LIQUEFIED GAS PRODUCTION FACILITY

摘要

Provided is a liquefied gas production facility having multiple liquefied gas production units that produce liquefied gas by liquefying a supply gas for which undesired material has been removed, resulting in a main component of methane, the liquefied gas production facility being characterized in that: each of the liquefied gas production units has a heat exchanger that cools the supply gas by exchanging heat between the supply gas and a refrigerant, a compressor that compresses the refrigerant evaporated by the exchange of heat with the supply gas, an air fin cooler unit that cools the compressed refrigerant, and an expansion unit that cools the cooled refrigerant by means of adiabatic expansion; the air fin cooler unit has multiple air fin coolers, with the air fin coolers being arranged in at least one straight line, thus forming in their entirety a first rectangular shape; the heat exchangers, compressors, and expansion units of the liquefied gas production units are arranged respectively at the side in the lengthwise direction of the first rectangular shape of the air fin cooler unit, thus forming in their entirety a second rectangular shape; and when each two adjacent liquefied gas production units of all of the multiple liquefied gas production units are designated respectively as a first and a second liquefied production unit, the first and second liquefied gas production units are arranged so as to be staggered in the lengthwise direction of the second rectangular shape.
