Abstract: By using the power generated by an expander by an expansion of material gas, the outlet pressure of a compressor is increased, and a requirement on the cooling capacity of a cooler is reduced. The liquefaction system (1) for natural gas comprises a first expander (3) for generating power by using natural gas under pressure as material gas; a first cooling unit (11, 12) for cooling the material gas depressurized by expansion in the first expander; a distillation unit (15) for reducing or eliminating a heavy component in the material gas by distilling the material gas cooled by the first cooling unit; a first compressor (4) for compressing the material gas from which the heavy component was reduced or eliminated by the distillation unit by using power generated in the first expander; and a liquefaction unit (21) for liquefying the material gas compressed by the first compressor by exchanging heat with a refrigerant.

Abstract: Apparatus for compressing gaseous refrigerant for use in a refrigeration circuit of a liquefaction plant comprises a refrigeration circuit (1) and two compressors (10, 20) that are functionally connected to the refrigeration circuit. One of the compressors is provided with a double suction configuration, and the outlets and the inlets of the first and second compressors are connected at least partly in a mutually parallel flow configuration such that the refrigerant flow that leaves the refrigeration circuit from a plurality of outlets thereof is distributed between the two compressors before joining at the inlet of the refrigeration circuit.

Abstract: [Problem] To suppress excessive increases in the temperature of a raw material gas that is introduced to a liquefying device after being compressed by a compressor and thereby to easily adjust the temperature level of the raw material gas such that said temperature level nears the temperature level of the site where the gas is introduced to the liquefying device. [Solution] A natural gas liquefying system (1) that is characterized by being provided with: a first expander (3) that expands a raw material gas that is a natural gas obtained by pressurization; first coolers (10, 11, 12) that cool the raw material gas; a distilling device (15) that distills the raw material gas that is cooled by the first coolers and thereby reduces or eliminates the heavy components of the raw material gas; a first compressor (4) into which is introduced an overhead distillate from which the heavy components of the raw material gas have been reduced or eliminated in the distilling device; and a liquefying device (21) that liquefies, by means of a heat exchange with a coolant, the gaseous phase component that is separated from a compressed gas that is compressed in the first compressor.

Abstract: [Problem] To use the motive power generated in an expander by means of the expansion of a raw material gas to increase the discharge pressure of a compressor, and to decrease the cooling power required of a cooler. [Solution] A natural gas liquefying system (1) that is characterized by being provided with: a first expander (3) that generates motive power by expanding a raw material gas that is a natural gas obtained by pressurization; first coolers (11, 12) that cool the raw material gas that is decompressed by expansion in the first expander; a distilling device (15) that distills the raw material gas that is cooled by the first coolers and thereby reduces or eliminates the heavy components of the raw material gas; a first compressor (4) that uses the motive force generated in the first expander to compress the raw material gas from which the heavy components are reduced or eliminated in the distilling device; and a liquefying device (21) that liquefies, by means of a heat exchange with a coolant, the raw material gas that is compressed by the first compressor.
