METHOD OF REALIZATION OF NATURAL GAS AND MOBILE GAS CHARGING UNIT FOR THIS METHOD Russian patent published in 1999 - IPC

FIELD: preparation of gas followed by transfer of gas under pressure to User's reservoirs and to mobile distributing units. SUBSTANCE: method includes gas preparation stages and transfer of gas under pressure to User's reservoirs. At the preparation stage, low-pressure gas is fed to compressing reservoir where compression is effected through pumping liquid into this reservoir, thus delivering gas to accumulating reservoir where gas is dried. At the stage of transfer of gas to User's reservoirs pressure in the accumulating reservoir shall be checked to exclude its drop below permissible minimum level; to this end, liquid shall be pumped into accumulating reservoir. Mobile gas charging unit includes platform with high-pressure gas reservoir, charging manifold connected with gas receiving and dispensing units and with each reservoir, compressor equipped with hydraulic pump and at least one high-pressure reservoir. Inlet of hydraulic pump is connected with working liquid tank and outlet is connected with lower portion of each reservoir y means of pressure main through hydraulic lock and pipe line. Hydraulic lock is connected with inlet of hydraulic pump by means of return main. Return and pressure mains are fitted with hydraulically-controlled differential valves connected with common with common hydraulic distributor for operation of valves in anti-phase. Each reservoir is provided with high and low level sensors demonstrating the level of liquid fed from pressure main. EFFECT: reduced power requirements. 16 cl, 1 dwg
