What is a typical oil product yeild out of a barrel of crude oil?

The typical barrel of crude oil produces about 50% gasoline, about 30% diesel, and about 20% other byproducts.





The byproducts include LPG (liquified petroleum gases) such as propane, butane, and residual fuel oils. Residual fuel oils are are often consumed as asphalt (roads and roofing materials) or for low sulfur fuel oil used in ships and industrial boilers. Often these residuals are thermally cracked (broken down into smaller molecules using heat) to produce more gasoline, diesel, and a final byproduct known as petroleum coke. Petroleum coke is often burnt as a fuel source in cement kilns that convert rock to cement for use in concrete.





Oil varies widely in composition, and prices for a barrel of oil also vary widely depending on the source and composition of the oil. Oil's viscosity is measured by API gravity and heavy oil is often around 25 or less, while light gasoline-like oils are often above 40 or 50 API. Heavier crude contains less of the components needed to make gasoline or diesel (so of course it is less valuable). Sulfur contents of oil make it ';sweet'; (0-0.5%) or ';sour'; (1-10%) and oil refineries remove the sulfur creating the major source of sulfur in the market.





The sulfur is used in compounds such as rubber, cellophane, and rayon, and is used to manufacture sufuric acid. Sulfuric acid is the largest consumed commercial acid in the world, and its principal use is for extracting phosphates used in agricultural fertilizers.





Refineries are often built to refine a specific crude oil ';slate'; and do not have much flexibility to use oil that does not fit their specifications.

if you talking about what is in crude oil.............


crude oil is made by decomposing plants and animals
