Title:
PROCESS AND DEVICE FOR THE REMOVAL OF ETHYLENE OXIDE GAS
Document Type and Number:
WIPO Patent Application WO1992020432
Kind Code:
A3
Abstract:
The invention concerns a process for the removal of ethylene oxide gas at high concentrations, for instance 1,000 to 1,000,000 ppm, such as occurs in gas sterilization chambers. The removal process calls for the ethylene oxide gas to be adsorbed by an adsorbant in the dry state and/or to be absorbed and/or catalytically reacted by an absorbant and/or catalyst carrier in the wet state in the presence of a catalyst and/or oxidized or reduced by an oxidizing-agent or reducing-agent carrier which can act as a catalyst and/or filler, depending on the oxidizing or reducing agent used, in the wet state, with the addition of an oxidizing or reducing agent.
