ON THE CONTROL OF CRYSTAL SIZE IN A SEMIBATCH CRYSTALLIZER

Optimal programming of input flow rate to a solventing-out batch crystallizer was studied to find the maximum or the minimum average particle size while keeping the total amounts of solventing-out agent and crystals constant. For salt-water-ethanol system the maximum difference of average particle size was calculated to be about 20 percent. The difference was confirmed by experiment. The maximum difference was found by model calculation to become very large for a limited range of birth functions.
