Abstract: A system for natural gas liquefaction includes a natural gas source for providing a flow of natural gas and a moisture removal system located downstream of the natural gas source. The system includes a first heat exchanger located downstream of the moisture removal system for exchanging heat between the natural gas flow path and a first refrigerant flow path of a refrigerant cycle subsystem. The system includes one first throttle valve located downstream of heat exchanger for expanding the flow of natural gas and causing reduction in pressure and temperature of the flow of natural gas. The system includes a filter subassembly for separating solid particles present in the flow of natural gas. The system includes a second heat exchanger located downstream of the filter subassembly and is configured to transfer heat from a natural gas vapor flow path to a second refrigerant flow path of the refrigeration cycle subsystem.

Abstract: A system and method for producing liquid natural gas (LNG) from a natural gas stream is presented. The system includes a moisture removal device and compressor for removing moisture from and compressing the natural gas stream. The low moisture compressed natural gas stream is cooled in a heat exchanger to discharge a cooled compressed discharge stream. A multi-phase turbo expander provides for further cooling and expansion of the cooled compressed discharge stream, generating an expanded exhaust stream comprising a mixture of a vapor comprised substantially of CH4 and a LNG/ice/solid CO2 slurry. The expanded exhaust stream is separated to generate a vapor stream comprised substantially of CH4 and a liquid natural gas/ice/solid CO2 slurry stream. Further separation of the liquid natural gas/ice/solid CO2 slurry stream generates a liquid natural gas output stream and an output stream comprised substantially of ice/solid CO2.

Abstract: PROBLEM TO BE SOLVED: To provide an improved water removing pocket to provide improved water removing efficiency. SOLUTION: In the constitution of the improved water removing pocket including the axially expanded section of the water removing slot covering a bucket cover, the pocket can provide a desired slot expansion section by omitting a trough segment upperstream of the pocket. The constitution of the improved water removing pocket relating to the present invention improves water removing efficiency by making the water move along the outside side wall of a nozzle in a membrane state and accompanied by the leaked jet stream above the bucket cover and enter the pocket.

Abstract: A supersonic compressor rotor that includes a rotor disk that includes a substantially cylindrical endwall, a radially inner surface, and a radially outer surface. The endwall extends between the radially inner surface and the radially outer surface. A plurality of vanes are coupled to the endwall. The vanes extend outwardly from the endwall. Adjacent vanes form a pair and are spaced a circumferential distance apart such that a flow channel is defined between each pair of circumferentially-adjacent vanes. The flow channel extends generally radially between an inlet opening and an outlet opening. A first supersonic compression ramp is coupled to the endwall. The first supersonic compression ramp is positioned within the flow channel to facilitate forming at least one compression wave within the flow channel.
