Perforated plate towers are unique for solvent extraction because, they provide_____________________?
Correct answer: C. Repeated coalescence & redispersion of the drop phase
- A. Higher contact area
- B. Better contact of the phase
- C. Repeated coalescence & redispersion of the drop phase
- D. None of these
Explanation
Perforated plates repeatedly break up, coalesce, and redisperse the dispersed drops as they pass through the plates. This repeated renewal of the interface makes option c the distinctive advantage for solvent extraction.
