Achieving the Target Crystal Size Distribution in the Case of Agglomeration and Breakage for Batch Cooling Crystallisation Process

Achieving the Target Crystal Size Distribution in the Case of Agglomeration and Breakage for Batch Cooling Crystallisation Process

One of the main specification of crystallisation process is the crystal size distribution (CSD). In order to achieve the desired CSD, supersaturation or temperature control is applied to maintain the concentration or temperature at the required set-point trajectory which lies within the metastable...
