✦ Synopsis

Abstract

The relationship between the thermal history and the waiting time in nucleation decided for the aqueous solution of sodium chlorate was verified for the aqueous solution of copper sulfate using pilot crystallizers. The following items were clarified as the result of the experiments.

The cooling method is more stable to nucleation in comparison with the vacuum cooling method even at the same operational conditions.

The desirable effect of the thermal history is recognized only in the case in which the solution is heated up to a high degree of undersaturation.

The residence time at an undersaturated state has an important role to dissociate embryos in solution.
