Abstract
Fossil fuels make up the bulk of the world’s energy consumption today. One of these fuels is natural gas condensate, which is composed of various carbon compounds and is used as one of the main fuel sources. But these condensates also contain sulfur compounds such as hydrogen sulfide, thiols (citrate), and aromatic compounds that are considered environmental pollutants. Therefore, these sour hydrocarbon sources need to be refined to reduce the sulfur content. In this study, desulfurization of natural gas condensate extracted from the gas field of southern Iran and removal of disulfide oils produced in the South Par refinery was performed by hydrogen-desulfurization ion desulfurization ion with the help of hydrogen. For this simulation, the Aspen Plus software package was used. Unused hydrogen in the effluent is hydrated by washing with an amine solvent to reduce operating costs. Refined condensates are a mixture of complex hydrocarbon compounds called petroleum fractions classified according to their boiling point range. A multi-component distillation system is also simulated to produce optimal products. The cuts taken from the distillation section include boot, light naphtha, heavy naphtha, kerosene, and gas oil. This study aimed to investigate the number of sulfur compounds remaining in these hydrocarbon sections. The results of this experiment show that the final products are completely pure and free of sulfur compounds.
