“…In contrast to traditional solvents, only the CO 2 -rich phase is sent for regeneration; therefore, the energy demand and the size of the regenerator can be dramatically reduced in comparison to non-phase-change solvents. Gomez et al compared the performance of phasechange solvent process to the conventional MEA process, showing the CO 2 capture cost could be saved by 15.4% for the power plant, and as much as 51.7% for the cement plant (Gomez et al, 2014). Although the phase-change absorbent systems exhibit some potential merits and economic incentives for scaling up, they may be volatile and corrosive due to the use of amine solution in nature.…”

Carbon Capture From Flue Gas and the Atmosphere: A Perspective

2020

Climate change has become a worldwide concern with the rapid rise of the atmospheric Co2 concentration. To mitigate Co2 emissions, the research and development efforts in Co2 capture and separation both from the stationary sources with high Co2 concentrations (e.g., coal-fired power plant flue gas) and directly from the atmosphere have grown significantly. Much progress has been achieved, especially within the last twenty years. In this perspective, we first briefly review the current status of carbon capture technologies including absorption, adsorption, membrane, biological capture, and cryogenic separation, and compare their advantages and disadvantages. Then, we focus mainly on the recent advances in the absorption, adsorption, and membrane technologies. Even though numerous optimizations in materials and processes have been pursued, implementing a single separation process is still quite energy-intensive or costly. To address the challenges, we provide our perspectives on future directions of Co2 capture research and development, that is, the combination of flue gas recycling and hybrid capture system, and one-step integrated Co2 capture and conversion system, as they have the potential to overcome the technical bottlenecks of single capture technologies, offering significant improvement in energy efficiency and cost-effectiveness.

“…This feature makes it possible to achieve high cyclic loadings (e.g., 10.56-14.08 wt%). Compared to MEA technology, the use of DMX-1 could lead to 3.8% increase in power plant efficiency and 15.4% reduction in cost [26]. In another two studies, approximately 30 aqueous amines (lipophilic amines and alkanolamines) and the combination of them were screened and shown in Table 3 (The amines appeared in Table 1 are not included in Table 3) [27,28].…”

Carbon capture is the most probable technology in combating anthropogenic increase of CO 2 in the atmosphere. Works on developing emerging absorbents for improving carbon capture performance and reducing process energy consumption are actively going on. The most worked-on emerging absorbents, including liquid-liquid biphasic, liquid-solid biphasic, enzymatic, and encapsulated absorbents, already show encouraging results in improved energy efficiency, enhanced CO 2 absorption kinetics, increased cyclic CO 2 loading, or reduced regeneration temperature. In this chapter, the latest research and development progress of these emerging absorbents are reviewed along with the future directions in moving these technologies to higher-technology readiness levels.

“…Chemical absorption with solvents is a mature technology [3], which was first implemented at industrial scale in Denmark on a power station with monoethanolamine (MEA) [4]. Other options using solutions of demixing amines were studied in [5][6][7][8] and showed a better energetic efficiency of the process. Other solvent types were also investigated [9][10][11].…”

Environmental Performances of Various CCU Options in the Framework of an Integrated Chemical Plant

Several carbon capture processes are investigated to separate a part of the CO2 contained in the flue gas of a coal-fired power plant located in a chemical integrated plant, with the objective of using it as a raw material in a production process. The expected results are to reduce the impact on global warming potential (GWP) and to increase the productivity of the plant. The study is based on the modelling of the combination of systems in the plant using a process simulation software and using life cycle assessment to evaluate both technical feasibility and environmental aspects. Models for the power plant, the production processes, amine chemical absorption, membrane separation and adsorption on activated coal are developed and validated against industrial and literature data. The life cycle inventory is obtained from the mass and energy balances given by the systems model. A first set of calculations is launched with a high purity requirement for the CO2 stream (95%) recycled into the process. Those calculations show a 12% increase in productivity for the chemical process considered, but result in no significant gain in terms of GWP. Conversely, scenarios with a lower CO2 purity (40%) show a drop around 9% of the impacts on GWP using membrane separation and activated coal adsorption, while keeping the other impacts at about the same level.
