Liquefied natural gas (LNG) plant has relaxation gas line that is extended from relaxation drum to relaxation gas unit and is isolated from gas liquefaction plant to conduct relaxation gas to relaxation gas unit

摘要

The LNG plant (LNGP) has flash drum (FD) in gas liquefaction plant (GLP) to change high pressure gaseous natural gas (GNG) to low pressure liquid natural gas (LNG) such that the relaxation gas (EFG) consisting of gas remaining portions of the expanded gaseous natural gas is obtained. A flash gas unit conveys relaxation gas from the flash drum to fuel unit (FGU). A relaxation gas line (EFGL) is extended from relaxation drum to relaxation gas unit and is isolated from gas liquefaction plant to conduct relaxation gas to the relaxation gas unit. An independent claim is included for method for operation of LNG plant.
