This paper investigates different configurations for solvent-based post-combustion carbon capture processes. The aim of this paper is to find the best process configuration for amine stripping process to be used for further study. From the literature, some of the most energy-efficient schemes are identified and compared in different scenarios. It was found that for absorber, the two most talked about configurations worth investigating are inter-cooling and pump-around, while for stripper modification, rich split, lean vapor compression (LVC), and a new configuration-phase separation heat exchanger (PSHE) have shown quite promising results, although the best way of comparison would be the techno-economic analysis of all the configurations; from heuristics, two stand-alone modifications for absorber, pump-around and inter-cooling; and three stripper modifications, rich split, LVC, and PSHE combined with absorber inter-cooling are simulated and compared based on their energy consumption. The next step of this work will be the total cost calculation and heat integration of these schemes with power plant.
