According to one aspect, the design, simulation and control of such systems is performed using computational fluid dynamics (CFD) software that is configured for determining the separation efficiency of separators on the basis of the true geometry and multidimensional flow field and for a distribution of droplet sizes with the influence of the emulsion concentration on the rheology of the oil-in-water or water-in- oil dispersion. The results of the CFD simulations can be used to adjust input parameters of the separator to maximize the separation efficiency of the separator such that it outputs liquid streams containing minimal amounts of immiscible liquid dispersions.
