Abstract
Devices, systems, and methods for liquefied natural gas production facilities are disclosed herein. A liquefied natural gas (LNG) production facility includes a liquefaction unit that condenses natural gas vapor into liquefied natural gas; an electric-driven compression system for the refrigerant(s) in power to the liquefaction unit; and a sequestration compression unit configured to compress and convey at least one CO2-rich stream towards a sequestration site, thereby reducing the overall emissions from the LNG facility.
Claims24
A liquefied natural gas (LNG) facility comprising:
- an acid gas removal unit configured to process a feed natural gas and generate an acid gas stream, a flash gas stream, and a purified natural gas stream, the LNG facility being configured to direct the acid gas stream to a sequestration compression unit;
- a liquefaction unit configured to condense a natural gas stream into an LNG;
- and
- the sequestration compression unit configured to compress a CO2-rich stream and convey the compressed CO2-rich stream towards a sequestration site, the CO2-rich stream comprising the acid gas stream.
A process of producing a liquefied natural gas (LNG) in an LNG facility comprising an acid gas removal unit configured to process a feed natural gas and generate an acid gas stream, a flash gas stream, and a purified natural gas stream, the LNG facility being configured to direct the acid gas stream to a sequestration compression unit;
- a liquefaction unit configured to condense a natural gas stream into the LNG;
- and the sequestration compression unit configured to compress a CO2-rich stream and convey the compressed CO2-rich stream towards a sequestration site, the CO2-rich stream comprising the acid gas stream, the process comprising:
- processing the feed natural gas and generating the acid gas stream, the flash gas stream, and the purified natural gas stream by the acid gas removal unit;
- condensing the natural gas stream into the LNG by the liquefaction unit;
- and
- compressing the CO2-rich stream and conveying the compressed CO2-rich stream towards the sequestration site by the sequestration compression unit.
