Dear friends, please provide a comparison of the component specifications for coal-based natural gas and petroleum-based natural gas. Thank you very much!
Based on their formation, natural gas can be classified into four types: field gas, coalbed methane, biogas, and hydrate gas. Oilfield gas is natural gas composed of petroleum hydrocarbons; coalbed methane is methane gas produced from organic matter during the coal formation process; biogas is methane gas generated when organic matter is decomposed by anaerobic microorganisms at temperatures below 70°C; and hydrate gas is a gas formed when gas molecules such as methane penetrate into the crystal gaps of water molecules under low temperature and high pressure. Based on their production method, they can be divided into liquefied natural gas and compressed natural gas. Liquefied natural gas is formed when natural gas is cooled to about -162°C at atmospheric pressure, causing it to change from a gaseous state to a liquid state; this is what is known as liquefied natural gas. Liquefied natural gas is colorless, odorless, non-toxic, and non-corrosive. Its volume is about 1/600 of that of the same amount of gaseous natural gas, and its weight is only around 45% of that of water in the same volume. Compressed natural gas is natural gas that has been pressurized and stored in a container in gaseous form. It has the same composition as pipeline natural gas and can be used as a vehicle fuel. Composition table of coal-based synthetic natural gas: Components – CO, CO2, N2+Ar, H2, CH4; Total content in %: 0.05, 0.77, 1.0, 2.48, 95.7, 100.00. Oil and natural gas consist mainly of methane; their composition varies depending on the source site, and they can be classified as dry gas or wet gas, and can be purified. **There are standards for natural gas to enter the grid. However, there are no standards for liquefied natural gas yet.
The composition table of coal-based synthetic natural gas on the second floor is the one obtained after completing the entire methanation process, and it is highly accurate.
Excuse me, friend on the second floor, **what are the standards for natural gas to enter the network
