GRAPHICAL SOLUTION OF THE MATERIAL BALANCE CONSTRAINT FOR MSMPR CRYSTALLIZERS

This study shows how the material balance constraint may be incorporated into the semilog plotting method for mixed-suspension, mixed-product-removal (MSMPR) crystallizers. It is shown that a more accurate estimate of the crystallization kinetic parameters will result for MSMPR data if the self-consistency check is solved simultaneously with the exponential size distribution. This can be carried out graphically if the tangency curve is drawn on semilog paper and the straight line estimate is chosen as a tangent to this curve. Using specific population densities, np//cK//v/M//T, or specific cumulative number oversize, Np//cK//v/M//T, generalized graph paper can be prepared that is directly applicable to all MSMPR crystallization results.
