| 摘要 |
An ozone-oxygen gas stream is introduced into the feed side (18) of a membrane separation unit S containing an elastomeric polymer membrane (16). Ozone-enriched gas passes through the membrane (16) to a permeate zone (20) and is either contacted with an ozone-reactive substance-containing gas stream in the permeate zone (20), thereby oxidizing the substances or is removed from the permeate zone (20). Removal of the ozone-enriched gas from the permeate zone (20) may be effected by purging the permeate zone (20) with an inert gas and/or evacuating the permeate zone (20). Ozone-enriched gas removed from the permeate zone (20) may be mixed with a liquid or gas stream which contains ozone-reactive substances in, for example, a venturi device V, thereby oxidizing the substances. <IMAGE> |
