Kinetics and modeling of carbon dioxide absorption into aqueous solutions of piperazine
چکیده انگلیسی

In this work, the kinetics of the reaction between CO2CO2 and aqueous piperazine (PZ) have been estimated over the temperature range of 298–313 K from the absorption data obtained in a wetted wall contactor. The absorption data are obtained for the PZ concentrations of 0.2–0.8kmolm-3 and for CO2CO2 partial pressures up to 5 kPa. A coupled mass transfer-kinetics-equilibrium mathematical model based on Higbie's penetration theory has been developed with the assumption that all reactions are reversible. The model is used to estimate the rate constants from the experimental data for absorption of CO2CO2 in aqueous PZ. The estimated rate constants of this study are in good agreement with those reported in the literature.
