Oil refineries are typically large, sprawling industrial complexes with extensive piping running throughout, which convey streams of fluids between large chemical processing units

In many ways, oil refineries use much of the technology and can be seen of as types of chemical plants.

The crude oil feed stock is typically processed at an oil production plant. There is usually an oil depot (tank farm) at or near an oil refinery for the storage of incoming crude oil feedstock as well as bulk liquid products.
