AbstractResearch on the desulfurization of heavy crude oil will be carried out utilizing Alkalines, Oxidative desulfurization, and a combination of Alkalines and Oxidative desulfurization, among other approaches. In this study, the effects of alkaline solutions with different weights (10–30 gm), temperatures (30–60°C), contact times (30–60 min), and mixing speeds (300–500 rpm) were studied. It was revealed that the removal efficiency of the individual alkaline process was very low. A number of tests are carried out with the goal of offering a suitable technique for the removal of sulfur from heavy crude oil while taking a variety of procedures into consideration. According to the findings of the study, the combination of oxidative and alkaline desulfurization generates the best desulfurization effect, which is around 64.45 %. This is followed by oxidative desulfurization, which produces a 56.54 % desulfurization effect. A study found that alkalines removed the least amount of sulfur (39.52 %) when no oxidative desulfurization was used It is also being researched the influence of different H2O2 concentrations, treatment times, and temperatures on crude oil desulfurization when using a combination of alkaline and oxidative procedures. The results show that when the temperature and H2O2 volume ratio increase, the ultimate sulfur removal rate increases, but virtually maintains constant as treatment time increases. These significant findings will pave the way for widespread usage of combination aulkaline and oxidative desulfurization procedures.
