EFFECT OF PHASE FLOW-RATES ON SEPARATION IN A COUNTERCURRENT CRYSTALLIZATION COLUMN

The dependences of the separation efficiency of a countercurrent cryst allization column, longitudinal concentration distributions, and the h eight of transfer units on phase flow rates (capacity) are studied exp erimentally and theoretically. It is found that a sharp increase in th e rates of heat transfer and phase transformations in a certain zone o f the column makes the process more stable to an increase in the flowr ates: even a large increase in the flowrates fails to cause a consider able decrease in the separation efficiency.
