Gas adsorption into a liquid, such as a removal of CO₂, can be enhanced by adsorption into a reactive liquid, such as ethanolamine solutions. Consider the wetted wall column analyzed in Subsection 6.4.2. Assume that A, which is dilute, now reacts in the liquid with a first-order reaction that depends on the concentration of A in the liquid. Derive an expression for the rate of mass transfer analogous to Eqs. (6.4.13) that includes the reaction rate. What new dimensionless group characterizes the effect of reaction on the rate of mass transfer? Derive an expression for the enhancement of the rate of mass transfer (rate with reaction divided by rate in the absence of reaction)
