Abatement of CO2 emissions has become a global environmental issue. Post-combustion CO2 capture using chemical absorbent is a mature method for CCS. This study deals with the modeling and simulation of CO2 capture process with aqueous monoethanolamine (MEA), with the application of a commercial simulator UniSim Design®. In order to systematically improve energy efficiency of CO2 capture process and to consider design options of structural modifications superstructure-based optimization technique is applied by minimizing total operating costs. The optimization is carried out by a stochastic solver within MATLAB®, linking with the simulator to determine optimal design configuration and operating conditions. The case study illustrates how the proposed modeling and optimization is effective for investigating design options for improving energy efficiency for amine-based CO2 capture processes.
