Figure 3. Experimental setup of MACC (left), the classic temperature route for membrane induced nucleation and growth in crystallizer (right).
Benefited from the high-speed microscopic camera, it can easily validate the theory proposed in section 2.2 and Figure 1b. Under the experimental condition, the crystals grew to certain size on the membrane surface. Then the crystal beyond a critical size automatically slipped from the membrane surface (shown in Figure 4). This phenomenon vividly represented the induced nucleation and auto-seeding process during MACC.
