Abstract
Elimination of hydrogen sulfide gas H 2 S is the main aim of crude oil processing. This is done to decrease the amount of hydrogen sulfide that is present in large quantities in crude oil and reacts with water molecules to form sulfuric acid (H 2 SO 4). It is a compound that leads to extreme and quick corrosion of metals particularly iron. It is important to perform the treatment process in order to prevent damage to the equipment since transportation of oil produced depends on equipment that is made of metal and the majority of the infrastructures required in the processing unit, including pipelines and pumps, is made of iron. Experiments carried out in the laboratory using crude oil of the Kirkuk oil field showed that the desulfurization process was effective in reducing the levels of hydrogen sulfide making the oil quality and safety improved. This study has highlighted the importance of additional developments in desulfurization processes in order to comply with strict environmental standards at the lowest possible operation cost. Research in the future must be aimed at enhancing the scalability and commercial feasibility of alternative desulfurization methods in areas with high sulfur content of the crude oil.
