Compressed Natural Gas Storage Tank

Compressed natural gas is very safe due to two important factors.

Compressed natural gas storage tank.

Special storage use and handling precautions are necessary in order to control these hazards. Perhaps the most rapidly growing application however involves the use of compressed natural gas cng natural gas that is compressed to less than 1 of the volume it occupies at standard atmospheric pressure as a fuel for private automobiles and fleet vehicles i e vehicles that log high daily mileage such as buses garbage trucks taxis and airport shuttles. Cng tanks come in 4 types. Home hanson news custom tanks asme miscellaneous pressure tanks vertical custom miscellaneous tanks compressed natural gas tanks mb685b.

The 48 inch inside diameter 33 5 cf spherical cng storage vessel is for the commercial dispensing of compressed natural gas to motor vehicles at cng fuel stations. The cylinder service pressure is rated at 3 600 psig with a 20 year service life. Instead natural gas is processed and stored at refinery plants and then pumped to households in the gas state through pipes. Hazards associated with compressed gases include oxygen displacement fires explosions and toxic gas exposures as well as the physical hazards associated with high pressure systems.

Many customers prefer cng because its combustion produces fewer undesirable gases than other traditional fuels. Once the tank is safely purged of any natural gas the expired cng tank must be rendered unusable and discarded. The physical properties of natural gas itself and the cng fuel system that is designed and built according to stringent quality standards. The capacity of each spherical vessel is 12 360 scf at 5 500 psi or 11 130 scf at 4 500 psi.

Compressed natural gas storage tanks commonly called cng these tanks house methane stored at high pressure typically used in place of petroleum diesel fuel or propane. Vertical cng storage tanks hanson pressure tanks finished projects mb 685 b 2400 gallon carbon steel cng tank 640 psig asme section viii div 1. The conformable tank stores high pressure compressed natural gas in the same place on a vehicle where gasoline is stored today yet still has enough gas to meet the desired driving range of the vehicle. Studies have shown an increase from 20 35 more cng in the same package envelope.

Our cng tanks are usdot fmvss 304 and ngv 2 compliant certified and tested to the highest standards. You could in principle store methane in a tank in the gas state but methane has such low density in the gas state that you could not store a usable amount. The vessel can supply cng at up to 5 500 psi to a fill up nozzle. The non cylindrical tank is called a conformable tank.
