Abstract
Helium is introduced as an additive to any of the oxygen streams introduced into an ozone generator, such as a dielectric discharge (cold plasma) ozone generator, where the effluent of the generator is directed to an adsorption process for separating the ozone from the oxygen. Also disclosed is an improved PSA cycle, which is designed to reduce the amount of make-up helium and oxygen required to sustain the ozone generation and recovery process.
