Compressed natural gas vehicles require a greater amount of space for fuel storage than conventional petrol-powered vehicles. Since it is a compressed gas, rather than a liquid like petrol, CNG takes up more space for each GGE (petrol gallon equivalent). However, the cylinders used to store the CNG take up space in the trunk of a car or bed of ...
A natural-gas processing plant in Aderklaa, Austria. Natural-gas processing is a range of industrial processes designed to purify raw natural gas by removing contaminants such as solids, water, carbon dioxide (CO 2), hydrogen sulfide (H 2 S), mercury and higher molecular mass hydrocarbons to produce pipeline quality dry natural gas [1] for pipeline distribution and final use. [2]
A cascade filling system is a high-pressure gas cylinder storage system that is used for the refilling of smaller compressed gas cylinders. [1] [2] In some applications, each of the large cylinders is filled by a compressor, otherwise they may be filled remotely and replaced when the pressure is too low for effective transfer. The cascade ...
Because natural gas emits less smog-forming pollutants than other fossil fuels when combusted, cleaner air has been measured in urban localities switching to natural gas vehicles. [64] Tailpipe CO 2 can be reduced by 15–25% compared to gasoline, diesel. [65] The greatest reductions occur in medium and heavy duty, light duty and refuse truck ...
Natural gas is also used in the manufacture of fabrics, glass, steel, plastics, paint, synthetic oil, and other products. [103] Fuel for industrial heating and desiccation processes. Raw material for large-scale fuel production using gas-to-liquid (GTL) process (e.g. to produce sulphur-and aromatic-free diesel with low-emission combustion).
Compressed natural gas (CNG) carrier ships are those designed for transportation of natural gas under high pressure. [1] CNG carrier technology relies on high pressure, typically over 250 bar (2900 psi ), to increase the density of the gas, but it is still 2.4 times less than that of LNG (426 kg/m 3 ). [ 2 ]
The depleted reservoir formation should be readily capable of holding sufficient volumes of injected natural gas in the pore space between grains (via high porosity), of storing and delivering natural gas at sufficient economic rates (via high permeability) and be contained so that natural gas cannot migrate into other formations and be lost ...
Gas separator membrane skid used in membrane separation process to extract carbon dioxide [15] Landfill gas can be converted to high-Btu gas by reducing its carbon dioxide, nitrogen, and oxygen content. The high-Btu gas can be piped into existing natural gas pipelines or in the form of CNG (compressed natural gas) or LNG (liquid natural gas ...
