<p>Recovery of a halogenated hydrocarbon is performed by removing the halogenated hydrocarbon from an accompanying gas and/or temporarily storing the halogenated hydrocarbon on sorption filters, and releasing the halogenated hydrocarbon in targeted manner. The halogenated hydrocarbon serves for removal of an expiration gas using a steam carrier. A flow of the halogenated hydrocarbon takes place through two sorbents, (1) a hydrophobic carbon molecular sieve and (2) a hydrophobic zeolite, in two sorbent beds, spatially following one another. Air mixed with steam or steam has a temperature of the gases between 90° C. and 100° C. at normal pressure. In a filter for carrying out theabove recovery method, two filter beds are disposed to spatially follow one another.</p> |
