Methane
A hydrocarbon that is a greenhouse gas with a global warming potential most recently estimated at 21. Methane is produced through anaerobic (without oxygen) decomposition of waste in landfills, animal digestion, decomposition of animal wastes, production and distribution of natural gas and petroleum, coal production, and incomplete fossil fuel combustion. The atmospheric concentration of methane as been shown to be increasing at a rate of about 0.6 percent per year and the concentration of about 1.7 per million by volume (ppmv) is more than twice its pre-industrial value. However, the rate of increase of methane in the atmosphere may be stabilizing. (source: EPA) Background from Wikipedia The simplest hydrocarbon, methane, is a gas (at standard temperature and pressure, STP) with a chemical formula of CH4. Pure methane is odorless, but when used commercially is usually mixed with small quantities of odorants, strongly-smelling sulfur compounds such as ethanethiol (also called ethyl mercaptan), to enable the detection of leaks. The principal component of natural gas, methane is a significant and plentiful fuel. Burning one molecule of methane in the presence of oxygen releases one molecule of CO2 (carbon dioxide) and two molecules of H2O (water): CH4 + 2O2 ? CO2 + 2H2OMethane's relative abundance and clean burning process makes it a very attractive fuel. However, because it is a gas and not a liquid or solid, methane is difficult to transport from the areas that produce it to the areas that consume it. Converting methane to forms that are more easily transported, such as LNG (Liquified Natural Gas) and methanol, is an active area of research. Methane is a greenhouse gas with a global warming potential over 100 years of 23.[1] When averaged over 100 years each kg of CH4 warms the earth 23 times as much as the same mass of CO2. The Earth's crust contains huge amounts of methane. Large amounts of methane are emitted to the atmosphere through mud volcanoes which are connected with deep geological faults or as the main constituent of biogas formed naturally by anaerobic digestion.
