What compressed natural gas?
CNG, also known as compressed natural gas, is an eco-friendly alternative to gasoline. Made by compressing natural gas (methane) down to less than 1% of its volume, CNG fuel is safer than gasoline and diesel because it is non-toxic and does not contaminate ground water.
What are the properties of compressed natural gas?
The following are the properties of Natural Gas :
- The state of matter of this gas is gaseous.
- It doesn’t have any color and is a tasteless gas.
- It is free of any kind of toxic, there is no smoke on burning and it has high calorific value.
- The gas is odorless.
- It is a combustible gas and a fossil fuel.
How flammable is compressed natural gas?
The flammability range of natural gas is very narrow, that is, natural gas will not burn in concentrations of air below about 5 percent and above about 15 percent. The high ignition temperature and limited flammability range make accidental ignition or combustion of CNG unlikely.
What does compressed natural gas smell like?
Natural gas is an efficient, safe, colorless and odorless gas. For easy detection, we add a harmless chemical called mercaptan to give gas a distinctive odor. Most people describe the smell as rotten eggs or hydrogen sulfide like odor. It smells bad for a good reason – in case of a gas leak!
What is a fact about natural gas?
Natural gas is the earth’s cleanest burning hydrocarbon. Its combustion does not produce ash residues, sulphur oxides, and only negligible nitrogen. Natural gas forms organically over millions of years from decomposing plant and animal matter that is buried in sedimentary rock layers.
Is compressed natural gas cheaper than gasoline?
According to the Environmental Protection Agency, NGVs pave the potential to emit 25 percent less greenhouse gases than diesel-powered vehicles. Best of all, natural gas is cheaper — $1.50 to $2 less per gasoline gallon equivalent, according to NGVAmerica.
What is natural gas used for?
The commercial sector uses natural gas to heat buildings and water, to operate refrigeration and cooling equipment, to cook, to dry clothes, and to provide outdoor lighting. Some consumers in the commercial sector also use natural gas as a fuel in combined heat and power systems.
Is natural gas combustible or flammable?
Natural gas has a flammability range of approximately 5 to 15 percent. That means that any mixture containing less than 5 percent or greater than 15 percent natural gas to air would not support combustion. Natural gas, when mixed with air and exposed to an ignition source, is combustible.
