At standard temperature and pressure, ethane is a colorless, odorless gas. Ethane is isolated on an industrial scale from natural gas, and as a byproduct of petroleum refining. Its chief use is as petrochemical feedstock for ethylene production.
Most of the emissions from ethane cracker plants come from the process of âsteamâ cracking ethane, a hydrocarbon found in âwetâ natural gas like the Marcellus shale, says Goetz Veser, a professor of chemical engineering at Pitt.lso by this author: Monaca, Pa. could be the site of an ethane cracker like this one built by Shell in Singapore, which releases around 2,000 tons of NOx a year.
