Ethane (US: / ˈ ɛ θ eɪ n / ETH-ayn, UK: / ˈ iː θ eɪ n / EE-thayn) is a naturally occurring organic chemical compound with chemical formula C 2 H 6. At standard temperature and pressure, ethane is a colorless, odorless gas. Like many hydrocarbons, ethane is isolated on an industrial scale from natural gas and as a petrochemical by ...
Phase behavior Triple point: 91 K (−182 °C), 1.1 Pa Critical point: 305.3 K (32.2 °C), 4.9 MPa Std enthalpy change of fusion, Δ fus H o: 9.76 kJ/mol at −182 °C
The heating value depends on the source of gas that is used and the process that is used to liquefy the gas. The range of heating value can span ±10 to 15 percent. A typical value of the higher heating value of LNG is approximately 50 MJ/kg or 21,500 BTU/lb. [2] A typical value of the lower heating value of LNG is 45 MJ/kg or 19,350 BTU/lb.
Anthropogenic sources emit about 142 teragrams (1.42 × 10 11 kg, or 142 billion kg) of carbon per year in the form of VOCs. [31] The major source of man-made VOCs are: [32] Fossil fuel use and production, e.g. incompletely combusted fossil fuels or unintended evaporation of fuels. The most prevalent VOC is ethane, a relatively inert compound.
In contrast, wet natural gas also contains significant portions of other liquids such as ethane, propane or butane (also known as Natural Gas Liquids). Wet natural gas is used for petrochemicals as well as gasoline (petrol). In 2023, the United States has led the world in both natural gas production and natural gas exports.
The chemical compound 1,2-dichloroethane, commonly known as ethylene dichloride (EDC), is a chlorinated hydrocarbon.It is a colourless liquid with a chloroform-like odour. ...
Specific energy is energy per unit mass, which is used to describe the chemical energy content of a fuel, expressed in SI units as joule per kilogram (J/kg) or equivalent units. [1] Energy density is the amount of chemical energy per unit volume of the fuel, expressed in SI units as joule per litre (J/L) or equivalent units. [2]
