    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: A system for liquefying natural gas that includes a process and apparatus for enhancing the performance of one or more gas turbines. Gas turbine power output can be stabilized or even enhanced using the interstage cooling system configured according to one or more embodiments of the present invention. In one embodiment, partially compressed air from a lower compression stage of a gas turbine is cooled via indirect heat exchange with a primary coolant before being returned to a higher compression stage of the same gas turbine. Optionally, the interstage cooling system can employ one or more secondary coolants to remove the rejected heat from the primary coolant system.

    Abstract: A semi-closed loop system for producing liquefied natural gas (LNG) that combines certain advantages of closed-loop systems with certain advantages of open-loop systems to provide a more efficient and effective hybrid system. In the semi-closed loop system, the final methane refrigeration cycle provides significant cooling of the natural gas stream via indirect heat transfer, as opposed to expansion-type cooling. A minor portion of the LNG product from the methane refrigeration cycle is used as make-up refrigerant in the methane refrigeration cycle. A pressurized portion of the refrigerant from the methane refrigeration cycle is employed as fuel gas. Excess refrigerant from the methane refrigeration cycle can be recombined with the processed natural gas stream, rather than flared.
