ON-LINE RECOVERY OF XENON FROM ANAESTHETIC GAS

摘要

A process is disclosed for separating a component from a gaseous mixture, in particular for separating xenon from the breathing gas exhaled by an anaesthetised patient. The disclosed process has the following steps: the gaseous mixture is brought into contact with a cooling surface at a temperature below the melting point of the components to be separated, the proportion of the gaseous mixture which is not condensed on the cooling surface in a solid state is carried away, and the component condensed on the cooling surface is heated above the melting point of the component to be separated. Also disclosed are a device for carrying out this process, a corresponding process for recovering anaesthetic gas and an associated anaesthetic equipment.
