Agitated film evaporator is suitable for concentrating _____________ liquids?
Correct answer: A. Viscous
- A. Viscous
- B. Foaming
- C. Very thin
- D. Corrosive
Explanation
Agitation continuously renews the liquid film and prevents excessive residence time, making an agitated film evaporator particularly suitable for viscous liquids. Foaming liquids generally require other specialised evaporator arrangements.
