Fuels

The refineries process crude oil into different products, such as gasoline, jet fuel, asphalt and other products. The most basic process of refining crude oil separates into its various components. The crude oil is heated and placed in a distillation tower, where the various hydrocarbon components are boiled off and recovered and condensed at different temperatures.

Differences in crude oil

The physical characteristics of crude oil may be different. In simple terms, are classified by their density and sulfur content. The ("lighter") crudes generally less dense have a higher proportion of light hydrocarbons, allowing high-value products such as gasoline, jet fuel and diesel can be processed with simple distillation.The ("heavier") denser raw generate a very high proportion of low value properties with simple distillation and require additional processing to yield the desired product range. Some raw also have a higher sulfur content, an undesirable characteristic for processing and product quality.

Refineries use other compounds to oil

In addition to oil, refineries and processing plants use and add other oils and fluids for the production of the final product for consumers. These include liquids that condense in the gas wells. The plants process liquids from the natural gas, crude oil and unfinished oils produced by the partial, such as gasoline and light oils, kerosene, light gas oils, heavy gas oils and residues refining. The crude residue derived after distillation of the heavier components.
