“…Many researchers were focusing on the MEA-based CO 2 capture in coal-fired and gas-fired power plants owing to its largest share of anthropogenic CO 2 emissions, the effect of the CO 2 capture process on the overall plant efficiency and electricity price has been studied, and efforts have been made in order to compensate the plant efficiency as well (Abu-Zahra et al, 2007a;Dave et al, 2011;Duan et al, 2012;Gupta et al, 2015). Later, the research effort was shifted to other industrial sectors, as industrial emissions were considered as another important CO 2 source.…”

CO2 capture using monoethanolamine (MEA) is one of the important decarbonization options and often considered as a benchmark, while the optimal MEA contraction and systematic process study are still lacking. In this work, firstly, the MEA concentrations between 15 and 30 wt% were studied from both process simulations with Aspen Plus and experimental measurements in the pilot-scale. 20 wt% MEA was identified as the preferable solution. Subsequently, a systematic analysis was conducted for CO2 capture using 20 wt% MEA with/without CO2 compression to study how various parameters, including gas flow rate, CO2 concentration, and CO2 removal rate, affected the energy demand and techno-economic performances quantitatively. The influence of each parameter on both energy demand and cost showed an obvious non-linear relationship, evidencing the importance of systematic analysis for further study on decarbonization. The evaluation indicated that the regeneration heat required the largest portion of energy demand. The economic analysis showed that the capital cost was more sensitive to the selected parameters than the operational cost, while the operational cost created a major change in the overall cost. In addition, the gas flow rate and CO2 concentration were the main parameters affecting the cost, rather than the CO2 removal rate. Finally, it was suggested that, for a new plant, CO2 capture showed the minimum investment cost per ton CO2 when operating the plant on a large scale, high CO2 concentration, and high CO2 removal rate; for an existing plant, the capture preferred to run with the high CO2 removal rate.

“…Vaccarellia et al performed an economic evaluation of a post-combustion carbon capture process integrated in a power plant cycle. Gupta et al presented a techno-economic analysis of absorber intercooling and multipressure stripper. Similar work was done by Li et al Four process configurations (i.e., absorber intercooling, rich-amine split, modified rich-amine split, and stripper interheating) are assessed considering capital and operating costs.…”

A techno-economic optimization of a commercial-scale, amine-based, post-combustion CO 2 capture process is carried out. The most economically favorable process configuration, sizing and operating conditions are identified using a superstructure formulation. The superstructure has 12 288 possible process configurations and unit operations in the superstructure are described using rigorous, rate-based models. In order to simplify the optimization problem, the problem is decomposed and process simulations are explicitly handled in the process simulator. Optimization is performed externally using a genetic algorithm. The best found process configuration includes the absorber intercooling, the rich vapor recompression, and the cold solvent split. The result of this study is compared in terms of the cost of capture basis and shows 38% reduction on the annual operation cost, compared to the conventional amine-based CO 2 capture process. Moreover, the savings on the total annualized cost is ∼13%, which is an increase of 30% on the annualized investment cost resulting from additional unit operations.
