The main component of coal mine gas is methane, which is the second largest greenhouse gas in the world. Controlling coal mine gas can not only reduce gas hazards, but also reduce greenhouse gas emissions. The utilization of high concentration gas is very mature, such as high concentration internal combustion power generation, pipeline civilian gas, LNG, CNG, etc; Low concentration gas waste heat can be used for power generation, heating, and other purposes. This article will introduce the main applications of coal mine gas treated with oxidation technology.

Coal mine gas power generation

Coal mines produce a large amount of gas, and if not discharged properly, it not only pollutes the environment, but may also cause huge casualties such as gas explosions. Of course, we can collect and purify coal mine gas for power generation. The advantages of coal mine gas power generation are obvious, as it can utilize close range power supply in coal mine areas to solve problems such as distant power grids and high transmission line losses.

Coal mine gas heating

Due to the high heat content of coal mine gas, it can be used as fuel for heating. In some high-altitude areas, coal mine gas can be directly used for heating and domestic heating, which can solve the heating problem of local residents, reduce operating costs, and minimize gas emissions and safety accidents.

Industrial application of coal mine gas

Coal mine gas contains organic compounds such as alkanes and alkenes, which can be used to produce chemical raw materials. Methane and ethane in coal mine gas can be used not only to produce organic chemicals such as dimethyl ether, propylene, and propane, but also to produce synthetic lubricants, solvents, fuels, etc., with high economic value and application prospects.

Coal mine gas has many uses besides being used for power generation and heating. For example, its greenhouse gas properties can be utilized to promote crop growth in agricultural applications; Can provide backup power for the local power grid; Can produce products such as gas lamps. In short, through the collection and utilization of coal mine gas, in addition to promoting the green and sustainable development of the coal mining industry, it can also generate higher economic benefits.
