In a distillation column, with increase in the reflux ratio, the heat removed in the cooler ______________________?
Correct answer: A. Increases
- A. Increases
- B. Decreases
- C. Remains unaffected
- D. And the heat required in reboiler decreases
Explanation
A higher reflux ratio increases the liquid and vapour traffic in the column, so the condenser must remove more heat for the returning reflux and overhead product. It generally also increases, rather than decreases, reboiler duty.
