ABSTRACT:
A pressure swing adsorption apparatus to vary selectively the concentration of at least one constituent of a gaseous mixture by sending a gaseous mixture into an adsorber to generate a particular product gas while delivering to another adsorber both a predetermined portion of the product gas to purge the other adsorber of its adsorbed gas and a selected amount of the product gas, independent of the flow rate and in addition to the predetermined portion, to produce a desired relative concentration of the constituents of the product gas from a range of relative concentrations.
