Low ethane prices and higher costs for storing and transporting ethane have resulted in ethane rejection. This means that producers leave ethane in the natural gas stream. Extracting ethane isn’t always economical when prices are low. The costs of storing and transporting ethane are higher than the related costs for hydrocarbon gas liquids products. Read What is ethane rejection and why is it important for energy MLPs? to learn more about ethane rejection.

One of the developments is higher ethane use from petrochemical companies. Lower ethane prices have resulted in petrochemical companies’ using ethane more as a feedstock in place of naphtha.
The EIA (U.S. Energy Information Administration) expects the increased use of ethane by petrochemical companies to continue. Ethane is used to produce ethylene. Ethylene is used to produce plastics. This trend should increase ethane demand.
Ethane-related infrastructure, including plants to convert ethane to ethylene, has been developing in the United States. This development supports rising demand for petrochemical companies. This is positive for ethane demand. Eventually, it will be positive for prices. Some companies are investing in export terminals for ethane. There are attractive export markets for ethane in Canada, Asia, and Europe.
