Claim 1
Independent Claim
147 words
THE METHOD OF FRACTIONATING A HYDROCARBON MIXTURE INCLUDING, PASSING THE HYDROCARBON MIXTURE INTO CONTACT WITH ONE SIDE OF AN INDIRECT HEAT EXCHANGE SURFACE TO EFFECT SELECTIVE CONDENSATION THEREON OF LESS VOLATILE COMPONENTS OF THE HYDROCARBON MIXTURE WHILE MAINTAINING VAPORS OF SAID HYDROCARBON MIXTURE IN COUNTER-CURRENT CONTACT WITH THE CONDENSATE ON SAID HEAT EXCHANGE SURFACE, COLLECTING THE CONDENSATE, REDUCING PRESSURE ON THE CONDENSATE FOR COOLING THE CONDENSATE, DIRECTING THE COOLED CONDENSATE IN DESCENDING CONTACT WITH THE OTHER SIDE OF THE INDIRECT HEAT EXCHANGE SURFACE TO RECEIVE HEAT FROM SAID HYDROCARBON MIXTURE FOR VAPORIZING THE MORE VOLATILE COMPONENTS THEREOF WHILE MAINTAINING THE VAPORS IN STRIPPING CONTACT WITH SAID CONDENSATE, INCREASING THE PRESSURE OF THE LAST FORMED VAPOR, UNITING SAID LAST FORMED VAPOR WITH THE INFLUENT HYDROCARBON MIXTURE FOR ASCENSION THERWITH IN SAID HEAT EXCHANGE CONTACT TO EFFECT CONDENSATION OF THE LESS VOLATILE COMPONENTS, AND SEPARATELY REMOVING SAID SEPARATED COMPONENTS.
