FLARELESS CONDENSATE STABILIZATION IN COMBINATION WITH GAS CONDITIONING

摘要

THE INVENTION RELATES TO A PROCESSING SCHEME FOR GAS CONDITIONING, COMPRISING AN EXPANSION-COOLING BASED SEPARATION STAGE (200) AND A STABILISATION STAGE (300) THE EXPANSION-COOLING BASED SEPARATION STAGE (200) COMPRISES AN EXPANDER (EXP), A SEPARATOR (SEP) AND A COMPRESSOR (COM), AND IS ARRANGED TO RECEIVE AN INPUT STREAM (12). THE STABILISATION STAGE (300) COMPRISES A FRACTIONATION COLUMN (FC), AND IS ARRANGED TO RECEIVE AN INTERMEDIATE INPUT STREAM (13) FROM THE EXPANSION-COOLING BASED SEPARATION STAGE (200). THE PROCESSING SCHEME FURTHER COMPRISES A JET PUMP (JP), ARRANGED TO RECEIVE AT LEAST PART OF A FRACTIONATION TOP STREAM (FT) AND A PORTION OF THE INPUT STREAM (12?) TAKEN UPSTREAM OF THE EXPANDER (EXP), TO COMBINE THESE INTO A FEEDBACK STREAM (FS) WHICH IS RE-INTRODUCED IN THE EXPANSION-COOLING BASED SEPARATION STAGE (200) AT A FEEDBACK POSITION. [FIG. 3]
