Due to CO2 emission issue, there have been a number of suggested processes for CO2 capture such as various types of absorption, adsorption, and membrane processes. The hybrid process made by combining the absorption and membrane processes have been studied, but the combination of absorption and adsorption processes has been rarely covered. To show the possibility and to give the insight of the absorption-adsorption hybrid process, this study gives the results of the sensitivity analysis. The results are based on the simulation of one absorption-based CO2 capture process and adsorption-based CO2 capture process, which take monoethanolamine(MEA) and zeolite 13X as solvent and sorbent, respectively. Pressure swing adsorption (PSA) is also taken as adsorption process in this study. The main focus of this study is to the optimal CO2 capture load of each process. Namely, the split ratio with respect to the CO2 capture load is changed, and the results are observed. |
