Document Type and Number:
WIPO Patent Application WO/2021/084621
Kind Code:
A1
Abstract:
[Problem] To provide a natural gas liquefier for which the amount of materials used and the amount of construction work are reduced. [Solution] This natural gas liquefier is provided with: a pre-cooling unit 2 that is a processing unit which pre-cools natural gas; a liquefaction unit 3 that is a processing unit which liquefies the natural gas; a refrigerant cooling unit 8 that is a processing unit which cools a refrigerant used for the liquefaction; a compression unit 9 that includes compressors 91 and 92 which compress each vaporized refrigerant; and pipe racks 10 that have a rectangular shape in a view from above, that each hold pipes 201, and that have respective upper surfaces on which air-cooled coolers 100 are disposed so as to be aligned. A first disposition region 7A and a second disposition region 7B, in which the processing units are disposed separately from the compression unit 9, are positioned opposite to each other so as to sandwich the long sides of the pipe racks 10. At the sandwiched parts of the pipe racks 10, a region 101 in which no air-cooled coolers 100 are disposed is provided so that a plurality of pipes 201a, through which various refrigerants flow, are disposed so as to extend along the short-side direction of the pipe racks 10.
