Rawmatt CNG


Compressed Natural Gas (methane stored at high pressure) is an alternative fuel, which is economical, emits less noxious gases, and is thus a viable replacement for gasoline, diesel fuel, and propane/LPG. Being lighter than air, it disperses quickly when discharged, posing a minimum risk in case of a spill.


CNG is manufactured by compressing natural gas (primarily, methane) to less than 1% of the volume it occupies at standard atmospheric pressure. It is stored and distributed in stronger and thicker containers, usually of cylindrical or spherical shapes, at a pressure of 20–25 MPa (2,900–3,600 psi).


CNG is widely used in Auto rickshaws, Cars & Buses. For use in Automobiles as fuel, it is compressed to a pressure of 200-250 bar to enhance the vehicle on-board storage capacity. CNG or Compressed Natural Gas is a fossil fuel substitute for petrol, diesel, or LPG.


From reduced exhaust emissions to reduced energy costs, CNG offers a range of sustainable, safer, economical, and empowering solutions against conventional fuels and petroleum products. Here are its 6 major benefits that make it the best alternative fuel in the industry today.

What is CNG


CNG has the lowest content of carbon and other pollutants. As a result, it releases 20-30% fewer greenhouse gas emissions, 95% fewer tailpipe emissions, and 0% evaporative emissions. Ergo, the cleanest and odorless transportation fuel.


CNG storage tanks come with a tight seal, which reduces the possibility of an explosion. As it releases little to no emissions while refueling or in the event of a spill, in fact quickly dissipating instead of contaminating or harming anything in its proximity, it is both physically and environmentally safer.


CNG has an octane rating of about 130, which makes it superior to petroleum-based products. It knocks less, exhibits no vapor locking, gives the engine a better start, and enhances the vehicle’s mileage. This performance advantage is also why CNG is considered a desirable fuel.


CNG has zero lead and is non-corrosive, nondilutive, and noncontaminating. This helps in sustaining the life of engines, giving you more time between regular tune-ups and maintenance. As this dramatically reduces your general overhead and fleet costs, CNG proves out to be more cost-effective than gasoline and diesel.


CNG is an abundant fuel. As it can be produced domestically using our very own natural resources, it cuts short our reliance on imported oil, creates jobs, and boosts the local economy


CNG’s efficiency, safety, abundance, and cost-effectiveness make it the fuel for all reasons – the fuel of choice for the future.  In fact, 12 million vehicles are already powered by natural gas throughout the world and more companies and municipalities are joining every day. This will not only help the environment but also the economy.


Far from gas fields, pipelines are too impractical and costly to build. This difficulty can be evaded by cooling gas to make a liquid, thus compressing its volume for easier, safer storage, and shipping overseas.

Rawmatt has been a pioneer in liquefied natural gas (LNG) in Central India. By constantly innovating and improving the technology that drives the LNG industry, we have found newer ways to make the fuel readily available wherever it is needed.


LNG is a clear, colorless, and non-toxic liquid, formed when natural gas is cooled to -162ºC (-260ºF). The cooling process contracts the volume of the gas 600 times, making it easier and safer to store and ship. Moreover, LNG doesn’t ignite in its liquid state. 

At regasification plants, LNG is turned back into a gas, which is then piped to homes, businesses, and industries for heat or to generate electricity. LNG has proved to be a cost-competitive and cleaner transport fuel, especially for shipping and heavy-duty road transport.


Natural gas already is a common fuel for road transport in the form of compressed natural gas (CNG).  However, the arrival of LNG as a transport fuel offers advantages, especially for the higher horsepower vehicles.

A key advantage of LNG over CNG as a transport fuel is its energy density, which enables storage of more natural gas in the fuel tanks, thus providing a much longer range. LNG fueled trucks have a range of about 1,500 kilometers without the need for refueling. This bigger operating radius makes LNG a competitive alternative for use in regional distribution as well as long haul transport, while CNG is mostly used for limited city distribution and garbage collection.
