- In unit operations their is only physical change is occur but no chemical change take place or we can say no chemical reaction take place.
- Evaporation, Distillation, Liquid liquid extraction, Drying, Size reduction, Crystallization are the example of unit operations.
- In these operations thier is only physical change take place like phase will be change or two or more substances are separated each other or particle size will reduce.
- Unit operations are processes related to physical changes of the materials involved:
- Mixing (Solid-Solid, Solid-Liquid, Solid-Gas, Liquid-Liquid, Liquid-Gas, Gas-Gas)
- Separating (Sieving, Filtration, Distillation, Fractional crystallization, Fractional freezing, Centrifugation)
- Heating / Cooling of materials
- Transporting (Solids, Granulates, Liquids, Slurries, Pastes, Gases)
- Measuring (Weighing, Volumetrizing, Counting)
