Determination of crystallization kinetics from batch experiments

Three types of batch crystallization model experiments are considered: a) crystallization in which a constant supersaturation is maintained throughout the experiment (e.g. by programmed cooling); b) crystallization during which supersaturation is produced at a constant rate; c) crystallization (e.g. by precipitation) in which an initial supersaturation produced at the beginning gradually decreases during the run. The kinetic data obtained in the first case are of the same kind as those obtained in a continuous MSMPR (mixed suspension - mixed product removal) crystallizer. The two remaining types of experiment, on the other hand, can only provide relative kinetic data with respect to a reference run.
