Abstract
There is disclosed an improved PSA process and apparatus for gas enrichment wherein the pressure levels of the vent gas stream and/or product stream are used to drive gaseous diffusion cells to produce a feed gas stream and/or a purge gas stream to be used in the pressure swing adsorption process to increase on-line production time and to utilize the waste pressure energy thereby decreasing energy requirements per unit of production.
