Liquefier system

摘要

A liquefier system (100) comprises: a feed line (3) that feeds a raw material gas from a raw material supply source (1) such that the pressure of the raw material gas is maintained at at least a prescribed pressure (PO) in prescribed sections (3b, 3c); a refrigerant circulation line (5) for circulating a refrigerant; a static-pressure gas bearing (GB) that receives supply of a gas of at least the prescribed pressure (PO) and rotatably supports a rotating shaft (22) for expansion turbines (14H, 14L); and a bearing supply line (7) that connects the prescribed sections (3b, 3c) of the feed line (3) and a gas inlet (49) for the static-pressure gas bearing (GB), in order to supply gas to the static-pressure gas bearing (GB).
