Desalter is a process unit on an oil refinery that removes salt from the crude oil. The salt is dissolved in the water in the crude oil, not in the crude oil itself. The desalting is usually the first process in crude oil refining.
Salt are naturally present in oil. When oil is distilled at a refinery, it is heated to over 800 Deg F, causing the salt to become very corrosive. To remove salts wash water is added to the crude in the incoming crude feed.
