Treating materials with ozone

A method of producing ozone comprises passing oxygen rich gas from a PSA plant 2 through an ozoniser 4 and then passing the ozonised oxygen thus formed directly back to the PSA plant 2 where the ozone is adsorbed in a bed 10, 10' of adsorbent material contained within a vessel 6, 8. During a de...

Zusammenfassung:	A method of producing ozone comprises passing oxygen rich gas from a PSA plant 2 through an ozoniser 4 and then passing the ozonised oxygen thus formed directly back to the PSA plant 2 where the ozone is adsorbed in a bed 10, 10' of adsorbent material contained within a vessel 6, 8. During a desorption step nitrogen adsorbed in a bed 12, 12' also located in the vessel 6, 8 desorbs the ozone from the bed 10, 10' and a nitrogen-ozone gas leaves the PSA plant 2 via a line 44.
