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 1.8 billion pounds of ethylene and up to 2.0 
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 liquid. 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 facility can also utlize smaller amouts of light naphtha if economically viable.


The Corunna site's feedstocks are delivered to the site by pipeline and railcar. . These products are the feedstocks used to manufacture ethylene, propylene, butadiene, benzene and other productxylene.
