PROCESS FOR LIQUEFYING A HYDROCARBON-RICH STREAM

A METHOD FOR LIQUEFYING A HYDROCARBON-RICH FRACTION AND SIMULTANEOUSLY SEPARATING A C2+-RICH FRACTION IS DESCRIBED. IN SAID METHOD, THE HYDROCARBON-RICH FRACTION IS COOLED AND LIQUEFIED BY INDIRECTLY EXCHANGING HEAT WITH THE COOLANT MIXTURE OF A COOLANT MIXTURE CYCLE IN WHICH THE COOLANT MIXTURE IS...

Zusammenfassung:	A METHOD FOR LIQUEFYING A HYDROCARBON-RICH FRACTION AND SIMULTANEOUSLY SEPARATING A C2+-RICH FRACTION IS DESCRIBED. IN SAID METHOD, THE HYDROCARBON-RICH FRACTION IS COOLED AND LIQUEFIED BY INDIRECTLY EXCHANGING HEAT WITH THE COOLANT MIXTURE OF A COOLANT MIXTURE CYCLE IN WHICH THE COOLANT MIXTURE IS CONDENSED IN AT LEAST TWO STAGES, AND THE C2+-RICH FRACTION IS SEPARATED AT AN ADJUSTABLE TEMPERATURE LEVEL, WHEREIN THE COOLANT MIXTURE IS SEPARATED INTO A GASEOUS AND A LIQUID FRACTION, AND BOTH FRACTIONS ARE SUPER COOLED, ARE EXPANDED ESSENTIALLY TO THE INITIAL PRESSURE OF THE FIRST CONDENSER STAGE, AND ARE AT LEAST PARTIALLY EVAPORATED. ACCORDING TO THE INVENTION, AT LEAST A PARTIAL STREAM (19, 24) OF THE LIQUEFIED, PREVIOUSLY GASEOUS FRACTION OF THE COOLANT MIXTURE (15) IS AT LEAST TEMPORARILY EXPANDED (J, H) AND ADMIXED TO THE EXPANDED LIQUID FRACTION OF THE COOLANT MIXTURE (21).
