Abstract
Removal of hydrogen sulfide from crude oil is an important process in oil refineries that reduces the concentration of sulfur in oil. The use of nano-catalysts in the removal of sulfur from oil is a new method. The zinc nano oxide with a diameter of 54 to 91 nm has been used in sour oil refining in this study. The experiments have been performed for the catalytic separation of two samples of heavy and light oil. In this study, the effect of different operating parameters on the performance of the sweetening process has been investigated. According to the results, temperature of 55°C and pressure of 1.6 bar can be introduced as optimal temperature and pressure. In addition, zinc oxide with a diameter of 58 nm and 77 nm can be used as the optimal diameter for sweetening of heavy oil and light oil, respectively
