The amount of steam required per unit quantity of distillate in case of steam distillation will be reduced by __________________?
Correct answer: C. Both A. and B.
- A. Raising the temperature
- B. Lowering the total pressure
- C. Both A. and B.
- D. Neither A. nor B.
Explanation
Steam consumption per unit distillate falls when the organic component contributes a larger share of the total vapour pressure. Raising temperature and reducing pressure generally favour this condition in steam distillation, so both changes reduce the required steam.
