The mechanism of sulphur absorption by nano fluid in a packed bed under the magnetic field is considered, in this study. The experimental and theoretical investigation is done to obtain the outlet amount of sulphur in gas stream. Experimental results show, increase in initial concentration under the higher emerged temperature caused by magnetic field increases the effective mass transfer coefficient from 2.1 to 7.9. In addition, changing 0.1 mol/m³ in the initial concentration of hydrogen sulfide increases mass flow rate effective factor from 2 to 5.9. This shows the positive effect of magnetic field on the amount of gas absorption. The experimental results show, emerging 1.5 (A) current around the vessel affects aluminium oxide nano particle which is dissolved into the nano fluid only. In addition, changes in the amount of initial concentration of hydrogen sulphide at constant inlet temperature of 40 C and gas flow rate of 0.22 m³/min is positively. In addition, the increase in the effective mass transfer coefficient is obtained and indicates on the increase in the amount of difference between magnetic mass transfer coefficient and simple mass transfer coefficient.
