Simulation and Optimization of Key Equipment and Energy-Saving Process for Marine Carbon Capture System
Aiming at the problems of limited installation space of marine carbon capture equipment and high regeneration heat consumption during desorption process,based on Aspen Plus simulation software,a model of carbon capture process system for marine exhaust gas was built,and the size of the absorber and desorption tower and the packing structure were optimized. Both the packing height of absorber and desorption tower can be reduced by 30％ or more,which could achieve CO2 capture efficiency of more than 90％ while reducing the regeneration heat consumption by more than 14％. Further combined with the interstage cooling process,the rich liquid diverting process,the lean liquid flash process,and the engine exhaust waste heat utilization,the efficient,compact and low energy consumption CO2 capture of ship exhaust is achieved,and the CO2 regeneration heat consumption is as low as 2.1GJ/t.
