Additives of Base and Acid to Oxidative Desulphurization Process of Al-Sumoud Refinery at NRC Baiji

The removal of sulfur compounds from kerosene via extraction is based on the fact that sulfur compounds are more soluble than hydrocarbons in appropriate solvents. The most attractive feature of extractive desulphurization is its applicability at low temperatures and low pressure. The kerosene samples used in this research were obtained from the North Refineries Company, Baiji (NRC), Al-Sumoud refinery. Production of high-quality kerosene fuel decreases its sulphur content of it, and thus burns with the least amount of CO2. One of the main risks to the combustion properties of kerosene and to the atmosphere is the presence of secondary pollutants, such as sulfur and other impurities. Sulfur contamination produces a strong odor that may cause problems if not removed. In this study, additives were incorporated into kerosene to reduce the sulfur content and improve its fuel properties. In this research, the best temperature of removal was 70 °C for base and acid, the removal average of sulfur was from 1880 ppm, while the removal average of sulfur was from 1600 to less than 600 ppm for the Al-Sumoud refinery, without effect on the other specifications, especially specific gravity is considered the main property, ruler test.
