Imperial's Sarnia operation is the most integrated fuels, lubricating oil and chemicals manufacturing and petroleum research facility in Canada.
Fuels Manufacturing
When the Sarnia refinery was commissioned in 1897, it was the largest refinery in Canada, with a capacity of 900 barrels of crude oil processing a day. Today, the refinery is one of the most complex in Canada. Since the mid-1980s, significant improvements at a number of process units have increased the refinery's ability to process a wide range of crude oil into quality petroleum products.
In the 1990s, Imperial spent approximately $17 million to reduce sulphur in diesel and benzene in gasoline. Since then, has invested more than $300 million in its Sarnia and Nanticoke refineries to produce low-sulphur gasoline. A pipeline link between the two refineries was completed in 2003. Through this innovative approach of integrating the two refineries, we began to produce gasoline with less than 30 parts per million sulphur more than a year ahead of the 2005 legislated deadline. In 2006, Imperial began producing ultra low-sulphur diesel with less than 15 parts per million sulphur, 97 percent lower than previous grades.
Lube Oil Manufacturing and Packaging
In 2000, a $100 million expansion of the lubricating oil manufacturing units used to produce the new-generation of engine oils was completed. Base oil and waxes produced by the lubricant manufacturing complex and other sources are blended with additives to create more than 250 lubricating oils, specialty products and waxes. Approximately 60 percent of the blended products are transported to customers by tank trucks and rail cars. The remaining volume is pumped to the site's packaging plant to be put into small containers.
Chemicals Manufacturing
Imperial's chemical division is one of Canada's largest producers of petrochemicals. The first unit to produce pure chemicals from petroleum was built in 1957.
The gas cracker produces ethylene, propylene and butylene olefins using natural gas liquids as well as light saturated hydrocarbons from the Sarnia refinery's coker and catalytic cracking units as feedstock. The aromatics unit uses leading technology to recover benzene, toluene and xylene from Sarnia and Nanticoke refinery feedstocks. These products are the primary petrochemicals used in the manufacture of solvents and coatings. A number of capital and operational changes have been made at this plant since 1999 to further reduce benzene in gasoline. Despite the increase in production of benzene, emissions have been reduced by 85 percent since 1997.
The polyethylene plant began operation in 1983 and continues as one of the most cost-competitive facilities of its kind in the world. A pelletizer was installed in 1986 and upgraded in 1997. The plant completed its fifth expansion in 2002, more than tripling its original production capacity to 450,000 tonnes a year.
Imperial is a founding member of the Sarnia Lambton Environmental Association, an internationally renowned industrial cooperative, devoted to environmental protection. The manufacturing site's emissions routinely meet government requirements and quality limits.
