Magnesium hydroxide (A) solution is an efficient solvent for CO2 (B) scrubbing from refinery sour gas stream at 215 °C and atmospheric pressure. Based on diffusion experiments, it was found that DAB at that temperature is 1.23×10-6 m2/s the Henry coefficient is 3.1 ×10-2 M/atm of the gas in the solution. Most of the scrubbing occurs within the very thin layer of the A that accounts for 10 μm. For the bulk gas side, the film was 100 times thicker and the diffusivity was 103 larger. Which resistance was higher, in the gas or liquid side? Justify.

Magnesium hydroxide (A) solution is an efficient solvent for CO2 (B) scrubbing
from refinery sour gas stream at 215 °C and atmospheric pressure. Based on
diffusion experiments, it was found that DAB at that temperature is 1.23×10-6 m2/s
the Henry coefficient is 3.1 ×10-2 M/atm of the gas in the solution. Most of the
scrubbing occurs within the very thin layer of the A that accounts for 10 μm. For the
bulk gas side, the film was 100 times thicker and the diffusivity was 103 larger.
Which resistance was higher, in the gas or liquid side? Justify.
