several tradeoffs, mainly between compression and pipeline costs, for merged pipeline infrastructure scenarios have been studied. A modified model is introduced and applied in this work. It is found that savings on pipeline costs are greatly affected by compression/pumping levels. A case study using two different pipe merging techniques was applied and tested. Backward branching was reported to yield more cost savings in the resulting carbon network infrastructure. Moreover, both the source and sink pressures were found to greatly impact the overall cost of the carbon integration network attained via merged infrastructure. It was found that compression costs consistently decreased with increasing source pressure, unlike the pumping and pipeline costs.

Abstract:

The increase in CO2 concentration in the atmosphere has prompted the research community to find solutions for this environmental problem, which causes climate change and global warming. CO2 removal through the use of negative emissions technologies could lead to global emission levels becoming net negative towards the end of this century. Among these negative emissions technologies, direct air capture (DAC), in which CO2 is captured directly from the atmosphere, could play an important role. The captured CO2 can be removed in the long term and through its storage can be used for chemical processes, allowing closed carbon cycles in the short term. For DAC, different technologies have been suggested in the literature, and an overview of these is proposed in this work. Absorption and adsorption are the most studied and mature technologies, but others are also under investigation. An analysis of the main key performance indicators is also presented here and it is suggested that more efforts should be made to develop DAC at a large scale by reducing costs and improving efficiency. An additional discussion, addressing the social concern, is indicated as well.

Abstract:

Abstract Blackwater has more benefits for carbon recovery than conventional domestic wastewater. Carbon capture and up-concentration are crucial prerequisites for carbon recovery from blackwater, the same as domestic wastewater. Both chemical enhanced primary treatment (CEPT) and high-rate activated sludge (HRAS) processes have enormous potential to capture organics. However, single CEPT is subject to the disruption of influent sulfide, and single HRAS has insufficient flocculation capacity. As a result, their carbon capture efficiencies are low. By combining CEPT and HRAS with chemical enhanced high rate activated sludge (CEHRAS) process, the limitations of single CEPT and single HRAS offset each other. The carbon mineralization efficiency was significantly influenced by SRT rather than iron salt dosage. An iron dosage significantly decreased chemical oxygen demand (COD) lost in effluent. Both SRT and iron dosage had a significant influence on the carbon capture efficiency. However, HRT had no great impact on the organic mass balance. CEHRAS allowed up to 78.2% of carbon capture efficiency under the best conditions. The results of techno-economic analysis show that decreasing the iron salt dosage to 10 mg Fe/L could promise profiting for blackwater treatment. In conclusion, CEHRAS is a more appropriate technology to capture carbon in blackwater.
