CNG Processing Equipment Compressed Natural Gas
CNG processing equipment, Compressed Natural Gas (CNG), is pressurized by Natural Gas and stored in a Gas tank in the gaseous state.In addition to natural gas in fields and natural gas fields, compressed natural gas can also be used to make bio-biogas (mainly methane).Compressed Natural Gas is the same composition as pipeline Gas, uefied Natural Gas, or liquefied Natural Gas, and the CNG fuel vehicle is called the NaturalGasVehicle.Liquefied Petroleum Gas (LPG) is often easily confused with LNG, but there is a clear difference.The main components of LPG are propane (over 95%), and a small amount of butane, which is stored in liquid storage tanks under appropriate pressure and is used as a civilian fuel and vehicle fuel.
Natural gas has a lot of components, but each component has no chemical effect on each other, and the nature and content of each component determine the nature of natural gas.Natural gas is also called methane because it contains more than 90 percent of the methane.
Natural gas is colorless and tasteless, but before it reaches the end user, it is also used to add the smell of gas to the gas to help leak detection.Natural gas is not as toxic as carbon monoxide, which is essentially harmless to humans.If gas is in a state of high concentration, can lead to carbon monoxide poisoning, and not enough oxygen to sustain life in the air, can cause or could be deadly, natural gas, after all, can not be used in humans to breathe.
Methane is a colorless, odorless gas, burning shimmering blue flame, lighter than air, can be turned into liquid under high pressure in low temperature. The critical temperature of 82.11 ℃, the critical pressure is 4.64 MPa.After liquefaction, the volume will be reduced to 1/600, and the methane from the lNm will be 9.52 Nm.
The explosive limit of methane in air is: 5% lower limit;The upper limit of 15% natural gas is methane, ethane, propane, isobutane, etc., and a small amount of hydrocarbons, nitrogen, helium, sulfur dioxide, etc.
Compressed natural gas is one of the most ideal alternative energy sources, and its application technology has been maturing for decades.It has the characteristics of low cost, high efficiency, no pollution, safe and convenient use, etc., and it is showing strong development potential.Natural gas refueling stations are divided into three basic types: quick filling, ordinary (slow) filling and mixed type.
Compressed natural gas is also used in the urban gas industry, especially for residents living with fuel.With the improvement of people's living standard and the enhancement of environmental awareness, the demand for natural gas in most cities has increased significantly.Natural gas (pipeline gas) is also more economical than industrial fuel for civilian fuel.
