Desirable value of absorption factor in an absorber is___________________?
Correct answer: C. > 1
- A. 1
- B. < 1
- C. > 1
- D. 0.5
Explanation
The absorption factor is A = L/(mV), and a value greater than one generally gives favorable absorption with sufficient liquid flow relative to gas flow. Values below one indicate a less favorable absorber and require more stages.
