Continuous column crystallizers
Results obtained from the continuous operation of a two inch-diameter column crystallizer and scale-up considerations involved in the design of a four inch column are presented. Implications of a mathematical model for continuous column crystallizers are discussed, including countercurrent flow of reflux liquid phase and crystal phase, leading to a reduction in salt concentration in liquid adhering to the crystal. The factors discussed include speed of crystal transport and superimposition of oscillatory motion, column length and attitude, feed location in column and the effect of product to feed ratio. Variations in crystal rate are considered and diffusion and mass transfer coefficients calculated. A value for the optimum crystal production rate is derived.
