Abstract
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.
Claims5
A method for producing liquefied natural gas (LNG) in a flexible LNG plant having first and second compression systems arranged in parallel, comprising:
- producing a base load of refrigeration capacity for LNG production from the first compression system;
- when a demand for electricity exists at an external power grid, producing the electricity from the second compression system and exporting the electricity to the external power grid;
- and
- when the demand for electricity does not exist at the external power grid, producing a second load of refrigeration capacity for LNG production from the second compression system.
