Abstract
A quench system for a refrigeration cycle of a liquefied natural gas (LNG) facility includes at least one compressor for compressing a refrigerant that cools a natural gas stream. Also included is a quench fluid supply structure containing a quench fluid. Further included is a cooler vessel and a quench fluid line extending from the quench fluid supply structure and through the cooler vessel for cooling therein, the quench fluid maintained in a liquid state through the entirety of the quench fluid line. Yet further included is a quench control valve disposed downstream of the cooler vessel to control a flow rate of the quench fluid routed therein. Also included is a refrigerant suction drum located downstream of the quench control valve and configured to receive the quench fluid from the quench fluid line, the refrigerant suction drum in fluid communication with at least one component for cooling.
