The sour gas sweetening is one of the main processes in gas industrials. Since the gas sweetening is performed through chemical, so it needs high cost and energy. Therefore, Nano fluid and magnetic field were used in this research for sour gas desulfurization. The mechanism of hydrogen sulphide absorption using nano fluid in filled bed under magnetic field was investigated in this study. The current study was performed as laboratorial using mathematical model for finding the rate of sulphur in exhaust gas flow. Therefore, some related parameters for sulphur rate such as mass transfer rate and mass transfer coefficient and effective rate of mass transfer and effective coefficient of mass transfer were investigated in this research. Increasing the amount of zinc oxide nanoparticles increases the percentage of sulphur removal per unit volume of time in vitro and theory. Increasing the amount of nanoparticles of zinc oxide from 0 to about 0.013% by volume increases the percentage of removal of sulphur per unit volume of time by about 6%. Also, increasing the amount of nanoparticles of zinc oxide from about 0.013 to 0.1% by volume will increase the percentage of removal of sulphur per unit volume of time by about 10.85%. The empirical results show the increase in trend in the amount of sulphur removal per unit time with increasing nano concentration. The experimental results prove that the presence of magnetic field can improve the sweetening process, severely. This value for the determined operating conditions is about 17%.
