Gas is all that exists in the nature of natural gas, including atmosphere, hydrosphere, and lithosphere in various natural process of gas formation, as the increasing of environmental pollution, clean energy by many countries and regions, also is one kind of clean energy, natural gas has attracted the attention of people, and gradually come into the mind of the public, it is colorless, tasteless, no toxicity, Good performance, in many production have been used, widely used by people. We should also know its performance when we use it, so that we can use it well. So what are the performance of natural gas?

Gas Cylinder

1. LNG is mainly composed of methane, chemically named CH4, and a small amount of ethane C2H6, propane C3H8, nitrogen N2 and other components.

2. the critical temperature is -82.3℃, the critical pressure is 45.8kg/cm3, the boiling point is -162.5℃, the melting point is -182℃, the ignition point is 650℃.

3. Liquid density is 0.430t /m3, gaseous density is 0.688kg/Nm3, gaseous calorific value is 9100Kcal/m3, liquid calorific value is 12000Kcal/kg.

4. explosion range: the upper limit is 15%, the lower limit is 5%.

5. White index (W) 44.94MJ/Nm3, combustion potential (CP) 45.18, octane number ASTM:130.

6. colorless, tasteless, non-toxic and non-corrosive, the volume is about 1/625 of the volume of the same amount of gaseous natural gas.

Natural gas can be divided into free state, dissolved state, adsorbed state and solid hydrate state according to the phase states existing underground. Only the free natural gas can be exploited and utilized by the accumulation of natural gas. Because natural gas is a kind of clean energy, it has made its own contribution to the environmental protection of the earth. In this resource-constrained era, the use of natural gas is beginning to grow, and it will be relied upon even more in the future. Natural gas is one of the safer gas, it does not contain carbon monoxide, but also lighter than air. Once leaked, it will immediately diffuse upward, not easy to accumulate and form explosive gas, and the safety is relatively higher than other combustion bodies.
