After reading the journal review by Y. T. Shah et al. [AIChE J., 28, 353 (1982)], design the following bubble column reactor. Sixty percent carbon dioxide (CO2) in a flue gas is to be removed by bubbling through a solution of sodium hydroxide (NaOH). The reaction is mass-transfer limited. Calculate the reactor size (length and diameter) necessary to remove 99.9% of the carbon dioxide.

The flow rate of the flue gas is 0.05 m3/sec and the flow rate of the sodium hydroxide is 0.001 m3/sec. The reactor must operate in the bubbly flow regime, so please recommend a type of sparger to use.

 

Given:

Bubble Column Reactor

 

vL = 0.001 m3/sec

vGo = 0.05 m3/sec

vG = 0.02 m3/sec

 

 

DC = ?

HC = ?
