The Scotford Upgrader is a part of a larger site known as Shell Scotford located 40 km northeast of Edmonton, Alberta. Shell Scotford comprises three operating units: the Upgrader, a Refinery, and a Chemical plant. The Scotford Cogeneration Plant is also located on the site. Currently, work is being done on the first Upgrader expansion. In 1984, Shell opened both the Refinery and Chemical plant on the Scotford site. As one of North America's most modern and efficient refineries, the Scotford Refinery was the first to exclusively process synthetic crude oil from Alberta’s oil sands. Benzene that is produced during the refining process is sent to the adjacent Chemical plant and is used in the production of Styrene Monomer, a chemical needed to make many of the hard plastics people use daily. In 2000, a glycols plant was opened at Scotford Chemicals. Much of the output of the Scotford Upgrader is sold to the Scotford Refinery. Both light and heavy crudes are also sold to Shell's Sarnia Refinery in Ontario. The rest of the synthetic crude is sold to the general marketplace.
