Agitator is provided in a crystalliser for____________________?
Correct answer: D. All A., B. and C.
- A. Avoiding deposition on cooler surfaces
- B. Formation of nuclei
- C. Crystal growth
- D. All A., B. and C.
Explanation
Agitation keeps crystals suspended, improves heat and mass transfer, reduces deposition on cooled surfaces, and promotes controlled nucleation and growth. Therefore all three listed purposes apply.
