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 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.
A petrochemical refinery in Grangemouth, Scotland . 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]
[4] [5] The crude oil feedstock has typically been processed by an oil production plant. There is usually an oil depot at or near an oil refinery for the storage of incoming crude oil feedstock as well as bulk liquid products. In 2020, the total capacity of global refineries for crude oil was about 101.2 million barrels per day. [6]
Petroleum oil refinery, which converts crude oil into high-octane motor spirit (gasoline/petrol), diesel oil, liquefied petroleum gases (LPG), kerosene, heating fuel oils, hexane, lubricating oils, bitumen, and petroleum coke; Edible oil refinery which converts cooking oil into a product that is uniform in taste, smell and appearance, and stability
The Los Angeles County refinery was ranked as the top emitter of nitrogen and selenium among 81 oil facilities in 2021, a recent study found. Study of U.S. oil refineries ranks Chevron El Segundo ...
A typical fluid catalytic cracking unit in a petroleum refinery. Fluid catalytic cracking (FCC) is the conversion process used in petroleum refineries to convert the high-boiling point, high-molecular weight hydrocarbon fractions of petroleum (crude oils) into gasoline, alkene gases, and other petroleum products.
The processing of crude oil can result in the joint products naphtha, gasoline, jet fuel, kerosene, diesel, heavy fuel oil and asphalt, as well as other petrochemical derivatives. The refinery process has variable proportions depending on the distilling temperatures and cracking intensity.
