Abstract
Many different processes are used to treat raw natural gas to pipeline quality. Sulfur is commonly present as an impurity in fossil fuels. Magnetic field is applied in a fluidized bed which contains nano activated carbon to investigate hydrogen sulfide elimination. Sulfur removal in this way is presented experimentally and theoretically. The rate of mass transfer is introduced as function of gas temperature, amount of balls covered by nano carbon tubes, initial concentration of hydrogen sulfide, gas flow rate and magnetic field. The experimental data are presented and compared with the model results. The effect of hydrogen sulfide in the inlet sour gas on the mass flow rate in investigated in this paper. In addition, the effect of porosity percentage of catalytic bed on the hydrogen sulfide content of outlet gas is evaluated in this paper. The outlet concentration below 4 ppm is acceptable result due to commercial rules. The experimental data are in higher values of hydrogen sulfide comparing with the ones from modeling data.
