biggest refinery in
The Motiva oil refinery, located in Port Arthur, Texas, is controlled by Royal Dutch Shell and Saudi Aramco, the largest oil company in Saudi Arabia and in the world. Motivaâs owners recently sunk $10 billion into expanding its capacity for processing gasoline, diesel and other petroleum products. The changes also make the refinery capable of handling lower-quality heavy crude oil that Saudi Arabia has been producing recentlyâoil that most refineries canât process.
