Oil refining

Means the processes by which the oil is processed, extracted the required carbon materials, and converted into a consumable form, by breaking its molecules and remaking them with a new chemical structure.

Major oil refining operations

Physical separations

In which the particles are separated using distillation towers, where each substance is separated at its boiling and condensing temperature, or by using coolants that separate the heavy materials from the oil components by refrigeration, or using chemical solvents.

Chemical conversion processes

It is a process to improve the quality of the extracted materials, as in physical separation processes, by performing chemical processes under the influence of heat, pressure, and cofactors, and by using the carbonization method, where heat and high pressure are used to break down heavy particles of the extracted petroleum in the distillation process, to produce a better and purer quality And, the coking process is used to produce coke from the remaining materials from the thermal cracking process, and as catalysts are used, in order to break down at high temperatures, without the need to generate high pressure.

Processing and purification processes

It is the process of purifying petroleum products from unwanted impurities, such as sulfur materials and others, which lead to damage to the devices that burn them, and these operations are carried out in more than one stage, including:
  • Filtration of hydrogen sulfide by removing hydrogen sulfide, which is an unpleasant odor and unwanted substance, which is either the same as the raw material itself, or it is caused by the different chemical processes in the above mentioned refining.
  • Filter the compounds of the two compounds, which are the removal of these unpleasant, unpleasant odor compounds, using caustic soda solutions if they are light-boiling compounds below 100 ° C, and if they are heavy compounds, they are disposed of using desalination processes by converting them into harmless H2S .
  • Hydrogen purification by converting harmful sulfur substances that corrode into minerals into hydrogen sulfide compounds.
