ABSTRACT:
A pressure swing adsorption cycle designed to reduce the variations in ozone concentration, and produce a higher average ozone concentration, in a product gas stream throughout the cycle. The cycle includes a relatively long air sweep stage and provides for the overlapping of the air sweep stage in two adsorber vessels. Effluent from an adsorber vessel in a feed rinse stage is routed to another adsorber vessel that is in an air sweep stage.
