| Abstract: | Absorption and desorption rate data for the system CO2-hot carbonate solutions are presented. The data are interpreted on the basis of a film-theory model developed following the procedure recently presented by Astarita and Savage 1]. The agreement is very satisfactory. Values of the kinetic constant of the rate-determining step, previously known only up to a temperature of 40°C, have been obtained up to 110°C. |
