The invention deals with a process for separating ethylene oxide and dichlorodifluoromethane from a mixture containing air in addition thereto. …<??>According to the invention the process comprises a first step consisting in contacting the gaseous air-containing mixture (2) into an absorption zone (3) with a counter-current (6) of an organic liquid solvent and a second step consisting in passing the bottoms (8) of the first step into a desorption zone (9) for recovering a gaseous overhead (10) of ethylene oxide and dichlorodifluoromethane and liquid bottoms (16) of the said solvent, the two zones (3 and 9) being connected in series in a closed system and submitted each to specific pressure and temperature conditions. …<??>This process is especially suitable for recovering ethylene oxide and dichlorodifluoromethane in industrial sterilizer using this gas as a sterilization gas. |
