Fluid flow in a simultaneous mixing, separation and teeming (Simset) reactor used for continuous desulphurization of hot metal is studied. Analytical solution for the vertical down flow has been provided in terms of Bessel functions. The results of analytical and numerical solution using fully implicit finite difference method are compared. Mass transfer coefficient is evaluated using experimental data and from theoretical considerations. The magnitude of mass transfer coefficient is similar to that in powder injection experiments but the treatment times in Simset reactor are much shorter, making it suitable for fast desulphurization.
