The first German gas plant was built in Hannover in 1825 and by 1870 there were 340 gas plants in Germany making town gas from coal, wood, peat and other materials. Working conditions in the Gas Light and Coke Company 's Horseferry Road Works, London, in the 1830s were described by a French visitor, Flora Tristan, in her Promenades Dans Londres :
Coalbed methane (CBM or coal-bed methane), [1] coalbed gas, or coal seam gas (CSG [1]) is a form of natural gas extracted from coal beds. [2] In recent decades it has become an important source of energy in United States, Canada, Australia, and other countries. The term refers to methane absorbed into the solid matrix of the coal.
Most gas in coal is stored on the internal surfaces of organic matter. Because of its large internal surface area, coal stores 6 to 7 times more gas than the equivalent rock volume of a conventional gas reservoir. Gas content generally increases with coal rank, with depth of burial of the coal bed, and with reservoir pressure.
Underground coal gasification (UCG) is an industrial process which converts coal into product gas. UCG is an in-situ gasification process, carried out in non-mined coal seams using injection of oxidants and steam. The product gas is brought to the surface through production wells drilled from the surface. [1]
Tried as a pilot for one semester, the oil and gas pathway drew 20 students. Now in its first full year, there are about 60 students signed up. Justin Young and Ofrael Galindo are both oil and gas ...
A coking factory or a coking plant is where coke and manufactured gas are synthesized from coal using a dry distillation process. The volatile components of the pyrolyzed coal, released by heating to a temperature of between 900°C and 1,400 °C, are generally drawn off and recovered. There are also coking plants where the released components ...
In the United Kingdom the discovery of large reserves of natural gas, or sea gas as it was known colloquially, in the Southern North Sea off the coasts of Norfolk and Yorkshire in 1965 [8] [9] led to the expensive conversion or replacement of most of Britain's gas cookers and gas heaters, from the late 1960s onwards, the process being completed ...
This program is the first aimed at commercial recovery of gas rather than mine degasification. It is also the first attempt to produce from more than one coal seam in the same wellbore. [citation needed] The coalbed methane wells were drilled on the lawn of the Pleasant Grove court house. The gas was of sufficient quality to be ducted into the ...
