Petrochemical refineries convert crude oil into petroleum products. The crude oil is distilled and separated into different streams, producing end products like gasoline, chemicals, waxes and oils. While each refinery is unique, they all incorporate a variety of separation and purification processes to produce their products.
Because refinery production processes are so diverse, the water utilities that support these processes result in a wide variety of wastewater streams, both from processing streams and non-processing streams like sanitary sewage and storm water. Refi nery wastewaters require creative, thoughtful and effective treatment strategies.
