Method of separating organic vapors from gaseous media

A method of separating organic vapors from gaseous media, comprising the steps of:

• subjecting said gaseous media to pressure and to precooling by a first refrigerant to derive precooled gaseous media and a first condensate, including said first refrigerant;
• scrubbing said precooled gaseous media in a two-stage cold scrubber to reduce the temperature of said gaseous media by first and second flows of a second refrigerant to a temperature sufficiently low to separate from said scrubbed gaseous media a second condensate of said organic vapors including said second refrigerant, whereby at first refrigeration parameters one of said first and second flows of said second refrigerant provides refrigeration derived from an extraneous source of refrigeration, and at second refrigeration parameters the other of said first and second flows of said second refrigerant provides refrigeration derived from a first heat exchanger;
• separating from said scrubbed gaseous media residual organic vapors as a third condensate;
• feeding said scrubbed gaseous media through said first heat exchanger and feeding said third condensate through a second heat exchanger provided in the flow of said other refrigerant flow;
• removing water from said first, second and third condensates;
• and collecting said first, second and third condensates as water-free valuable substances.
