Devices, systems, facilities, and processes for liquefied natural gas production

A liquefied natural gas (LNG) production facility comprising:

• an acid gas removal unit configured to accept raw feed natural gas and to generate an acid gas stream, a flash gas stream, and a purified natural gas stream, wherein the acid gas stream is directable to a sequestration compression unit;
• a heavies removal unit configured to receive a dry purified natural gas stream from a dehydration unit and to produce a liquid condensate product and a vapor product;
• a condensation storage tank configured to receive the liquid condensate product from the heavies removal unit, and to allow for the venting of boil off gas (BOG);
• a liquefaction unit that condenses natural gas vapor into liquefied natural gas;
• a gas turbine;
• an on-site hydrogen generation unit that provides hydrogen to the gas turbine, wherein the hydrogen generation unit is a steam reformer;
• at least one capture unit that generates a CO2-rich stream from products of the steam reformer;
• the sequestration compression unit configured to compress and convey at least one CO2-rich stream from a capture unit, towards a sequestration site, thereby reducing the overall emissions from the LNG facility;
• an LNG storage tank configured to receive and store LNG from the liquefaction unit, and to allow for the venting of BOG;
• and
• an LNG loading facility configured to receive LNG from the LNG storage tank and to transfer LNG to a marine vessel comprising a marine LNG storage tank, the LNG loading facility further configured to allow for the venting of BOG,
• wherein BOG from at least one of the condensation storage tank, the LNG storage tank, and the LNG loading facility is directable as feed to the steam reformer;
• and
• wherein a fuel to the gas turbine contains at least about 90% hydrogen by volume.
