(371f) Performance Evaluation and Comparison of Conventional and Emerging Adsorbents in Their Applications to a CO2 Capture Vacuum Pressure Swing Adsorption (VPSA) Process
AIChE Annual Meeting
Tuesday, November 15, 2022 - 3:30pm to 5:00pm
The CO2 capture VSA runs with an adsorption cycle of five steps comprising high-pressure feed, heavy reflux, counter-current depressurization (blowdown), low-pressure purge and light product pressurization steps.
Each adsorbent candidate was assessed with respect to CO2 product recovery that is achievable by the simple CO2 VPSA process where the adsorption columns are packed with the adsorbent candidate. The performance of each VSA cycle was analysed by equilibrium theory that requires adsorption isotherms, bed void fraction and adsorbent density only .
