Batch crystallization is a process used in chemical engineering and manufacturing to produce solid crystals from a liquid solution. In this process, the solution is heated until it becomes supersaturated, meaning it contains more solute than it can hold at that temperature.As the solution cools, the excess solute begins to crystallize out of the …
