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 ...

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.
Price per million BTU of oil and natural gas in the US, 1998-2015. Natural gas prices, as with other commodity prices, are mainly driven by supply and demand fundamentals. However, natural gas prices may also be linked to the price of crude oil and petroleum products, especially in continental Europe.
In 2018, American Ethane began constructing the largest United States export terminal for ethane on the Gulf Coast. [5] [7] [9] The Energy & Minerals Group (EMG), established in Houston by John T. Raymond in 2006, [13] [14] is co-developing the 10 million ton per year ethane port. [9] Construction is to be completed by 2020. [7]
where OP is the annual average Brent crude price for the previous FY, with a cap of $60 per barrel and a floor of $25 per barrel. [10] As the annual Brent price has always been above $60 from 2007 to 2014, the revised gas price at $5.61 during the year 2014 is in excess of the applicable maximum price by nearly 20%.
Both steam cracking and production from natural gas via ethane are estimated to emit 1.8 to 2kg of CO2 per kg ethylene produced, [54] totalling over 260 million tonnes a year. [55] This is more than all other manufactured chemicals except cement and ammonia. [ 56 ]
