摘要： PROBLEM TO BE SOLVED: To make it possible, when the rotary shaft of a swelling turbine is supported by a static pressure gas bearing, to stably supply a gas of pressure necessary for supporting the rotary shaft to the bearing without providing a dedicated compressor to a line which supplies the gas to the bearing.SOLUTION: A liquefaction system 100 includes: a feed line 3 which feeds a liquefaction raw material gas from a liquefaction raw material supply source 1 so that the pressure of a liquefaction raw material gas is maintained at a predetermined pressure P0 or above at the predetermined parts 3b and 3c; a refrigerant circulation line 5 for circulating a refrigerant; a static pressure gas bearing GB which rotatably bears the rotary shafts of the swelling turbines 14H and 14L when the gas of a predetermined pressure P0 or above is supplied; and a bearing supply line 7 which connect the predetermined parts 3b and 3c of the feed line 3 to the gas import 49 of the static pressure gas bearing GB so that the gas is supplied to the static pressure gas bearing GB.
