D. E. Garrett Associated Chemicals Co., Pomona, Calif.
Successful crystal production depends on complex relationships between many variables. Although crystallization is based partly on know-how, scientific principles should guide the process-designer
Choice of crystallization equipment is particularly important, since product quality often depends on design. Suitable applications of the most common industrial crystallizers are given here
