Louisiana, Mo. refinery announces expansion

A local chemical refinery is expanding.

Calumet Specialty Products announced Monday that it would undertake a $50 million expansion at its plant south of Louisiana, Missouri.

The company says the expansion will add about 25 new full-time jobs to its current staff of 25.

The company's website says that it refines crude oil into customized lubricating oils, solvents and waxes used in consumer, industrial and automotive products.

Construction is expected to begin in the coming weeks.

Calumet is based in Indianapolis, Indiana. The company has facilities in Northwest Louisiana, Pennsylvania, Texas and Illinois.

It purchased the plant in Louisiana, Missouri in 2012 from Hercules Incorporated.
