Abstract
A PROCESS AND AN APPARATUS ARE DISCLOSED FOR THE RECOVERY OF ETHANE, ETHYLENE, PROPANE, PROPYLENE, AND HEAVIER HYDROCARBON COMPONENTS FROM A HYDROCARBON GAS STREAM IN A COMPACT PROCESSING ASSEMBLY. THE GAS STREAM IS COOLED AND DIVIDED INTO FIRST AND SECOND STREAMS. THE FIRST STREAM IS FURTHER COOLED TO CONDENSE SUBSTANTIALLY ALL OF IT AND IS THEREAFTER EXPANDED TO LOWER PRESSURE AND HEATED TO FORM A VAPOR FRACTION AND A LIQUID FRACTION. THE LIQUID FRACTION IS SUPPLIED AS A FIRST TOP FEED TO AN ABSORBING MEANS INSIDE THE PROCESSING ASSEMBLY. THE SECOND STREAM IS ALSO EXPANDED TO LOWER PRESSURE AND SUPPLIED AS THE BOTTOM FEED TO THE ABSORBING MEANS. A FIRST DISTILLATION VAPOR STREAM IS COLLECTED FROM THE UPPER REGION OF THE ABSORBING MEANS AND COMBINED WITH THE VAPOR FRACTION TO FORM A COMBINED VAPOR STREAM. THE COMBINED VAPOR STREAM IS DIRECTED TO A FIRST HEAT AND MASS TRANSFER MEANS INSIDE THE PROCESSING ASSEMBLY SO THAT IT IS COOLED BY THE EXPANDED FIRST STREAM SUFFICIENTLY TO PARTIALLY CONDENSE IT, FORMING A SECOND DISTILLATION VAPOR STREAM AND A CONDENSED STREAM. THE CONDENSED STREAM IS SUPPLIED AS A SECOND TOP FEED TO THE ABSORBING MEANS, AND THE SECOND DISTILLATION VAPOR STREAM IS DIRECTED INTO ONE OR MORE HEAT EXCHANGE MEANS INSIDE THE PROCESSING ASSEMBLY TO HEAT IT WHILE COOLING THE GAS STREAM AND THE FIRST STREAM. A DISTILLATION LIQUID STREAM IS COLLECTED FROM THE LOWER REGION OF THE ABSORBING MEANS AND DIRECTED INTO A SECOND HEAT AND MASS TRANSFER MEANS INSIDE THE PROCESSING ASSEMBLY TO HEAT IT AND STRIP OUT ITS VOLATILE COMPONENTS WHILE COOLING THE GAS STREAM. THE QUANTITIES AND TEMPERATURES OF THE FEEDS TO THE ABSORBING MEANS ARE EFFECTIVE TO MAINTAIN THE TEMPERATURE OF THE UPPER REGION OF THE ABSORBING MEANS AT A TEMPERATURE WHEREBY THE MAJOR PORTIONS OF THE DESIRED COMPONENTS ARE RECOVERED IN THE STRIPPED DISTILLATION LIQUID STREAM.
