Natural gas is a type of fuel that is extracted from the earth. It is composed of methane and other gasses. One way to remove HS from natural gas is to use an Activated Carbon Filter. This filter removes the HS from the gas before it is used. Activated carbon is a type of filter that can adsorb chemicals and toxins.
Another way to h2s removal from natural gas is to use a Gas Absorber. This device traps the HS in the gas and then removes it. Gas absorbers are often used in factories that produce chemicals and fuels. Another way to remove HS from natural gas is to use a Liquid Adsorber. This device captures the HS in a liquid that can be easily removed from the gas. A liquid adsorber can be used in factories that produce chemicals and fuels.

Fuel tanks for CNG vehicles must be made with a steel reinforced plastic frame. The tank must also have an internal insulation system installed as well as fittings for the fuel lines and gauges to maintain pressure and temperature.
The tank itself is made out of fiberglass or high density plastic. It one has steel reinforcements inside it, then it is called a composite tank. Composite tanks are lighter but more expensive than standard tanks.
