Method of stabilizing raw gasoline

Claim 1

A PROCESS FOR THE SEPARATION AND RECOVERY OF A STABLIZIED LIQUID FRACTION FROM A WET HYDROCARBON GAS MIXTURE COMPRISING PASSING A FEED STREAM OF SAID GAS TO A FIRST COMPRESSION ZONE AND TO A FIRST COOLING ZONE, COMPRESSING AND COOLING SAID GAS IN SAID COMPRESSION ZONE AND SAID COOLING ZONE TO A PRESSURE AND TEMPERATURE TO CONDENSE FROM SAID GAS A COLD LIQUID HYDROCARBON FRACTION, PASSING SAID GAS AND SAID COLD LIQUID FRACTION TO A FIRST SEPARATION ZONE, SEPARATING UNCONDENSED GAS FROM SAID COLD LIQUID FRACTION IN SAID FIRST SEPARATION ZONE, REMOVING COLD LIQUID FRACTION FROM SAID FIRST SEPARATION ZONE, PASSING DIRECTLY TO A GAS-LIQUID CONTACT ZONE SAID COLD LIQUID FRACTION AT A TEMPERATURE NOT SUBSTANTIALLY HIGHER THAN ITS TEMPERATURE IN SAID FIRST SEPARATION ZONE, REMOVING UNCONDENSED GAS FROM SAID FIRST SEPARATION ZONE, PASSING SAID GAS FROM SAID FIRST SEPARATION ZONE TO A SECOND COMPRESSION ZONE AND TO A SECOND COOLING ZONE, COMPRESSING AND COOLING SAID GAS IN SAID SECOND COMPRESSION ZONE AND SAID SECOND COOLING ZONE TO A PRESSURE AND TEMPERATURE TO CONDENSE FROM SAID GAS A COLD LIQUID HYDROCARBON FRACTION, PASSING SAID GAS AND SAID COLD LIQUID FRACTION TO A SECOND SEPARATION ZONE, SEPARATING UNCONDENSED GAS FROM SAID LIQUID FRACTION IN SAID SECOND SEPARATION ZONE, REMOVING UNCONDENSED GAS FROM SAID SECOND SEPARATION ZONE, REMOVING SAID COLD LIQUID FRACTION FROM SAID SECOND SEPARATION ZONE, PASING SAID COLD LIQUID FRACTION FROM SAID SECOND SEPARATION ZONE TO A PRESSURE REDUCTION ZONE, REDUCING THE PRESSURE ON SAID COLD LIQUID FRACTION IN SAID PRESSURE REDUCTION ZONE TO SEPARATE A GAS PHASE THEREFROM, REMOVING SAID GAS PHASE FROM SAID PRESSURE REDUCTION ZONE, ADMIXING SAID GAS PHASE REMOVED FROM SAID PRESSURE REDUCTIN ZONE WITH SAID GAS ENTERING SAID SECOND COMPRESSION AND COOLING ZONES, REMOVING SAID LIQUID FRACTION FROM SAID PRESSURE REDUCTION ZONE, PASSING SAID LIQUID FRACTION TO SAID GAS-LIQUID CONTACT ZONE, PASSING SAID LIQUID FRACTIONS THROUGH SAID GASLIQUID CONTACT ZONE TO A HEATING ZONE, HEATING SAID LIQUID FRACTIONS IN SAID HEATING ZONE TO STABILIZE SAID LIQUID FRACTIONS BY VAPORIZING THEREFROM A GAS PHASE CONTAINNG UNDESIRED LIGHT HYDROCARBON, PASSING SAID GAS PHASE THROUGH SAID GAS-LIQUID CONTACT ZONE IN COUNTERCURRENT CONTACT WITH ONLY SAID LIQUID FRACTIONS PASSING THROUGH SAID GAS-LIQUID CONTACT ZONE, REMOVING SAID GAS PHASE FROM SAID GAS-LIQUID CONTACT ZONE, PASSING THE ENTIRE AMOUNT OF SAID GAS PHASE REMOVED FROM SAID GAS-LIQUID CONTACT ZONE DIRECTLY TO SAID FIRST COMPRESSED ZONE, AND RECOVERING A STABLIZED LIQUID FRACTION FROM SAID HEATING ZONE.
