Founded in 1946 to process oil from the Gilbertown field, the Tuscaloosa-based Hunt Refining Company is the oldest continually operated refinery in the state of Alabama. In 2010, the refinery completed a $900-million expansion project. The expansion increased the refinery’s capacity to handle 72,000 barrels of crude oil per day and doubled the amount of gasoline and diesel fuel it is able to produce to 55,000 barrels per day.
