METHOD FOR TURNDOWN OF A LIQUEFIED NATURAL GAS (LNG) PLANT
First Claim
1. A method for turndown of a liquefied natural gas (LNG) plant, the plant including a liquefaction unit arranged in a flow path of the plant, wherein the method comprises:
- removing LNG from a first location in the flow path downstream of the liquefaction unit;
vaporizing the removed LNG, or heating the removed LNG so that the removed LNG is transformed to gas phase; and
re-admitting the vaporized or transformed LNG to the flow path at a second location upstream of the liquefaction unit.
