Chinese purchases of U.S. ethane, a key petrochemical feedstock, face fresh uncertainty after the Commerce Department told ...

Natural gas liquids (or NGLs) are a group of hydrocarbons—ethane, propane, butanes, and pentanes—that are often found alongside dry natural gas—methane ... 7% normal butane, ~9% isobutane ...

It's got no color or smell to it, and is 70-90 percent methane, with ethane, propane, butane, and pentane making up the rest. Once extracted, the gas goes through a processing station where it is ...

But the rest of the liquids, with smaller carbon chains — like ethane, propane and butane — remain in the natural gas stream ... for a great deal more money than do comparable volumes of methane. This ...

which include components like butane, methane, and ethane, as well as some other hydrocarbons. While all of that may have ...

They can clearly indicate the way in which hydrocarbons like methane, ethane, propane, butane and pentane are formed. When hydrocarbons are combusted, water and carbon dioxide are produced and ...

Propane and butane are gaseous under normal standard ... Recent studies have shown that propane is degraded in situ along with methane and ethane in oxic, hydrocarbon-contaminated marine sediments ...

Boiling Point: Propane has a lower boiling point than butane (-44°F vs. 31°F), which means propane remains gaseous and functional in colder temperatures, while butane may struggle in freezing ...
