METHOD OF FILLING VEHICLE WITH NATURAL GAS AND MOVABLE GAS FILLING STATION Russian patent published in 2007 - IPC F17C5/06 F17D1/04 

FIELD: vehicle servicing.

SUBSTANCE: method comprises grouping the metallic high-pressure vessels, e.g. 40 MPa into first, second, and third sections of the unit for pressure accumulation with a pressure of 20 MPa, 25 MPa, and 40 MPa, respectively, analyzing gas by means of a gas analyzer, removing droplet moisture and mechanical admixtures from the gas by means of a filter-separator, and supplying the cleaned gas to one of the drying circuits. The second circuit is used for regenerating the driers. The natural gas is then supplied to the flow meter and to the first and subsequent compressor stages, is cooled in refrigerators, and cleaned in the water-oil separators downstream of each compressor stage. The natural gas compressed up to, e.g., 40 MPa is supplied to the high-pressure vessels. The vessels are emptied after the transporting until the pressure drops down to a minimum value required for filling it with the natural gas. After emptying, the natural gas is pumping to the metallic vehicle high pressure vessel until the consumer vessel is completely emptied. The pressure in the vessel is heightened up to the pressure required for the operation, and the vehicle vessel is connected with the vehicle supply system.

EFFECT: enhanced efficiency.
