Patent ID: 7392657

Claim:
A method of dissolving ozone in a liquid cryogen, comprising the steps of: a) providing a liquified cryogen; b) allowing a gaseous stream of ozone to flow into at least one adsorption unit containing an adsorbent material thereby adsorbing ozone thereupon; c) allowing the cryogen to flow to the at least one adsorption unit, thereby extracting an amount of the ozone adsorbed upon the adsorbent material in step (b), wherein the cryogen is in either a liquid, gaseous or supercritical phase as it flows through the adsorption unit; d) allowing a majority of the combined cryogen and extracted ozone from step (c) to flow from the at least one adsorption unit to a container, wherein a pressure and temperature of the cryogen are maintained at levels such that the cryogen is maintained in the liquid state: e) allowing another stream of gaseous ozone to flow into the at least one adsorption unit containing an adsorbent material thereby adsorbing ozone thereupon; f) allowing at least a portion of the cryogen with dissolved ozone to flow to the at least one adsorption unit, thereby extracting an amount of the ozone adsorbed upon the adsorbent material in step (e); and g) allowing a majority of the combined cryogen and extracted ozone from step (f) to flow out of the at least one adsorption unit.
