Zusammenfassung:	METHOD AND PRODUCING LIQUEFIED NATURAL GAS (LNG) WHEREBY REFRIGERATION FOR COOLING AND LIQUEFACTION IS PROVIDED BY A MIXED REFRIGERANT SYSTEM PRECOOLED BY ANOTHER FRERIGERATION 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.
