Design and experiment of high-productivity two-stage vacuum pressure swing adsorption process for carbon capturing from dry flue gas
文献摘要：
A two-stage vacuum pressure swing adsorption(VPSA)process that coupled kinetically controlled and equilibrium controlled separation process with reflux has been investigated for capturing carbon dioxide from dry flue gas(85％N2/15％CO2).In the first enriching stage,carbon molecular sieve(CMS),which shows kinetic selectivity for CO2/N2,is adopted as the adsorbent to remove most N2 in feed gas,thereby upgrading CO2 and significantly reducing the amount for further refinement.The second stage loads zeo-lite 13X as adsorbent to purify the CO2-rich flow from the first stage for meeting the requirements of National Energy Technology Laboratory.Series of experiments have been conducted for adsorption iso-therms measuring and lab-scale experimental validation as well as analysis.The effect of feed composi-tion on the separation performance of the PSA system was studied experimentally and theoretically here.The optimal results achieved 95.1％purity and 92.9％recovery with a high CO2 productivity(1.89 mol CO2·h-1·kg-1)and an appropriate energy consumption of 1.07 MJ·(kg CO2)-1.Further analysis has been carried out by simulation for explicating the temperature,pressure,and concentration distribution at cyclic steady state.
