摘要： There is provided a system and method for producing liquefied natural gas (LNG). An exemplary method includes flowing a high-pressure stream of LNG through a first series of liquid turbines. The exemplary method also includes generating electricity by reducing the pressure of the high-pressure stream of LNG to form a low-pressure stream of LNG. The exemplary method additionally includes bypassing any one the liquid turbines that has a failure while continuing to produce electricity from the first series.

摘要： 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.
