The lifting CNG gas station, developed by our company lately aiming for big cities, could completely solve many difficulties such as little land resource in big cities, few network coverage of gas station, big difficulty in construction of gas station, and so on, so to make use of gas cylinder trailer of 25MPa successfully may realize lifting CNG gas station system with non-secondary pressing, dynamic-free and circulating gas cylinder.
(1)The lifting CNG gas station system with circulating gas cylinder is the only suitable solution for network construction of gas station to big cities now, as well as the best practice scheme for energy saving and haze treatment to big cities.
(2)Simple easy to user operation, piping and equipment insulation performance is stable and reliable.
(3)Friendly man-machine interface, easy to use, low integration design and construction difficulty.
CNG gas station in the technical solution consists of gas dispenser and gas cylinder trailer of 25MPa, covering very small area, being a new kind of product after "compressor unit" and "hydraulic pressure" gas stations, which is unrestricted to gas displacement of compression equipment, with daily gas dispenser reaching over 100000 cubes according to quantity of gas dispenser, that could save input of some infrastructures such as three-phase dynamic power supply, pressing mechanical equipment, as well as free of mechanical wear and consumption of compact lubricating oil, so its operating cost is quite low, and it has become a station establishment mode with the highest cost performance at present. In the event that several LNG gas stations are established around big cities, it could obtain high-pressure gas fast in large amount, thus supply sufficient high-pressure air source of 25MPa for network of urban CNG gas station, with gas delivery amount of one gas cylinder trailer reaching over 8000 cubes, that could greatly save transport cost and be free from urban pipe network and pipeline gas.
