Refluxing of part of the distillate in a fractionating column is a 'recycling operation', aimed primarily at_______________?
Correct answer: C. Product enrichment
- A. Heat conservation
- B. Yield enhancement
- C. Product enrichment
- D. None of these
Explanation
Returning part of the distillate as reflux increases liquid-vapour contact and gives repeated enrichment of the more volatile component. Thus, reflux is primarily used to improve product enrichment or purity, not mainly to conserve heat.
