Abstract
A high pressure purge is incorporated into the cycle of a PSA process designed for the recovery of strongly adsorbed product gas from a gas mixture. The high pressure purge stream is obtained by compressing the low pressure cocurrent purge step that precedes the countercurrent depressurization or evacuation step. The high pressure purge step is included in the cycle following the adsorption step of the process.
