An analysis of interaction by exchange with the mean micromixing model is extended to a process involving elementary chemical reaction between two species and subsequent crystallization of product in a continuous mixed suspension mixed product removal crystallizer. Two specific feed conditions are considered : premixed and unpremixed feeds are considered. The sensitivity of these two cases to several parameters like the Damkohler number, micromixing parameter, fractional flow rare, and dimensionless inlet concentration of excess reactant is explored. Both reaction and crystallization performance characteristics are significantly influenced by the feed conditions. Results for the case of premixed feeds tend to suggest that the model description may be better suited to a nearly segregated configuration.
