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 ]
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 bar), usually in cylindrical or spherical shapes.
One GGE of CNG pressurized at 2,400 psi (17 MPa) is 0.77 cubic feet (22 litres; 5.8 US gallons). This volume of CNG at 2,400 psi has the same energy content as one US gallon of gasoline (based on lower heating values: 148,144 BTU/cu ft (1,533.25 kWh/m 3 ) of CNG and 114,000 BTU/US gal (8.8 kWh/L) of gasoline.

It is possible to mix the ANG and CNG technology to reach an increased capacity of natural gas storage. In this process known as high pressure ANG, a high pressure CNG tank is filled by absorbers such as activated carbon (which is an adsorbent with high surface area) and stores natural gas by both CNG and ANG mechanisms.
Locomotives are classified by track gauge, motive power, function, power rating and model in a four- or five-letter code. [21] The locomotives may be Longer Hood Front (LHF), where the driver cabin is behind the hood of the engine or Short Hood Front (SHF), where the cabin is located towards the front.
Refineries in India processed 221.37 Mt of oil in 2020-21 achieving a capacity utilization of 88.8%. With a total refining capacity of 69.23 million metric ton per year, the state-owned Indian Oil Corporation was the largest refiner in the country by capacity. Indian Oil's refineries processed 62.35 Mt of crude oil in 2020–21.
