Crude oil is a mixture of various hydrocarbons and is a viscous, dark brown liquid. It is very wasteful to use crude oil directly, so it is necessary to separate the components in crude oil, usually by rectification, that is, to precisely control the temperature to volatilize the components with specific boiling points. A complete crude oil distillation process, in addition to the distillation unit, is also equipped with temperature control equipment, Vacuum Pumps and other equipment. These devices are connected according to certain process pipelines, and are also equipped with automatic detection and control instruments to form an organic whole, which forms the process flow of the crude oil distillation unit.
