Petroleum is a mixture of hydrocarbons composed of several types of molecules formed by atoms of hydrogen and carbon and, to a lesser extent, of oxygen, nitrogen and sulfur, combined in a variable way, giving different characteristics to the different types of crus found in nature.
Petroleum refining is basically a set of physical and chemical processes that aim to transform that raw material into derivatives. The process is initiated by atmospheric distillation, which consists of the fractionation of crude oil. Such an operation is performed on fractionation columns of varying dimensions, which have several separation stages, one for each desired fraction. The derivatives of this fractionation are mainly gas, LPG, naphtha, gasoline, kerosene, diesel oil and atmospheric residue. Such fractions, taken along the column in their various stages of separation, must be treated to be transformed into final products or sent as raw material to other refining processes which will benefit them.
