Compressed natural gas (CNG) is a fuel gas mainly composed of methane (CH 4), compressed to less than 1% of the volume it occupies at standard atmospheric pressure.It is stored and distributed in hard containers at a pressure of 20–25 megapascals (2,900–3,600 psi; 200–250 atm), usually in cylindrical or spherical shapes.
A Shell station near Lost Hills, California, US An IndianOil filling station near Dera Bassi in Punjab, India The majority of filling stations are built in a similar manner, with most of the fueling installation underground, pump machines in the forecourt and a point of service inside a building.
LCNG stations require less capital cost than fast-fill CNG stations alone but more than LNG stations. Aside from different fuel tanks, fuel metering, and computer modules, the engines in NG vehicles could be run by CNG or LNG without requiring any modification because both are forms of natural gas.
EKO – 80 stations in Quebec; Esso – supplies approximately 2000 stations across Canada owned by various companies that use the Esso name under license from Imperial Oil, which is majority-owned by Exxon; Federated Co-operatives [1] – Refine and supply 386 service stations in their network of independent co-operatives.
Typically three CNG tanks will be used, and a vehicle will first be fueled from one of them, which will result in an incomplete fill, perhaps to 2000 psig for a 3000 psig tank. The second and third tanks will bring the vehicle's tank closer to 3000 psi. The station normally has a compressor, which refills the station's tanks, using natural gas ...
There are two types of autogas equipment and autogas stations as well: LPG (propane-butane mix) and compressed natural gas (CNG, methane). Natural gas is stored at a higher pressure than LPG (200 bar vs. 10 bar for LPG). The main consumer of LPG is commercial light-weight cargo transport (so as GAZelles in Russia are mostly LPG-powered).
