In the layout plan for a vacuum distillation unit, operating at 60 mm Hg, supported by a barometric condenser, the appropriate place for the location of vacuum drum for collecting the distillate will be_____________________?
Correct answer: C. At ground level
- A. 5 metres above ground
- B. 2 metres above the ground
- C. At ground level
- D. 10 metres above ground
Explanation
The vacuum drum is normally placed at ground level, while the barometric condenser is elevated to provide the liquid-leg height needed for condensate discharge under vacuum. The elevation requirement mainly applies to the condenser and its barometric leg, not the receiving drum.
