Experimental and computer simulations of the chlorate cell

A numerical model that takes into account the three transport mechanisms of the majority of the participating species, in the chlorate process is presented here. The model does so through considering the variability of convection and not using an approximated or assumed diffusion layer. Results from the model showed that the total current density decreased along the length of the anode, and that its distribution became more extreme at lower velocities. It was concluded that the increase in concentration overpotential, was responsible for the shape of the total and by-reaction current density distributions. Finally, the model indicated that it is the hypochlorite ion that partakes in the major by-reaction, and not the hypochlorous acid molecule. An experimental cell was built and proved that the model was reasonable, especially at medium velocities.
