Process for in situ coal gasification - Ramcor, Inc.

15-04-1980· A process for in situ gasification of coal to produce a combustible methane rich product gas which comprises injecting a lower aliphatic alcohol into an underground coal seam, raising the temperature of the seam sufficiently to cause vaporization and dissociation of the alcohol into carbon monoxide and nascent hydrogen and initiate a hydrogasification reaction, within the coal seam, and ...

Coal Seam - an overview | ScienceDirect Topics

In general, the higher the rank of coal and the greater the depth of coal seam, the higher is the gas content of coal. Gas content of coal seams vary from a few ft 3 /t to 800 ft 3 /ton for depth up to 3000 ft. Coal seams are the source as well as the reservoir for all gases. Methane is the major component of gas in coal, comprising 80%–95% ...

Water and coal seam gas - about coal seam gas

Coal seam gas (CSG) is a form of natural gas that occurs in coal seams laid down mainly during the Permian period, between 299 million and 251 million years ago. In NSW the coal seams targeted for gas production are generally found between 200 metres an d 1000 metres below the ground.

Coal Seam Gas | IDE Technologies

The Coal Seam Gas (CSG) process is a natural gas extraction process from coal seams buried in the ground. In order to release the gas, the coal seams are de-pressurized by releasing large volumes of water. The water that is a by-product of the CSG production process often has difficult water chemistry, such as high silica and alkalinity.

Natural-gas processing - Wikipedia

Natural-gas processing is a range of industrial processes designed to purify raw natural gas by removing impurities, contaminants and higher molecular mass hydrocarbons to produce what is known as pipeline quality dry natural gas.. Natural-gas processing begins at the well head. The composition of the raw natural gas extracted from producing wells depends on the type, depth, and location of ...

What is coal seam gas? – GISERA

Coal seam gas (CSG), also known as coal bed methane, is a form of natural gas typically extracted from coal seams at depths of 300-1,000 metres. CSG is a mixture of a number of gases, but is mostly made up of methane (generally 95-97 per cent pure methane).

Coal seam - Energy Education

Coal seams can pose a fire hazard, and as a result sometimes begin to smoulder.Generally, these fires are ignited by above ground fires but can continue to smoulder underground for many years. Sometimes these fires can burn for decades or centuries until the fuel below the surface is used up or the fire is extinguished. One of the most widely known coal seam fires is the Centralia mine fire ...
