Progress in organic vapor purification and recovery by pressure swing adsorption technology

The research progress in pressure swing adsorption(PSA) technology in purifying and separating organic vapor was reviewed,covering the topics of PSA separating and recycling low,mid and high-organic vapor,adsorbent used in PSA,and the technique and process of PSA separating and recycling organic vapors.The research directions were as follows:new PSA adsorbent,integration technology for various separation processes,process optimization,intelligent control system,PSA separation of multiple composition organic vapor,simulating PSA process by computers to enhance theoretical studies on adsorption in PSA,and the theory on mass and heat transfer in adsorption and desorption process.
