ABSTRACT:
The strongly adsorbed component of a gas mixture is produced in enhanced purity and yield by novel PSA cycles. The basic steps of the cycles include an adsorption vessel prepressurization step, a cocurrent nonadsorbed gas production step, a cocurrent purge step with strongly adsorbed gas product and a countercurrent depressurization step which produces the strongly adsorbed gas product that is used in the cocurrent purge step. In addition to the basic steps, a first depressurization equalization step precedes or follows the cocurrent purge step and a corresponding first pressurization equalization step follows the countercurrent depressurization step. The cycle optionally includes one or two depressurization equalization steps before the cocurrent purge step and one or two corresponding pressurization equalization steps after the first pressurization equalization step.
