A planned ethane cracking plant proposed for development in Beaver County, Pennsylvania, US is expected to use a gas-fired cogeneration plant to supply on-site power and process heat. Shell Chemicals’ plant is anticipated to require at least 100 MW of power, local media report.

Last November Shell Chemical exercised its option to purchase the site of a former Horsehead zinc smelter (pictured) in Monaca, Pennsylvania, for the proposed $4 billion ethane cracker.

Although a final investment decision has not been confirmed, media report the plant is expected to be completed in 2019 and would upgrade locally produced ethane from Marcellus Shale gas production.
