Crystallization refers to the formation of solid crystals from a homogeneous solution. It is essentially a solid-liquid separation technique and a very important one at that.

Crystallization from liquid solutions is the most important separation operation in industries especially in the pharmaceutical and fine chemicals, whereas crystallization from melt is a very powerful separation process for the purification of organic compounds up to very high purity grade, that is > 99.99%. Furthermore precipitation is suitable to produce solid products of uniform and small size.

Crystals may be organic, inorganic, or biological in origin and require ever greater control of their characteristics and quality. The industrial crystallization research by Chem Process is similarly broad, ranging from determination of crystallization kinetics to computational fluid mechanics and scale-up. With a controlled level of purity and yield, crystallization may occur during the concentration of a solution, by the reaction of chemicals or by cooling of saturated solutions.

Chem designs and manufactures the following types of Crystallizers for crystallization of diverse products:

        •  Adiabetic Vacuum

        •  Evaporative Forced

        •  Draft Tube Baffle

        •  Spray Evaporator Crystallizer

        •   Others
