Petróleo

Abstract Oil is a mixture of hydrocarbons composed of different kinds of molecules formed by atoms of hydrogen and carbon and, to a lesser extent, oxygen, nitrogen and sulfur, combined variable shape, providing differentiated the various types of raw features found in nature. Oil refining is basically a set of physical and chemical processes aiming at the transformation of this raw material in derivatives. The process is initiated by atmospheric distillation, which is the fractionation of crude oil. This operation is performed in fractionation columns, of various dimensions, which have various separation stages, one for each desired fraction. Derivatives of this fractionation are mainly gas, LPG, naphtha, gasoline, kerosene, diesel oil and atmospheric residue. Such fractions, taken along the spine in its various stages of separation, should be treated and turned into final products, or be sent as raw material for other refining processes, that will benefit.

Resumo O petróleo é uma mistura de hidrocarbonetos composta por diversos tipos de moléculas formadas por átomos de hidrogênio e carbono e, em menor parte, de oxigênio, nitrogênio e enxofre, combinados de forma variável, conferindo características diferenciadas aos diversos tipos de crus encontrados na natureza. O refino de petróleo é, basicamente, um conjunto de processos físicos e químicos que objetivam a transformação dessa matéria-prima em derivados. O processo é iniciado pela destilação atmosférica, que consiste no fracionamento do óleo
