Abstract

Absorption rates of carbon dioxide into aqueous solutions of sodium phenoxide were measured using a laminar liquid-jet, a wetted wall column and a stirred tank absorber with a plain gas-liquid interface. The rate constant of the second-order reaction between carbon dioxide and sodium phenoxide solution was derived as 20.2 1/mol sec from the absorption data with the wetted wall column under the fast-reaction regime. The experimental data with three types of absorbers could be predicted by the theory of absorption accompanied by the second-order reaction, using measured physico-chemical properties and derived reaction rate constant.
