Corunna Site
Corunna, Ontario, Canada

Corunna Site 
Located in Sarnia-Lambton's Chemical Valley, about
180 miles (288 kilometers) southwest of Toronto, NOVA Chemicals' Corunna site is a petrochemical complex that
produces 1.9 billion pounds of ethylene and up to 1.1 
billion pounds of co-products annually.
The Corunna facility started up in late 1977 and was purchased by NOVA Chemicals in 1988. It was the first fully integrated refinery and petrochemical complex in North America. Its original processing capability was entirely crude-oil based feedstock. Through the years the facility has been upgraded and beginning in 2014 is able to process up to 100% NGLs.  The primary feedstock is ethane, with lesser amounts of propane and butane.  The site will be transitioning to 100% ethane feedstock processing in late 2017 when the All Ethane conversion (COP2E)  and 2nd ethane feed line (C2FS) projects are completed.


The Corunna site's feedstock is delivered to the site by pipeline and railcar then thermally cracked to manufacture primarily ethylene, but also propylene, butadiene, benzene and other co-products.

End Products

The ethylene produced is shipped via pipeline to NOVA Chemicals' Moore and St. Clair River sites for conversions into polyethylene and to other third-party customers.
Approximately 500 employees work at the Corunna plant.
