What are the advantages of natural gas over gas?

Comparative advantages mainly include the following aspects:

1. Natural gas is mined underground and then transported to users. This gas is made by dry distillation of coal. The process of gas production (coal mining, transportation, storage, gas production and coal coke treatment) pollutes the environment much more seriously than the exploitation and transportation of natural gas. ?

2. Natural gas itself is non-toxic, and there is a lot of CO in the gas, which will do great harm to people once it leaks; ?

3. When the compound is burned, the calorific value with high carbon content is high. You know, both natural gas and gas have higher calorific value than natural gas. Compared with 1kg coal and 1 m3 natural gas, the calorific value of natural gas is 8300 to 9000 kcal, while the calorific value of coal is less than half of that of natural gas. The thermal efficiency of natural gas can reach more than 75%, while that of coal is only 40-60%.

One of the main reasons for using natural gas is that it has irreplaceable advantages compared with other energy sources.

1, high quality: low temperature treatment, almost no sulfur and other impurities.

The main component of natural gas is methane (CH4), which is simple in composition and high in purity. It is very suitable for advanced fuels and chemical raw materials with high quality requirements.

2, environmental protection: clean combustion, emissions are mainly carbon dioxide and water.

Natural gas is considered as the cleanest fossil energy on earth, and the main emissions after combustion are carbon dioxide (CO2) and water (H2O). As city gas, natural gas can be widely used in changing industrial and commercial users' oil into gas, replacing oil-fired vehicles to develop natural gas vehicles, using gas-fired air conditioners in newly-built large hotels, using fuel for large industrial users, and switching oil-fired boilers to gas-fired boilers.

3, safety: lighter than air, easy to spread, not easy to gather.

Natural gas is lighter than air, so it will not accumulate after leakage and will not volatilize quickly. In addition, the odorizing agent is added to the gas supply device in the process of natural gas transportation, which is convenient for timely discovery and treatment of natural gas leakage.
