During the absorption of HCl gas in water (to produce liquid HCl), the gas is kept above dew point to__________________?
Correct answer: B. Avoid corrosion
- A. Increase the rate of absorption
- B. Avoid corrosion
- C. Reduce the cooling water circulation rate
- D. None of these
Explanation
Keeping HCl gas above its dew point prevents condensation of acidic moisture on equipment surfaces, thereby reducing corrosion. It is not primarily done to increase absorption or reduce cooling-water circulation.
