Flexible Liquefied Natural Gas Plant

摘要

The present techniques are directed to a flexible liquefied natural gas (LNG) plant that may be tied to an external electric grid for importing or exporting electric power. Exemplary embodiments provide a method for producing LNG that includes producing a base load capacity of refrigeration capacity for LNG production from a first compression system. Electricity may be produced from a second compressor string if electricity is needed by an external power grid, or a second amount of refrigeration capacity may be provided by the second compressor string is natural gas feed is available and the external grid does not need power.

主权项

1. A method for producing liquefied natural gas (LNG), comprising:
producing a base load refrigeration capacity for LNG production from a first compression system; producing electricity from a second compression system; exporting the electricity to an external power grid when a demand for the amount of electricity exists at the external power grid; and producing a second load of refrigeration capacity from the second compression system when a demand for the electricity does not exist at the external power grid.
