“…On the other hand, these operating conditions influence energy savings in the AFS with PZ process, as described above. Numerical results from the present study are in agreement with those reported in the literature, 33 where it is stated that the energy performance of 5 molal PZ is better than 8 molal PZ and the CO 2 loading (mol CO 2 /mol alk.) should be in a range of 0.21−0.26.…”

“…Regarding the purchase equipment cost of the different process units, we use the capital cost correlation provided in the literature 70 and correlations built from the information available in the literature. 33 Regarding the operating cost, eq 29 shows the corresponding calculation, where CHU is the heating utility cost, CCU is the cooling utility cost, CE is the electricity cost, and CM is the cost of amine makeup. Another important economic indicator is the capture cost (CAPCOST), which is calculated with eq 30.…”

Post-combustion capture has the potential to mitigate climate change through the reduction of CO2 emissions in the short term. Chemical absorption-based processes are the most mature technology, but process costs should be reduced to facilitate their worldwide application. In this context, we address the optimal design of absorption-based carbon capture technologies using the Aspen Plus platform in the equation-oriented (EO) mode. We show the efficiency of this tool by solving optimal design problems for three case studies: (i) conventional process using monoethanolamine; (ii) conventional process using 2-methylpiperazine; and (iii) advanced flash stripping (AFS) configuration using piperazine (PZ). The objective function is the carbon dioxide avoided cost, and we consider a flue gas with a CO2 concentration of 7.5% (molar basis). Numerical results indicate that the AFS configuration with PZ has the best energy efficiency (2.46 GJ/t-CO2) and achieves the lowest CO2 avoided cost, with a value of 98.8 $/tonne-CO2.

“…Both Tables and highlight the existence of trade-offs between different desirable features. No sorbent performs perfectly across all metrics, but many perform sufficiently well to result in low thermodynamic and economic costs of CO 2 avoided and successful implementation in practice. Finding acceptable trade-offs can be an effective way to identify promising sorbents.…”

The processes that produce CO 2 and other acid gases (SO x , NO x , and H 2 S) generate value for society. However, these gases are environmental pollutants, and their emission into the atmosphere undermines the value they create. In the face of climate change, CO 2 emissions require attention on an unprecedented scale. Abatement technologies focused on carbon capture, storage, and utilization (CCUS) enable the continued use of processes and resources that produce CO 2 (and other acid gases) while minimizing their effect on the environment. This review explores the role sorbents play in emission abatement and the acid gas "economy". We identify 15 sorbent categories, evaluating their performance at both the material and the system levels. We conclude with anticipated research opportunities and future trends in acid gas separation.
