INTEGRATED METHOD FOR PRODUCTION AND TRANSPORTATION OF LIQUEFIED NATURAL GAS Russian patent published in 2023 - IPC F25J1/00 F17C3/02 F17C9/02 

FIELD: fuel and energy complex.

SUBSTANCE: invention relates to the fuel and energy complex and can be used in energy and gas supply systems in the absence of main gas transport. The integrated method for the production and transportation of liquefied natural gas (LNG) is that LNG is drained from the transport tank through the receiving device into the storage tank, fed to the evaporator, where it is converted into a vapor phase, then heated, odorized and fed to consumers through the reduction point. LNG is transported in a cryogenic tank, inside which a vessel for transporting gas is placed. Between the main shell and the vessel for transporting gas, an additional shell is installed and fixed, and the space between the main and additional shells is used to transport a refrigerant that maintains a negative temperature in the tank. The space between the additional shell and the vessel is filled with a low density insulating material. LNG regasification takes place in a heat exchanger, the heating medium of which is the refrigerant transported in a cryogenic tank. Pre-cooling of natural gas is carried out in a heat exchanger with a refrigerant in the cooling circuit.

EFFECT: increase in thermodynamic efficiency and simplification of technology and equipment.
