Abstract

A natural gas liquefaction equipment that can cope with locational conditions where seawater, river water or the like cannot be utilized and without being influenced by changing of atmospheric air temperature dependent upon time and season, can hold constant the volume of liquefied natural gas produced throughout the year. The natural gas liquefaction equipment comprises not only first refrigeration cycle line (50) including, for example, mixed refrigerant compressing low-pressure-stage refrigerant compressor (23) and high-pressure-stage refrigerant compressor (24), compressed mixed refrigerant cooling intermediate cooling means (25) and postposed cooling means (26), mixed refrigerant further cooling secondary cooling means (19), cooled mixed refrigerant expanding expansion means and a main heat exchanger capable of heat exchanging with expanded mixed refrigerant to thereby cool natural gas but also second refrigeration cycle line (51) capable of producing a cold heat source for use in the secondary cooling means (19) with the use of, for example, propane refrigerant as working fluid, and further comprises third refrigeration cycle line (52) capable of producing a portion of cold heat source for use in the intermediate cooling means (25) and postposed cooling means (26) with the use of, for example, propane refrigerant as working fluid.
