    Abstract: Methods and apparatuses for liquefying hydrocarbon streams are provided. In one embodiment, a method for liquefying a hydrocarbon stream includes expanding the hydrocarbon stream with a turbo expander to form an expanded hydrocarbon stream. The method includes compressing a first refrigerant with the turbo expander. Further, the method includes cooling the expanded hydrocarbon stream with the first refrigerant to form a liquid hydrocarbon stream.

    Abstract: A process for liquefying natural gas by; a) causing it to flow through three series connected heat exchangers, where gas is cooled to T3; T3 is less/equal to the liquefaction temperature of natural gas at atmospheric pressure; and b) causing the closed circuit circulation of a first stream of refrigerant gas at a pressure P1 lower than P3 entering the third exchanger and leaving the first exchanger, the first stream obtained using a first expander to expand a first portion of a second stream at P3 higher than P2, the second stream flowing relative to the natural gas stream entering the first exchanger and leaving the second exchanger; and a third stream at a pressure P2 higher than P1 and lower than P3 flowing relative to the first stream, entering the second exchanger and leaving the first exchanger; c) the second stream at the pressure P3 obtained by compression.

    Abstract: A compressor starting torque converter method and apparatus for high power rotating equipment strings includes a compressor starting torque converter (CSTC) (16) and gearing to make the input and output speed conform to the speed and power requirements of the at least one compressor (4) at the end of the string. The string also includes a prime mover (10), either a motor or gas turbine with a starter motor. The CSTC is driven by a prime mover that has been geared down (via 18) to an appropriate speed for efficient power transfer, followed by a gear increasing unit (20) to allow the output of the CSTC to be increased to conform to the necessary requirements of a high speed compressor. The gearing can be two separate units with their own housings, or incorporated in a single housing with the CSTC. The CSTC may be a CSTC used in pressurized starts high compressor load strings for LNG refrigeration service.

    Abstract: Normal operation of an oxygen liquefaction system (100) may be established responsive to a deviation in current supplied thereto. Current being supplied to a compressor (118) included in the oxygen liquefaction system may be monitored. The compressor may be deactivated responsive to commencement of a current level deviation event in the monitored current. The compressor may be energized responsive to cessation of the current level deviation event in the monitored current. Performance characteristics of the oxygen liquefaction system may be identified.
