Can Any One Tell Me The Difference Between Petroleum, Coal And Bacterial Gas?
The petroleum gas, the coal gas and the bacterial gas are the three origins of the natural gas. Natural gas consists of hydrocarbons not condensable at 20°C (68°F) and atmospheric pressure; this effectively means the first four members of the paraffin series, methane through n-butane. atural gases consisting largely or wholly of methane may have any one of three distinct origins. a. Petroleum gas; may be formed as a by product of the generation of petroleum. In this case the gas either accompanies oil in its subsurface reservoir, or it is contained in a separate reservoir among other reservoirs containing oil. Such gas is called associated gas. Petroleum gas may alternatively be formed by the thermo catalytic modification of petroleum under the temperature prevailing in deep reservoirs. This gas no longer accompanies oil and is called non associated gas. b. Coal gas; is formed by the modification of the coal, thermo catalytically or otherwise.
