This paper describes a process for treating a gas mixture including a sterilant gas and a diluent gas. It comprises: feeding the gas mixture to a first separation process to substantially remove the sterilant from the gas mixture; withdrawing a treated gas stream from the first separation process; feeding the treated gas stream to a second separation process, comprising passing at least a portion of the treated gas stream through a membrane separation unit containing a permselective membrane; withdrawing from the separation unit a first stream enriched in the diluent gas compared with the gas mixture; withdrawing from the membrane separation process a second stream depleted in the diluent gas compared with the gas mixture.
