PETROLEUM PRODUCT

PETROLEUM PRODUCT

A petroleum is processed in a refinery product using petroleum as a raw material. Depending on the composition of crude oil and demand, refineries can produce different petroleum products.

Most of the oil is used as feedstock for energy, for example gasoline. Also produce chemicals that can be used in chemical processes to produce plastic and / or other useful materials. 

Because the oil containing 2% sulfur, large amounts of it is obtained. Hydrogen and carbon in the form of petroleum coke can also be produced as petroleum.

ORIGIN OIL

ORIGIN OIL

It is of fossil origin, the result of the transformation of organic matter from zooplankton and algae deposited in large quantities in anoxic zones of lakes or seas of the geological past, were later buried under heavy layers of sediment. 

They originated from the remains of plants and microorganisms buried for millions of years and subject to various physical and chemical processes. The chemical transformation (natural cracking) due to heat and pressure during diagenesis occurs in successive stages from bitumen increasingly lighter hydrocarbons (liquid and gas). 

These products rise to the surface, because of its lower density, due to the porosity of sedimentary rocks. When the geological circumstances that prevent this rise (oil traps as impermeable rocks, anticlinal structures, margins of salt diapirs, etc.) are then formed oilfields occur.

Oil is a homogeneous mixture of organic compounds, primarily hydrocarbons insoluble in water. 

Also known simply as crude oil or crude oil. 

It occurs in the interior of the Earth, transforming the organic matter accumulated in sediments in the geologic past and can accumulate in natural geological traps, from which it is extracted by drilling wells.

It is common to measure the volumes of liquid petroleum in barrels (42 US gallons, equivalent to 158.987294928 liters), and the volume of gas in cubic feet (equivalent to 28.316846592 liters); in other regions both volumes are measured in cubic meters.
