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 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.
A market developed for fuel oil as it was discovered that petroleum was superior to coal in powering the large engines of ships and railroad locomotives. The prevalence of the automobile in the early 1900s created a mass market for gasoline, and a shortage soon developed of the lighter gasoline fractions of crude oil.
An oil refinery or petroleum refinery is an industrial process plant where petroleum (crude oil) is transformed and refined into products such as gasoline (petrol), diesel fuel, asphalt base, fuel oils, heating oil, kerosene, liquefied petroleum gas and petroleum naphtha.
Catalytic reforming is a chemical process used to convert naphthas from crude oil into liquid products called reformates, which are premium "blending stocks" for high-octane gasoline. The process converts low-octane linear hydrocarbons (paraffins) into branched alkanes (isoparaffins) and cyclic naphthenes , which are then partially ...
This provides Chevron income from transporting its fuel, operating gas stations, and refining crude oil into petroleum products. The integrated approach helps mitigate some of the impacts of oil ...
Marketing of natural gas, as well as operating a gas-to-liquids plant. The Downstream segment engages in: Refining crude oil into petroleum products. Marketing crude oil, refined products, and ...
Since crude oil generally contains only 10-40% of hydrocarbon constituents in the gasoline range, refineries typically use an FCCU to convert high molecular weight hydrocarbons into smaller and more volatile compounds, which are then converted into liquid gasoline-size hydrocarbons. Byproducts of the FCC process also include other low molecular ...
