This study explored the feasibility of integrat-ing an adsorption and solvent scrubbing process for post-combustion CO2 capture from a coal-fired power plant.This integrated process has two stages:the first is a vacuum swing adsorption(VSA)process using activated carbon as the adsorbent,and the second stage is a solvent scrubber/stripper system using monoethanolamine(30 wt-％)as the solvent.The results showed that the adsorption process could enrich CO2 in the flue gas from 12 to 50 mol-％with a CO2 recovery of＞90％,and the concentrated CO2 stream fed to the solvent scrubber had a significantly lower volumetric flowrate.The increased CO2 concentration and reduced feed flow to the absorption section resulted in significant reduction in the diameter of the solvent absorber,bringing the size of the absorber from unecono-mically large to readily achievable domain.In addition,the VSA process could also remove most of the oxygen initially existed in the feed gas,alleviating the downstream corrosion and degradation problems in the absorption section.The findings in this work will reduce the technical risks associated with the state-of-the art solvent absorption technology for CO2 capture and thus accelerate the deployment of such technologies to reduce carbon emissions.
