Agglomeration diagnosis is essential in process engineering to maintain crystal size distribution and product quality in industries like pharmaceuticals and food processing. By comparing theoretical growth-only sizes with actual measurements, engineers can identify if process conditions like low shear or high supersaturation are causing particles to cluster.
