A METHOD FOR EXTRACTING NATURAL GAS GASOLINE BOILING RANGE HYDROCARBONS FROM A NATURAL GAS CONTAINING SUCH HYDROCARBONS COMPRISING CHILLING SAID NATURAL GAS FROM A TEMPERATURE WITHIN THE RANGE OF BOUT 75* TO 110* F. AT A PRESSURE WITHIN THE RANGE OF ABOUT 500 TO 600 P.S.I.A. TO A TEMPERATURE WITHIN THE APPROXIMATE RANGE OF -15* TO 0* F. BY INDIRECT HEAT EXCHANGE WITH A GAS PHASE AS SUBSEQUENTLY PRODUCED, MIXING WITH THE CHILLED NATURAL GAS A CHILLED NATURAL GAS GASOLINE HAVING A REID VAPOR PRESSURE OF ABOUT 12 POUNDS AS DETERMINED BY ASTM METHOD D323-37T AT A TEMPERATURE WITHIN THE APPROXIMATE RANGE OF -15* TO 0* F. AT SAID PRESSURE, FURTHER CHILLING THIS MIXTURE BY INDIRECT HEAT EXCHANGE WITH A REFRIGERANT TO A TEMPERATURE WITHIN THE APPROXIMATE RANGE OF -40* TO -25* F. AT ABOUT SAID PRESSURE, SEPARATING THIS FURTHER COOLED MIXTURE AT SAID PRESSURE AND AT SAID TEMPERATURE WITHIN SAID APPROXIMATE RANGE OF -40* TO -25* F. INTO A GAS PHASE AND A LIQUID PHASE, SAID GAS PHASE BEING SAID GAS PHASE AS SUBSEQUENTLY PRODUCED, PASSING SAID LIQUID PHASE AT ABOUT ITS SEPARATION TEMPERATURE AND PRESSURE IN INDIRECT HEAT EXCHANGE WITHA NATURAL GAS GASOLINE THEREBY PRODUCING THE AFOREMENTIONED CHILLED NATURAL GAS GASOLINE AT A TEMPERATURE WITHIN THE APPROXIMATE RANGE OF -15* TO 0* F. AND WARMING SID LIQUID PHASE
