An '''oil refinery''' is an [[industrial]] process plant that transforms raw [[crude oil]] into usable [[fossil fuel]]s, lubricants, and chemical feedstocks. These sprawling complexes serve as the downstream link in the [[energy]] sector, operating continuously through extensive networks of piping, furnaces, and distillation towers. | An '''oil refinery''' is an [[industrial]] process plant that transforms raw [[crude oil]] into usable [[fossil fuel]]s, lubricants, and chemical feedstocks.
