With increase in solvent rate, the number of transfer units, NtoG, for a fixed degree of absorption from a fixed amount of gas________________?
Correct answer: B. Decreases
- A. Increases
- B. Decreases
- C. Decreases linearly
- D. Remain unaffected
Explanation
A higher solvent rate provides a larger liquid-side capacity and usually increases the absorption driving force throughout the column. The required number of transfer units therefore decreases for the same gas removal.
