GASVERFLÜSSIGUNGSVERFAHREN DURCH PARTIEL KONDENSATION VON GEMISCHTEM KÄLTEMITTEL BEI ZWISCHENGELAGERTEN TEMPERATUREN |
摘要 |
Method of producing liquefied natural gas (LNG) whereby refrigeration for cooling and liquefaction is provided by a mixed refrigerant system precooled by another refrigeration system. At least one liquid stream is derived from the partial condensation and separation of the mixed refrigerant at a temperature higher than the lowest temperature provided by the precooling system when the mixed refrigerant is condensed at a final highest pressure. When the mixed refrigerant is condensed at a pressure lower than the final highest pressure, condensation is effected at a temperatures equal to higher than the lowest temperature provided by the precooling system. The mixed refrigerant liquid is used to provide refrigeration at a temperature lower than that provided by the precooling system. <IMAGE> |
