Simultaneous Design and Control of the MEA Absorption Process of a CO2 Capture Plant

AbstractThis paper presents the simultaneous design and control of the MEA absorption section of a post-combustion CO2 capture plant. An optimization framework is proposed to minimize the process economics while complying with the process constraints in the transient domain using a decentralized control scheme. The optimal design obtained by the proposed methodology has been validated and compared against the traditional optimal steady-state design approach. The results indicate that the proposed design is dynamically feasible in the presence of oscillatory disturbances in the flue gas flowrate
