High pressure at the bottom of a distillation tower handling heat sensitive materials results in _____________________?
Correct answer: B. Thermal decomposition of bottoms
- A. Increased relative volatility
- B. Thermal decomposition of bottoms
- C. Erosion of the tower
- D. Very efficient operation
Explanation
High pressure raises the boiling temperature of the bottoms liquid, increasing its exposure to severe thermal conditions. Heat-sensitive materials may therefore undergo thermal decomposition, even though pressure itself does not increase relative volatility.
