The perspective of the birth canal: when coal bed methane can make up for energy shortages
2018-06-21 23:00:16
Recently, relevant departments in Shaanxi Province learned that the first coal-bed methane power generation project in the province has been completed and put into operation, and a coal safety technology research institution will be set up to focus on the management and utilization of coal mine gas disasters. At the same time, the Japanese Energy Center is eager to try and develop coalbed methane in the Binchang coal mine in Shaanxi. Coal reserves ranks fourth in the country in Shaanxi Province, and it has begun to focus on the new type of clean energy, coalbed methane.
Gas (coalbed methane) is the number one killer of coal mine safety in China. But it is also a good source of energy and chemicals. Relevant statistics show that China’s coalbed methane resources amount to 31 trillion cubic meters, equivalent to 45 billion tons of standard coal or 31 billion tons of oil, of which Shanxi, Shaanxi, and Inner Mongolia account for more than 50% of the total. The main components of coal bed methane are the same as natural gas, and two gases can be mixed. After being processed, the CBM in the west of China can directly enter the West-East Gas Pipeline, or supply nearby urban residents and industrial users. It can be said that CBM is the most realistic and reliable alternative energy source for natural gas in China. Exploiting and utilizing this high-quality and clean new energy can optimize China's energy structure to a certain extent, improve coal mine safety production conditions, and protect the atmosphere.
According to the person in charge of the Planning and Development Division of Shaanxi Coal Industry Bureau, Shaanxi Province has at least 100 billion cubic meters of CBM reserves. Considering the safety production of coal mines, coal mine methane has been used as a dangerous gas for coal mines to empty along with coal mining. This wastes resources and pollutes the environment. Every year, coal mines in China discharge more than 19 billion cubic meters of coalbed methane.
With the advancement of western development, especially in the current situation of energy shortage, the development of coalbed methane as an energy source has attracted great attention in Shaanxi Province. According to the Shaanxi Provincial Bureau of Work Safety, the Measures for the Management of High Gas and Coal and Gas Outburst Mines in Shaanxi Province will be issued soon. In May of this year, Shaanxi Tongchuan Mining Bureau and Shengli Oilfield invested 14 million yuan and built a coal-bed methane power generation project with a scale of 8×500 kW at the Xiashijie Coal Mine. The coal bed methane extracted during coal mining was used to generate electricity, and the coal seam of Shaanxi Province was first opened. Gas power generation. It is reported that the Japan Energy Center is negotiating with the Shaanxi Provincial Department of Technology to provide technology for the other party to install a CBM plant at the newly-built Binchang Coal Mine. Before the coal mining, coalbed methane is first extracted for use, and fundamentally prevented. Coal mine gas accident.
Ren Kelong, deputy chief engineer of Shaanxi Coal Industry Group, told the reporter that the resources of coalbed methane are directly related to coal mining. If gas is not produced before coal mining, coal bed methane is discharged into the atmosphere as coal is extracted. Shaanxi Coal Industry Group invests 160 million yuan each year in gas comprehensive management, establishes a special fund for gas treatment in high gas and gas outburst mines, updates gas monitoring systems and extraction equipment, and has three high gas resources in Xiashijie Coal Mine. The mine developed pilot pre-drainage and gas utilization pilots, and strived to turn the high-gas mine of the state-owned coal mining enterprise into a low-gas mine within five years, and the high-gas area in the low-gas mine turned into a low-gas area. Hancheng Coal Mine and Tongchuan Mine, both subsidiaries of the Group, are preparing to directly extract coal-bed methane from the surface of the ground and build a number of CBM power stations.
Not long ago, the 11th expert group of national coal mine safety expert consultations visited the Hancheng Mining Bureau of Shaanxi Province and the Tongchuan Mining Bureau on the spot and conducted consultations to study the treatment of coalbed methane. According to the opinions of the expert group, Shaanxi Province is actively preparing for the establishment of a coal safety technology research institute to specifically study the management and utilization of coal mine gas disasters.
The reporter learned from the interview that the main problem currently plaguing the comprehensive utilization of CBM in Shaanxi is the lack of technology and funds. According to relevant experts, the content of coalbed methane extracted during coal mining is low, not exceeding 27%, and comprehensive utilization is difficult. Ground extraction and purification technologies are still immature in China. Shaanxi Qinlian Coal Bed Methane Science and Technology Development Co., Ltd., which is dedicated to the development of coalbed methane, is preparing to invest several hundred million yuan to develop coalbed methane in places such as Hancheng, Shaanxi, and plans to build projects such as power generation, chemical and gas stations, and is currently attracting investment. When it comes to this project, the company's CEOs poured hard water to reporters: difficulties in funding, and difficulties.
When will CBM make up for energy shortages? We will wait and see.
