Corunna, our largest site, is capable of producing in excess of 3 billion pounds of petrochemicals annually. Originally devoted entirely to processing crude-oil-based liquids, the facility now has the flexibility to process a much broader variety of feedstocks, producing a full range of primary petrochemicals.

Crude oil, condensate and natural gas liquids are delivered to the site by pipeline for processing. Co-products are derived during petrochemical production at the site, including synthetic natural gas, gasoline components, diesel fuel and home heating oil. Another co-product, heavy residual fuel oil, is sold as industrial fuel.

Corunna also produces a variety of specialty chemicals for the North American market. These include products for the rubber and hydrocarbon resin industries, as well as resin oils used in the manufacture of printing inks and adhesives. Our polyethylene sites – Moore Township and St. Clair River – produce polyethylene resin. Moore Site converts ethylene, supplied by Corunna, to manufacture both low-density and high-density polyethylene resin.

The St. Clair River polyethylene facility is also home to NOVA Chemicals' SCLAIRTECH™ polyethylene licensing and international ventures business. SCLAIRTECH technology is used to manufacture high-density and linear-low-density polyethylene resin.

The resin from both polyethylene sites is transported to end-product manufacturers via rail and truck in the form of small pellets. End-products produced from our polyethylene resin include grocery bags, film wrap, household bottles and foam for packaging.
