Achieving New Scales: The First Successful Pilot Plant Spherical

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.
