The current project aims to design and optimize the cryogenic CO2 capture process in terms of CO2 removal efficiency and energy requirement. The serious concern of global warming due to increasing CO2 emission has urged policymakers to employ various CO2 capture methods. Note that among different CO2 capture methods, the cryogenic capture is a favorable option since it uses less energy and no chemicals in the CO2 removal process. Cryogenic CO2 capture suffers from high equipment costs and energy consumption.
