Detailed studies on the absorption kinetics of CO2 in aqueous solutions for small superficial liquid loadings

The absorption kinetics of CO2 in aqueous solutions for low superficial loadings have been measured with a droplet train reactor. A well defined stream of uniform droplets was exposed to an atmosphere with exactly known CO2 concentration. Based on the short gas-liquid contact time within the reactor and a sensitive volumetric measurement of the CO2 flux the analysis of CO2 mass transfer in the liquid droplets was performed for small liquid loadings.
