The Laurel refinery has been in operation since the 1930s. The original owner, Independent Refining Company, operated the refinery until Farmers Union Central Exchange, Inc. (CENEX, Inc.) purchased it in the 1940s. In 1998, CENEX Inc. merged with Harvest States Grain to form Cenex Harvest States
Cooperatives and subsequently changed its name to CHS Inc.
Currently, the refinery produces about 60,000 barrels per day of refined petroleum hydrocarbon products, including propane, gasoline, burner fuel, diesel fuel, asphalt, propane de-asphalted pitch, and road oil.
