3.6 Conventional cooling crystallization experiment.
Conventional cooling crystallization experiment (seeding and no seeding) was carried out as the comparison test. The initial concentration, volume of the crystallization solution, the cooling curve and operation conditions were all the same as in MACC process. The seeding temperature had been optimized and was also same with MACC. The seed amount was 1.5 wt% and 0.5 wt% of the yielding products, which were also optimized one. As a comparison, the crystals produced during the conventional experiment were also tested via the same method.
