Low temperature separation systems

Claim 1

A LOW TEMPERATURE SEPARATION SYSTEM FOR RECOVERING LIQUEFIABLE HYDROCARBONS FROM GASEOUS WELL STREAMS UNDER PRESSURE, INCLUDING, A LOW TEMPERATURE HYDROCARBON AND GAS SEPARATOR, A WELL STREAM INLET CONDUCTOR LEADING TO THE SEPARATOR MEANS IN THE INLET CONDUCTOR FOR COOLING THE WELL STREAM, THE LOW TEMPERATURE SEPARATOR ENCLOSING A COLD GAS ZONE AND A LIQUID HYDROCARBON ACCUMULATION ZONE, A COLD GAS OUTLET CONDUCTOR LEADING FROM THE SEPARATOR, A DESORBER VESSEL FOR STABILIZING THE SEPARATED LIQUID HYDROCARBONS, A LIQUID HYDROCARBON OUTLET CONDUCTOR LEADING FROM THE SEPARATOR TO THE DESORBER VESSEL A FIRST HEAT EXCHANGER HAVING ONE FLOW PATH CONNECTED INTO THE WELL STREAM INLET CONDUCTOR AND ANOTHER FLOW PATH CONNECTED INTO THE COLD GAS OUTLET, A COLD GAS BY-PASS CONDUCTOR CONNECTED INTO THE COLD GAS OUTLET CONDUCTOR ON BOTH SIDES OF THE FIRST HEAT EXCHANGER FOR BY-PASSING COLD GAS AROUND THE FIRST HEAT EXCHANGER, A SECOND HEAT EXCHANGER HAVING ONE FLOW PATH CONNECTED INTO THE COLD GAS OUTLET CONDUCTOR AND ANOTHER FLOW PATH CONNECTED INTO THE LIQUID HYDROCARBON OUTLET CONDUCTOR, A LIQUID HYDROCARBON BY-PASS CONDUCTOR CONNECTED INTO THE LIQUID HYDROCARBON OUTLET CONDUCTOR ON BOTH SIDES OF THE SECOND HEAT EXCHANGER BY BY-PASSING LIQUID HYDROCARBONS AROUND THE SECOND HEAT EXCHANGER, A THIRD HEAT EXCHANGER HAVING ONE FLOW PATH CONNECTED INTO THE COLD GAS BY-PASS CONDUCTOR AND ANOTHER FLOW PATH CONNECTED INTO THE LIQUID HYDROCARBON BY-PASS CONDUCTOR, AND VALVES FOR CONTROLLING FLOW THROUGH THE TWO-BY-PASS CONDUCTORS.
