At high pressure CO₂ is absorbed into a solution of NaOH in a packed column. The reaction is as follows: CO + 2NaOHNaCO3 + HO with - TAl = KCACB (A) (B)

Find the rate of absorption, the controlling resistance, and what is happening in the liquid film, at a point in the column where p_A = 10⁵ Pa and C_B = 500 mol/m³. Data: kaga: = 10-4 mol/m s. Pa * KAI 1 x 10-4 m/s = a = 100 m- k = 10 m/mol.s HA 25 000 Pa.m/mol = DA 1.8 X

This problem was adapted from Danckwerts (1970).

CO + 2NaOH NaCO3 + HO with -TAL = KCACB (A) (B)
