Review: Parametric Study on the Performance of Progressive Cryoconcentration System

Abstract

Progressive cryoconcentration (PC) is gaining acceptance in solution concentration process as it could provide an easy separation and ice purification with relatively low energy. In fact, the advantages of PC process as compared to the other concentration methods have led the growth of related studies that aim to provide the best system or condition for the separation process involved. Apart from the provision of appropriate equipment, the PC process should also be conducted at its optimum conditions of operating parameters involved, which could give the highest separation efficiency. Hence, relationship between the parameters, which covers both manipulated and determinant parameters should be studied first. This review summarizes the previous conducted studies on the effect of various operating parameters on the PC performance, which includes effect of coolant temperature, solution flowrate, initial solution concentration, freezing time, ice crystal front growth rate, and stirring rate.
