Carbon, in the form of petroleum coke, and hydrogen may also be produced as petroleum products. Since petroleum often contains a few percent sulfur-containing molecules, elemental sulfur is also often produced as a petroleum product. Refineries also produce other chemicals, some of which are used in chemical processes to produce plastics and other useful materials. Heavier (less volatile) fractions can also be used to produce asphalt, tar, paraffin wax, lubricating and other heavy oils. These fuels include or can be blended to give gasoline, jet fuel, diesel fuel, heating oil, and heavier fuel oils. The largest share of oil products is used as 'energy carriers', i.e. The majority of petroleum is converted to petroleum products, which includes several classes of fuels.Īccording to the composition of the crude oil and depending on the demands of the market, refineries can produce different shares of petroleum products. Unlike petrochemicals, which are a collection of well-defined usually pure chemical compounds, petroleum products are complex mixtures. 'Petroleum products are useful materials derived from crude oil (petroleum) as it is processed in oil refineries. It was drawn using data from the chart on the California Energy Almanac website. This divided bar chart sample shows the petroleum products yielded from 1 barrel of crude oil in California in 2004.

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. 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.Īn oil refinery is considered an essential part of the downstream side of the petroleum industry.'

The crude oil feedstock has typically been processed by an oil production plant. In many ways, oil refineries use much of the technology of, and can be thought of, as types of chemical plants. Oil refineries are typically large, sprawling industrial complexes with extensive piping running throughout, carrying streams of fluids between large chemical processing units. '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.
