Natural gas liquefying apparatus

A natural gas liquefying apparatus for liquefying natural gas, comprising:

• a cooling region in which a precooling unit and a liquefaction unit are arranged, the precooling unit including a precooling heat exchanger configured to precool, through use of a precooling refrigerant, the natural gas supplied to the natural gas liquefying apparatus, the liquefaction unit including a heat exchanger for liquefaction configured to liquefy the precooled natural gas through use of a liquefying refrigerant;
• a compression region in which a first compressor and a second compressor are arranged, the first compressor being configured to compress the precooling refrigerant vaporized by the precooling heat exchanger, the second compressor being configured to compress the liquefying refrigerant vaporized by the heat exchanger for liquefaction;
• a first refrigerant cooler group arrangement region in which an air-cooled cooler group configured to cool the precooling refrigerant compressed by the first compressor is arrayed and arranged so as to have a rectangular shape having a long side and a short side in top view;
• and
• a second refrigerant cooler group arrangement region in which an air-cooled cooler group configured to cool the liquefying refrigerant compressed by the second compressor is arrayed and arranged so as to have a rectangular shape having a long side and a short side in top view,
• wherein at least a part of the cooling region and at least a part of the compression region are arranged so as to be opposed to each other across the long side of the rectangular shape of the second refrigerant cooler group arrangement region, and
• wherein the first refrigerant cooler group arrangement region is arranged so that the long side of the first refrigerant cooler group arrangement region is opposed to one side of a rectangular region including the compression region, the one side being different from a side of the rectangular region opposed to the long side of the second refrigerant cooler group arrangement region.
