Abstract: HEAVY COMPONENTS OF HYDROCARBON GAS MIXTURES ARE RECOVERED THROUGH PARTIAL CONDENSATION OF A FIRST PORTION OF THE STARTING GAS BY INDIRECT HEAT EXCHANGE WITH A REFRIGERANT WHEREIN THE CONDENSATE FORMED IS ENTRAINED IN THE GAS STREAM. THE CONDENSATE IS SEPARATED FROM THE RESULTING PARTIALLY CONDENSED, TWO-PHASE MIXTURE AND THE SEPARATED CONDENSATE IS THEN THERMALLY STRIPPED OF LIGHT COMPONENTS BY HEAT EXCHANGE WITH A SECOND PORTION OF THE STARTING GAS WHICH IS THEREBY ALSO PARTIALLY CONDENSED. HEAVY COMPONENTS FROM THE STARTING GAS MIXTURE ARE RECOVERED AS STRIPPED HYDROCARBON CONDENSATE. (FIG. 4)
