The packing of an existing absorption tower is replaced with a new type of packing. The height of the packing and the inlet conditions are maintained the same as before. Tests reveal that the number of transfer units is lower than before. This indicates that the tower with the new packing, when compared to
that with the old packing, will
that with the old packing, will
- a)have a higher rate of absorption of the solute from the gas stream
- b)have a lower rate of absorption of the solute from the gas stream
- c)have the same rate of absorption of the solute from the gas stream
- d)have a lower height of transfer unit
Correct answer is option 'B'. Can you explain this answer?

Introduction:
In an absorption tower, the packing plays a crucial role in the efficiency of absorption. When the packing is replaced with a new type, it can have an impact on the rate of absorption of the solute from the gas stream. The number of transfer units is a measure of the efficiency of mass transfer in the tower.
Explanation:
When the number of transfer units is lower with the new packing, it indicates that the tower with the new packing will have a lower rate of absorption of the solute from the gas stream. This can be understood through the following points:
1. Definition of Number of Transfer Units:
The number of transfer units (NTU) is a dimensionless quantity that represents the ratio of the driving force for mass transfer to the resistance to mass transfer. It is a measure of the efficiency of mass transfer in a column or tower.
2. Relationship between NTU and Rate of Absorption:
The rate of absorption of the solute from the gas stream is directly proportional to the number of transfer units. A higher number of transfer units indicates a higher rate of absorption, while a lower number of transfer units indicates a lower rate of absorption.
3. Comparison of Number of Transfer Units:
In the given scenario, it is mentioned that the height of the packing and the inlet conditions are maintained the same as before. However, the tests reveal that the number of transfer units is lower than before. This implies that the new packing has a lower efficiency of mass transfer compared to the old packing.
4. Implication on Rate of Absorption:
Since the rate of absorption is directly proportional to the number of transfer units, a lower number of transfer units indicates a lower rate of absorption. Therefore, the tower with the new packing will have a lower rate of absorption of the solute from the gas stream compared to the tower with the old packing.
Conclusion:
In conclusion, when the number of transfer units is lower with the new packing, it indicates that the tower with the new packing will have a lower rate of absorption of the solute from the gas stream. This implies that the efficiency of mass transfer is reduced with the new packing, leading to a decreased rate of absorption. Therefore, the correct answer is option 'B' - the tower with the new packing will have a lower rate of absorption of the solute from the gas stream.
