In continuous distillation, the internal reflux ratio (Ri) and the external reflux ratio (Re) are related as_____________________?
Correct answer: D. Ri = Re/(1 + Re)
- A. Ri = Re/(1 - Re)
- B. Ri = (1 - Re)/Re
- C. Ri = Re
- D. Ri = Re/(1 + Re)
Explanation
With an external reflux ratio Re = L/D and an internal reflux ratio Ri = L/V, the total condenser balance gives V = L + D. Therefore, Ri = L/(L + D) = Re/(1 + Re).
