"An oil refinery or petroleum refinery is an industrial process plant where crude oil is processed and refined into more useful products such as petroleum naphtha, gasoline, diesel fuel, asphalt base, heating oil, kerosene and liquefied petroleum gas. Oil refineries are typically large, sprawling industrial complexes with extensive piping running throughout, carrying streams of fluids between large chemical processing units. In many ways, oil refineries use much of the technology of, and can be thought of, as types of chemical plants. The crude oil feedstock has typically been processed by 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.
An oil refinery is considered an essential part of the downstream side of the petroleum industry." [Oil refinery. Wikipedia]
The PFD example "Process flow diagram - Typical oil refinery" was created using the ConceptDraw PRO diagramming and vector drawing software extended with the Chemical and Process Engineering solution from the Chemical and Process Engineering area of ConceptDraw Solution Park.

Flow process chart is used in quality control to display the action sequence of physical or manual process.
Flow process chart is useful for recording actions and documenting the production process.
Flow process chart helps to analyze and improve the process steps.
Flow process chart is more preferable than flowchart for documenting the mostly sequential processes.
Three types of flow process charts include: 1) man-type charts depicting the person actions, 2) material-type charts displaying the actions with product or material object, 3) equipment-type charts visualizing the useage of tools and equipment.
The set of symbols used in the flow process charts was developed by the American Society of Mechanical Engineers (ASME).
