Implementing of decreasing sulphur from Heavy Fuel Oil of Zakho by oxidation desulphuriation (ODS) method

In fact, all fuel oil contains a significant amount of sulfur. Because of the requirement for low sulfur content of fuel oil, it is necessary to develop alternative method for desulfurization of heavy fuel oil. Due to the disadvantage of ODS technologies such as safety , cost and easy process and green environment.new method have been developed. Elimination of sulfur compounds in this process to reach about 96%. Oxidative desulfurization method process have two-step : the number one step is reaction step where the fuel, chemicals(acidic acid and proxide and formic acid) agents and the catalyst mixing and react with each other to form sulfones, the number two step is the extraction of these sulfone combination using a solvent agent. These reactions are rather slow in nature, however, so the process usually involves some sort of additional precaution to speed it up. In this study, the mixtures were stirred with one thousand fifty RPM the speed of reaction will be increase. Finally , while the examinitation of several elements and parameters of the interaction where sulfur was totally removed from heavy fuel duly via Oxidative desulfurization method, after that outwardly: the natural sulfur content of 4.7% (w) was reduced to 2.54% (w), and for this project using H2O2 with CH3COOH yielded much better results than H2O2 with HCOOH. Another effect is quantity of oxidant amount, catalyst, and the temperature was also evaluated in terms of their effects on the performance. One interesting finding out of these inquiries was the fact that increasing the reaction temperature yielded better results up to 65 Co, where the highest efficiency in elimination of sulfur through Oxidative desulfurization method for the Zakho refiner fuel oil was achieved
