Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
129 words
THE METHOD OF TREATING RELATIVELY HIGH PRESSURE HYDROCARBON FEED GAS CONTAINING METHANE AND CONDENSABLE COMPONENTS TO PRODUCED OUTPUT GAS AT RELATIVELY LOW PRESSURE, THAT INCUDES; (A) COOLING SAID HIGH PRESSURE GAS TO BELOW 32*F., (B) EXANDING THE COOLED GAS THROUGH A TURBINE TO PRODUCE A GAS-CONDENSATE MIXTURE AT A TEMPERATURE BELOW ABOUT -100*F., (C) DELIVERING THE GAS-CONDENSATE MIXTURE AT A TEMPERATURE BELOW ABOUT -100*F. TO A STRIPPING COLUMN, (D) STRIPPING THE CONDENSATE TO REMOVE A CONDENSABLE COMPONENT THEREOF AT A PRESSURE BELOW THE OUTPUT GAS PRESSURE, (E) FLOWING GAS FROM THE STRIPPING COLUMN IN HEAT EXCHANGE RELATIONSHIP WITH THE FEED GAS, AND (F) RECOMPRESSING GAS FROM THE STRIPPING COLUMN, AFTER IT HAS BEEN HEAT EXCHANGED WITH THE FEED GAS, BY THE ENERGY OUTPUT OF SAID TURBIME SAID OUTPUT GAS.
