Evaporator crystallizer for Ammonium chloride

Forced Circulation Crystallizer

For applications where high rates of evaporation are required, where there are scaling components, or when crystallization must be achieved in solutions with inverted solubility or relatively high viscosity, the ZONTEN Forced Circulation Crystallizer is the best choice.

This type of unit, also known as the circulating magma crystallizer or the mixed suspension mixed product removal (MSMPR) crystallizer, consists of a body sized for vapor release with a liquid level high enough to enclose the growing crystals. Suction from the lower portion of the body passes through a circulation pump and a heat exchanger and returns to the body through a tangent or vertical inlet. The heat exchanger is omitted when adiabatic cooling is sufficient to produce a yield of crystals

The most common use of this crystallizer is as an evaporative crystallizer with materials having relatively flat or inverted solubility. It is also useful with compounds crystallized from solutions with scaling components.

Controlled supersaturation

When the heat exchanger is used, it is normally one or two pass and is designed for relatively low temperature rises in the solution. This limits the supersaturation of scaling components when heating materials of inverted solubility. In most applications, the steam to liquid, delta T is also limited to prevent mass boiling within the tubes or vaporization at the tube wall.

Forced circulation is the most widely practiced method of crystallization. FC crystallizers are found in sizes ranging from 2 foot diameter laboratory models to over 40 foot diameter units for continuous processing. Per pound of product, it is ordinarily the most inexpensive type of equipment available, particularly when substantial amounts of evaporation are required.

Forced Circulation Crystallizers can be operated on a batch basis but their most frequent use is for continuous processing of such materials as Sodium Chloride, Sodium Sulfate, Sodium Carbonate Monohydrate, Citric Acid, Monosodium Glutamate, Urea and similar crystalline materials.
