Coal bed methane air compressor adopts water lubrication air compressor scheme is better

The water-lubricated air compressor head produced by Shanghai Granklin Group is suitable for coalbed methane mining. The head of water lubricated air compressor has the characteristics of low temperature and high gas cleanliness, and there are many cases in process gas compression.

Coalbed methane is a high-quality gas of modern clean energy. Coal mining all over the country is inseparable from water-lubricated air compressors to extract coalbed methane.

"Coalbed methane" is the "miner killer" in the roadway, and an unexpected spark may lead to a mine tragedy. With the gradual deepening of human understanding of it, it has been mined from underground on a large scale, which not only effectively guarantees the life safety of miners and other underground workers, but also enters cities, factories and villages through pipelines, becoming a common one in people's production and life. One of the clean energy.

Over the past 40 years of reform and opening up, China has made world-renowned achievements in the field of coalbed methane exploration and development. Guided by a series of technological breakthroughs, the coalbed methane industry has developed rapidly from scratch, from small to large, and has greatly improved the safety production environment of coal mines. It has greatly improved the efficiency of coal mining, and has taken the lead in developing into one of the large-scale commercial exploitation and use of unconventional natural gas, and has become the surging power to drive "China" China.

high quality, clean and efficient, rich and widely distributed reserves

coalbed methane, also known as "coal mine gas", is a hydrocarbon gas that exists in coal seams and coal-bearing strata. The main component is methane, which is an associated mineral resource of coal. When its concentration in the air reaches 5% to 16%, it will explode in case of open fire, which was once one of the main threats to coal mine safety production, so it has been notorious as a "miner killer. On the other hand, coal-bed methane is a good industrial, chemical, power generation and residential fuel. One cubic meter of coalbed methane is equivalent to about 9.5 degrees of electricity, 1.13 kilograms of gasoline and 1.21 kilograms of standard coal. The calorific value of coalbed methane is 2 to 5 times that of general-purpose coal, and it hardly produces any exhaust gas after combustion. It is a well-deserved "high-quality" clean energy.

Before coal mining, mining the associated coalbed methane can not only reduce the coal mine gas explosion rate by 70% ~ 85%, fundamentally improve the coal mine safety environment, but also obtain an important and rich clean energy, which can produce great economic value.

At present, there are two main ways to develop coalbed methane resources: one is ground drilling and mining; the other is underground extraction. Underground extraction means that coal is mined first and then gas is extracted, or coal is mined while gas is extracted. Most of the extracted coalbed methane is still discharged into the atmosphere and cannot be used rationally. The ground drilling and mining is the first gas mining and then coal mining, which creates the premise for the use of coalbed methane and is also conducive to improving the safety production conditions of coal mines. Obviously, ground drilling is a more advanced and excellent way to promote the efficient use of energy resources.

Although coalbed methane is accompanied by coal, it also has its own unique nature. It cannot be developed completely in accordance with the method of oil and gas exploration and development, but needs to adopt a method that conforms to its characteristics.

at present, the drainage mechanism of coalbed methane is: drainage of coal seam confined water, reducing the pressure of coal reservoir, promoting the desorption of adsorbed methane into a large number of free methane, and transported to the wellhead under the action of formation pressure and wellbore pressure difference.

The development and utilization of coalbed methane is a huge project, involving the exploration and drilling stages of coalbed methane, the collection, pressurization and transportation of coalbed methane, as well as the process of making CNG and LNG products after coalbed methane purification treatment. in these links, it is inseparable from the cooperative operation of all kinds of machinery and equipment. Compressor is the essential core device of coalbed methane collection, pressurization and transportation equipment. With policy support and guidance and the vigorous development of coalbed methane, the future demand for coalbed methane compressors will be more and more, and will give birth to the compressor industry new generation legion.
