ABSTRACT
The primary objectives were measurement of kinetic rate data for the absorption of carbonyl sulfide(COS) in the secondary amine, diethanolamine(DEA), important for future modeling and design purposes. The reaction rate between COS and 5~25 wt% solutions of DEA at 25, 40, 60 and 75'C has been measured using a wetted sphere absorber. All the obtained rate measurements can be described by a zwitterion mechanism analogous to the mechanism widely accepted for the reaction between CO2 and primary and secondary amines. It was found that the overall reaction rate was entirely determined by the zwitterion deprotonation rate.
Keywords: COS | diethanolamine | wetted sphere absorber | zwitterion mechanism
