Calumet Specialty Products Partners, L.P. is a public U.S.-based company, incorporated in 1916, which specializes in the manufacturing of naphthenic and paraffinic oils as well as aliphatic solvents and paraffin waxes. They own several manufacturing plants in Princeton, Cotton Valley, and Shreveport, Louisiana, as well as in Burnham, Illinois, Dickinson, Texas, and Karns City, Pennsylvania.
In 2001, Calumet acquired the Shreveport facility from Pennzoil-Quaker State and it is one of the only complete specialty refineries operating in the United States. The Shreveport refinery is the largest operating facility in northwest Louisiana. The Shreveport Refinery is considered the flagship refinery of Calumet.
On October 1, 2011 Calumet acquired the Superior, WI refinery from Murphy Oil USA. This Superior Refinery primarily produces fuels along with Asphalt and Bunker Fuel to the Great Lakes shipping industry allowing Calumet to diversify their product offerings. In 2013, Calumet proposed spending $20 million to upgrade a dock near the Superior refinery to transport crude oil on barges across the Great Lakes. In August 2017, the Superior refinery was sold to Husky Superior Refining Holding Corporation, a wholly owned unit of Husky Energy. This move was taken in order to focus on specialty petroleum products.
Calumet acquired Royal Purple in 2012 headquartered in Porter, Texas. It produces a wide range of high performance lubricants for nearly every consumer and industrial application.
