Process and plant for treatment of a gas mixture including ozone

摘要

A process for treatment of a secondary gas including ozone, comprising the steps of: a) adding an adjacent gas including CO2 to the secondary gas to form a mixture of secondary gas and adjacent gas; b) passing the mixture of secondary gas and of adjacent gas obtained at the end of stage a) into at least one stock of adsorbent, where the ozone is completely or partly adsorbed; c) sweeping the stock of adsorbent with the aid of a desorbing gas including CO2, and discharging from an outlet of the stock an output gas including ozone, wherein the ozone has a concentration which is higher in the output gas than the ozone concentration of the secondary gas.
