Crystallization processes usually involve complex physical and chemical transformations that are sensitive to process design and parameters. Data-rich experimentation enabled by process analytical technologies provide better insight of the process.
In this example, a slow-growing crystallization system is studied with the help of EasyViewer to identify particle growth behavior. The images revealed active seed form being in-situ generated in a short time frame after seeding. The growth behavior of the crystal during cooling and antisolvent addition was used to design the crystallization process and improve filtration performance.
