Oil is the oil out of the ground consists of materials

Oil is the oil out of the ground consists of materials that can be burned for it is a great source of fuel and Mhzh ingredients are often in the form of a mixture of ingredients Aloadrockerbonih It is also useful in plastic materials, rubber, plastics and fibers at the refinery by this material. Oil refining is done by extracting compounds that we want to use it and turn it different for our products of fuel and other terms not Imkkna use crude oil extracted from the ground directly, and refining is done by cracking crude oil from the oil to the original components of Alkrbot molecules and hydrogen, is then re ranking within refineries and processing of materials usable, whether gaseous, liquid or solid. And processes that are the refineries are three major operations in the following sequence: 1) physical separation processes: and is done by several methods initially by distillation process, which is the separation of low-molecular boiling by boiling and condensation, by vacuum distillation devices under the pressure of the so-called pressure Almakhlkhal Zbzasith primary atmospheric distillation devices, is produced by these processes liquefied petroleum gas and gasoline or gasoline and produces diesel fuel, kerosene, lubricating oils and asphalt. The second method is a method of extracting materials by solvents and where the separation of materials by a certain boiling temperatures used in distillation, each according to the size of molecules and weight, this is done by using propane and Alforvural and solvent phenol and solvent benzene, toluene and the most important product of this process is the heavy lubricating oil. The third way to install a cooling using gasoline operations and the separation of gases and knowledge of the number of gasoline Zaladd PFOA PFOA fuel and Alcetana number of diesel, and the resulting wet gas and dry gas. 2) chemical conversion processes: and carried out through several ways. First the manufacturing operations of the material by heat and are beginning by thermal cracking using small and large olefins and disarmament of hydrogen to form aromatics and then condensing these aromatics to form coke compound, after Coke compound formation method is used Coking to extract the compound Cook petroleum, and gases are dealt with on the way a process called Balbaroleezz. The second method is to use the Catalytic cracker operations and the third way is to reform fossil raw gasoline with Alozmrah interactions. 3) and purification treatment processes: to be made by removing hydrogen sulfide and mercaptans removal vehicles and purification using hydrogen.
