The chemical profiles, or crude oil assays, specify important properties such as the oil's API gravity. The delivery locations are usually sea ports close to the oil fields from which the crude was obtained (and new fields are constantly being explored), and the pricing is usually quoted based on FOB ( free on board , without consideration of ...
Petroleum products are materials derived from crude oil as it is processed in oil refineries. Unlike petrochemicals, which are a collection of well-defined usually pure organic compounds, petroleum products are complex mixtures. [1] Most petroleum is converted into petroleum products, which include several classes of fuels. [2]
The use of the term paraffin in place of the standard chemical nomenclature alkane is particular to the oil industry (which relies extensively on jargon). The composition of a gasoline depends upon: the oil refinery that makes the gasoline, as not all refineries have the same set of processing units; the crude oil feed used by the refinery;
Crude oil is extracted from the ground in several processes, the most commonly seen may be beam pumps. To create gasoline, petroleum must first be removed from crude oil. Liquid gasoline itself is not actually burned, but its fumes ignite, causing the remaining liquid to evaporate and then burn. Gasoline is extremely volatile and easily ...
Each crude oil has unique molecular characteristics which are revealed by the use of crude oil assay analysis in petroleum laboratories. [83] Barrels from an area in which the crude oil's molecular characteristics have been determined and the oil has been classified are used as pricing references throughout the world.
Petroleum refinery in Anacortes, Washington, United States. Petroleum refining processes are the chemical engineering processes and other facilities used in petroleum refineries (also referred to as oil refineries) to transform crude oil into useful products such as liquefied petroleum gas (LPG), gasoline or petrol, kerosene, jet fuel, diesel oil and fuel oils.
Oil refineries are one way hydrocarbons are processed for use. Crude oil is processed in several stages to form desired hydrocarbons, used as fuel and in other products. Tank wagon 33 80 7920 362–0 with hydrocarbon gas at Bahnhof Enns (2018) The predominant use of hydrocarbons is as a combustible fuel source. Methane is the predominant ...
Petroleum naphtha is an intermediate hydrocarbon liquid stream derived from the refining of crude oil [1] [2] [3] with CAS-no 64742-48-9. [4] It is most usually desulfurized and then catalytically reformed, which rearranges or restructures the hydrocarbon molecules in the naphtha as well as breaking some of the molecules into smaller molecules to produce a high-octane component of gasoline (or ...
