Abstract: Disclosed herein are systems and processes for removing heavies during the liquefaction of a natural gas. The processes include dissolving the heavies in the natural gas by adding external natural gas liquid (NGL), followed by a staged removal of the natural gas liquid (NGL) and dissolved heavies.

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.

Abstract: Systems and methods for processing liquefied natural gas (LNG) can include an LNG production system with a methane refrigeration cycle downstream from an ethylene refrigeration cycle. The methane refrigeration cycle can be a closed loop methane refrigeration cycle that maintains a methane refrigerant separate from a natural gas feed, (e.g., compared to an open loop methane refrigeration cycle that extracts the methane refrigerant from the natural gas feed and recombines the methane refrigerant with the natural gas feed). The natural gas feed can be a medium or high nitrogen gas feed having a nitrogen content greater than 1.0% molarity.

Abstract: Implementations described and claimed herein provide systems and methods for removing nitrogen during liquefaction of natural gas. In one implementation, a nitrogen rejection unit is used in an LNG facility to remove nitrogen from natural gas during an LNG liquefaction process. The nitrogen rejection unit contains at least two columns and at least one 3-stream condenser, 2-stream condenser or a two 2-stream condenser.
