PROBLEM TO BE SOLVED: To provide a gas liquefying plant allowing reduction of a height of a pipe rack to solve a problem of strength of the pipe rack, allowing reduction of construction cost, and allowing solving problems of pressure loss and heat loss of a refrigerant. SOLUTION: This gas liquefying plant 1 has: a precooling heat exchanger 4 auxiliarily cooling supply gas by a first refrigerant, and auxiliarily cooling a second refrigerant by the first refrigerant; a first refrigerant compressor 5 compressing the first refrigerant, and cooling it and sending it to the precooling heat exchanger 4; a cryogenic heat exchanger 7 cooling and liquefying the supply gas by the second refrigerant; a second refrigerant compressor 8 compressing the second refrigerant, and sending it to the cryogenic heat exchanger 7; and a pipe collection part 11 for placing pipes 10. The precooling heat exchanger 4, the first refrigerant compressor 5, the cryogenic heat exchanger 7, and the second refrigerant compressor 8 are disposed on one side 16 of the pipe collection part.
