Abstract: A method for obtaining a natural gas liquid (NGL) product from a liquefied natural gas (LNG) liquefaction facility including receiving a gas feed stream at an LNG facility having an NGL recovery unit integrated therein, cooling the gas feed stream via a demethanizer of the NGL recovery unit to separate a vapor from a liquid, transferring the vapor from the NGL recovery unit to an LNG liquefaction unit and transferring the liquid to a deethanizer within the NGL recovery unit for further cooling, and obtaining an ethane product and an NGL product from the cooled liquid.

Abstract: A method of constructing a plate fin heat exchanger includes joining a first side bar formed from a nickel-iron alloy to a first end of a fin element formed from a nickel-iron alloy through a first nickel-iron alloy bond, and joining a second side bar formed from a nickel-iron alloy to a second end of the fin element through a second nickel-iron alloy bond to create a first layer of the plate fin heat exchanger. The fin element defines a fluid passage.
