The absorption of carbon monoxide in COSORB solutions: absorption rate and capacity

Absorption rate experiments and equilibrium experiments were carried out for the COSORB reaction at 300 K. The equilibrium data at 300 K could reasonably well be described with the following relation: [...] Determination of the kinetics and mechanism of a chemical reaction by means of absorption experiments is possible in the fast reaction regime, where the absorption rate is independent of the mass transfer. In the present study it turned out to be impossible to eliminate the influence of mass transfer, although the experiments were carried out at very low CO partial pressures. This made the determination of the kinetics and mechanism of the forward reaction of the COSORB reaction not possible. The conditions of the present experiments were such that it can be concluded that for absorption equipment design the COSORB reaction can be regarded as instantaneous with respect to mass transfer
