Abstract
A method of treating a gas stream that includes: performing a first pressure swing adsorption (PSA) process generating a first H-product gas and a first PSA tail gas from a first feed gas, the first PSA tail gas including a residual Hand CO; separating COfrom the first PSA tail gas using a COselective membrane, generating a CO-rich permeate gas and a CO-lean rejected gas; performing a second PSA process generating a second H-product gas and a second PSA tail gas from a second feed gas, the second PSA tail gas including another residual H; mixing the CO-lean rejected gas and the second PSA tail gas to generate a mixed tail gas; and separating the residual Hand the another residual Hfrom the mixed tail gas using an Hselective membrane, generating a recovered Hpermeate gas and a final rejected gas.
