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)

Abstract: MERCURY IS REMOVED FROM NATURAL GAS BY CONTACTING THE GAS WITH A RELATIVELY MERCURY-FREE LIQUID STATE HYDROCARBON AND RECOVERING A MERCURY-LEAN METHANE-RICH GAS AND A MERCURY-ENRICHED HYROCARBON LIQUID. THE MERCURY-FREE HYDROCARBON LIQUID MAY BE OBTAINED BY SEPARATION OF MERCURY FROM THE MERCURY-ENRICHED HYDROCARBON LIQUID OR ITS DERIVATIVE STREAMS. (FIG. 1)
