Abstract

A natural gas liquefaction apparatus according to the present invention comprises: a cryogenic heat exchanger in which a natural gas is liquefied into LNG by exchanging heat with a first and a second refrigerant while the natural gas passes through the cryogenic heat exchanger; a first refrigerant cycle which allows the first refrigerant to circulate therethrough, includes a partial flow channel passing through the cryogenic heat exchanger for heat exchange, and includes multiple divided flow channels in which the first refrigerant expands and is pre-compressed after exchanging heat in the cryogenic heat exchanger; and a second refrigerant cycle which allows the second refrigerant to circulate therethrough and includes a partial flow channel passing through the cryogenic heat exchanger.
