ABSTRACT:
A method and apparatus are disclosed for increasing the production of liquid natural gas and conserving energy and reducing vapor production, while reducing equipment cost, in a liquid natural gas manufacturing installation. A liquid gas stream from a main exchanger is fed to a bi-phase rotary separator, which separates a vapor phase from the liquid phase without requiring an expansion valve and flash device, or liquid pump, as is commonly used. Optionally, work can also be extracted from the stream by the separator.
