SYSTEM AND METHOD OF LIQUEFIED NATURAL GAS FILLING OF MOTOR VEHICLES Russian patent published in 2020 - IPC F17C6/00 F17C13/02 

FIELD: oil, gas and coke-chemical industries.

SUBSTANCE: group of inventions relates to fuelling vehicles using liquefied natural gas as motor fuel. LNG corking vehicle filling system includes a filling column equipped with inlet and drain pipelines. LNG feed line to the crib is equipped with the first flow meter, the first temperature sensor, the supply valve and the pressure sensor installed in series in the LNG feed direction. Drain line for return of vapours contains second temperature sensor, second flow meter and drain line valve connected to the vapour return pipeline in series installed along the steam return line to the reservoir. Filling column is equipped with a bypass pipeline connected to the LNG supply line by two bypass lines equipped with valves, the first of which is installed at the input of the first flow meter of the LNG supply line, and the second one is located at the outlet of the first LNG supply line temperature sensor.

EFFECT: technical result consists in improvement of operational capabilities of the declared system and method of refilling LNG vehicles, as well as reduction of gas emissions and simplification of the filling process.
