CNG Plant

Since 1960s, CNG is recognized as a vehicle fuel alternative to oil-based gasoline and diesel fuel that reduces pollution of the air we breathe and also reduces. It is a natural gas compressed to a volume and density that is practical as a portable fuel supply. Compressed natural gas (CNG) as a vehicle fuel is the same clean and safe, natural gas that is used to cook food and heat homes.

Natural gas contains less carbon than any other fossil fuel and, therefore produces less carbon Dioxide (CO2) when compared to any conventional vehicles. Its usage also results in significantly less carbon monoxide (CO), as well as less combustive organic compounds than their gasoline counterparts.

Compressed Natural Gas (CNG) is made by compressing purified natural gas, and is typically stored and distributed in hard containers. Mostly, a CNG station is created by connecting a fuel compressor to the nearest underground natural gas pipeline distribution system.

The CNG Plant
CNG is basically produced by pressing natural gas at 3,000 psi pressure. Compressed Natural Gas (CNG) is usually produced on the fueling station site with a compressor based system. Natural gas is transported through pipelines to refueling stations and there compressed at a pressure of 3,000 psi with the help of specially installed compressors that enables it to be loaded as gas cylinders for vehicles.

The process consists of drawing the natural gas from underground pipelines by the compressor. The composition of pipeline natural gas vary considerably depending on the time of year, pipeline demand, and pipeline system. It may contain impurities, like, oil, particulates, hydrogen sulfide, oxygen or water. Hence the modern day, quality CNG Plant system consists of facilities to address problems caused by them.

Using LNG as the feedstock to make CNG eliminates or mitigates each of the above stated concerns as contains no water or any such impurity. This eliminates the concerns for corrosion, plugging of fuel lines, and the formation of hydrates. LNG is not even subject to compositional changes driven by the time of year, pipeline demand, or pipeline system and can be delivered as pure methane, which is actually the most desirable component of natural gas.

Significant Innovation
A new kind of CNG technology is being developed which promises lower costs and shorter scheduling time than either Liquefied Natural Gas technology or a pipeline transport. This technology may provide a unique solution to the development of distressed or stranded gas reserves and provides an alternative to associated gas re-injection.
