Abstract: A METHOD FOR SUB-COOLING NORMALLY GASEOUS HYDROCARBON MIXTURES PRODUCED IN A CRYOGENIC PROCESS UNIT WHEREIN THE MIXTURE IS INTRODUCED TO A GAS/LIQUID SEPARATOR, WHICH MAY BE A STORAGE VESSEL, AND VAPOR CONTAINING AT LEAST TWO COMPONENTS OF THE MIXTURE IS RECOVERED AS REFRIGERANT, EMPLOYED IN AN OPEN CYCLE REFRIGERATION SYSTEM TO SUB-COOL THE HYDROCARBON MIXTURE, AND RETURNED TO THE SEPARATOR. THE SYSTEM IS PARTICULARLY USEFUL FOR SUB-COOLING A HYDROCARBON PRODUCT STREAM WHILE, AT THE SAME TIME, RECOVERING BOIL-OFF VAPOR FROM A CRYOGENIC STORAGE VESSEL. (FIG.1)
