TECHNOLOGIES
- A low-tonnage LNG plant is installed in close proximity to the gas field
- Produced LNG is transported from the plant to the storage and regasification park
- Optionally, it is proposed to install its own gas genset power plant to produce low-cost electricity for its own needs, as well as for the domestic and industrial needs of third parties located nearby.
General scheme of LNG production (option):
- The raw gas (NG) coming from the treatment unit is cooled in refrigerators. Propane is used at different pressure levels in each of the refrigerators (TO-1..TO-3), allowing the raw gas to cool to a temperature of about – 35 C.
- Pre-cooled natural gas and separated in the separator (E-1) from heavy hydrocarbons is fed into the main cryogenic heat exchanger (TO-4), where it is further cooled, liquefied and supercooled in the warm and cold sections of the heat exchanger, after which the gas enters the instantaneous evaporation tank.

Prospects for the development of low-tonnage LNG projects
Today in Russia there are 11 low-tonnage plants for the production of liquefied natural gas with a total capacity of about 100 thousand tons. It is planned to increase the capacity of small LNG plants 4 times by 2025 to more than 400 thousand tons per year. This follows from the Roadmap for the development of the low-tonnage LNG market, which was approved by the Government of the Russian Federation. It is also planned to expand the use of LNG as a fuel for transport. Primarily, for agricultural and road building equipment, as well as road, rail and water transport.Development plan for low-tonnage LNG production and gas refuel infrastructure at LNG
