Flow model of the solid phase of a rotary drum reactor

Abstract

In this study the flow pattern of a rotating drum reactor with internal baffles, used in the desulfurization of flue gas is analyzed at pilot scale. It is designed and built a reactor of 2.5 m in length and 0.22 m diameter and 10 cm thick which was placed eight equally spaced internal baffles. The reactor for different rotational speeds and for different solids flows is calibrated. One impulse sodium chloride forcing function is applied and measured at the exit of the same concentration for evaluating the dispersion behavior of plug flow, whereby the dispersion model whose Peclet number between 19 and 40 is adjusted, allowing assume plug flow behavior.
