Here is the EIA’s “Today in Energy”:
“Over the next two years, EIA’s Short-Term Energy Outlook (STEO) projects growth in U.S. consumption of ethane in the petrochemical industry will exceed increases in consumption of all other petroleum and liquid products—such as motor gasoline, distillate, and jet fuel—combined. EIA also projects that ethane exports will continue increasing, as ethane is exported both by pipeline to Canada and by tankers to more distant destinations.
Ethane is separated from raw natural gas at natural gas processing plants along with other hydrocarbon gas liquids (HGL) such as propane, normal butane, isobutane, and natural gasoline. Ethane is mainly used as a petrochemical feedstock for the production of ethylene, which is a building block for plastics, resins, and other industrial products.”
