Filtration Properties

The filtration properties of a suspension of a sparingly soluble substance produced in a MSMPR (mixed suspension mixed product removal) crystallizer with a mean residence time tz have been studied as a function of the crystal growth mechanism. The slope, n, of the log α vs log tz plot, where α is the specific mass filtration resistance, takes values of 0, 1, and 2 for the mononuclear, diffusion, and screw-dislocation mechanisms, respectively. If solid phase coagulation occurs, n takes values below 2. For the size-dependent growth, n may become greater than 2.

Kinetics Of Crystal Growth

Kinetics of crystallization of the pentaerythritol has been determined in laboratory experiments: MSMPR (Mixed Suspension Mixed Product Removal) crystallizer experiments served for determination of the kinetics of secondary nucleation and of the kinetics of crystal growth.

Crystal Growth Mechanism

Morphological features of montmorillonite aggregates in a large number of samples suggest that they may be formed by a dendritic crystal growth mechanism (i.e., tree-like growth by branching of a growth front).
