Cooling crystallization is used, as opposed to evaporative crystallization used in a plant. The experiments were performed with an initial slurry density of 27.8 kg/m 3; whereas in a chemical plant much higher crystal densities are required to operate economically. Further, the bench scale reactions are carried out at room temperature.

The GEA Melt Crystallization systems cool a crude liquid melt to create a driving force for the formation and growth of pure crystals. The suspension-based process distributes the crystal growth over a massive surface in the crystal suspension that provides the slow optimum growth rates needed to allow pure crystal formation even in relatively impure melts. By combining this …

Our experiments showed that the amount and rate of antisolvent addition were important for the crystallization; however, the stir rate and the amount of bridging liquid were the most critical factors. We successfully scaled up this process to a 300 L pilot plant reactor, keeping a constant power per unit mass during scale-up.
