✦ Synopsis

In order to assess the performance of drowning-out crystallization using a T-mixer, nucleation and supersaturation were studied. The particle size was changed considerably with the solvent fraction and the feed rate, which were the main parameters controlling the supersaturation. At S = 1.7, the boundary point between homogeneous and heterogeneous nucleations was found from a log-log plot of supersaturation rate versus maximum supersaturation. Drowning-out crystallization using a T-mixer could easily generate high supersaturations of up to 50, which were adjusted by the feed rate and the ratio of solvent to antisolvent. Nano-and micron-sized particles can be prepared by drowning-out crystallization using a T-mixer.

## Abstract A study was made on a isothermal process for the crystallization of potassium sulfate as an alternative to the cooling process. The process employs addition of 1‐propanol to aqueous salt solutions to achieve the β€œsaltingout” of the K~2~SO~4~. This work was carried out using an automated
