Shanxi Ruiyang 50,000 tons of oxygen-containing coal-bed methane liquefaction project has a total investment of 210 million yuan, a total area of ​​about 60 acres and a total construction area of ​​about 100,000 square meters. The construction period is 7 months, and the production capacity of the first phase is 3,500 cubic meters of CNG per year. The second phase of the project was implemented simultaneously with the construction of Sijiazhuang Mine, and finally reached the design capacity of 50,000 tons of LNG (equivalent to 90 million cubic meters of CNG) per year. The successful implementation of the project will contribute to the greening of Shanxi, the gasification of Shanxi, the purification of Shanxi, and the health of Shanxi, as well as the construction of a new Xiyang with blue sky and clear water. The project uses pressure swing adsorption enrichment technology to purify and liquefy liquid methane with a concentration of more than 99% from the gas. The completion of the project creates a precedent for the development and utilization of low-concentration coal mine gas in the country and the world. It is extremely important for the development and utilization of coalbed methane in my country in the future. Demonstration.
