Firefighters are looking for the cause of a big, smoky fire at a Houston, Texas oil refinery Monday.

The blaze broke out Monday this afternoon in a unit that begins the process of converting crude oil into gasoline at the Lyondell-Basell Industries plant.

There are no reports of any injuries.

The plant covers 700 acres along Houston's ship channel and was one of the first refineries built in the region back in 1918.
