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.
Claims17
A method for obtaining a natural gas liquid (NGL) product from a liquefied natural gas (LNG) liquefaction facility, the method comprising:
- receiving a gas feed stream;
- cooling the gas feed stream to separate a vapor from a liquid, the gas feed stream cooled using a demethanizer, the vapor including at least light hydrocarbon components, the liquid including NGL components;
- transferring the vapor to an LNG liquefaction unit;
- transferring the liquid to a deethanizer;
- and
- obtaining an ethane product and an NGL product by cooling the liquid using the deethanizer.
