ABSTRACT:
The system comprises a sequential set of heat exchangers, wherethrough a gaseous mixtures to be treated is forced to flow.
An initial length of the set provides for the cooling of the mixture by means of a refrigerating system such that the condensable products are liquefied and recovered; thereafter, residual purified air is heated by the heat generated in the codenser of the refrigerating system operating as a heat pump.
The system is specially useful for purifying the effluents of dry-cleaning plants utilizing chlorinated solvents.
