Abstract
In a gas liquefaction plant that produces a liquefied gas by liquefying a raw gas, a pipe rack portion in which an air-cooling heat exchanging system is disposed has a rectangular shape when viewed from above. A first compressor, a precooling heat exchanging portion, an auxiliary heat exchanging portion, and a fourth compressor are arranged in this order along one long side of the pipe rack portion. A second compressor, a primary heat exchanging portion, and a third compressor are arranged in this order along the other long side of the pipe rack portion. A pipe that carries the raw gas cooled at the precooling heat exchanging portion is connected to the primary heat exchanging portion across the pipe rack portion. A pipe that carries a primary refrigerant compressed at the second and third compressors is connected to the auxiliary heat exchanging portion across the pipe rack portion.
