Abstract

Gas absorption experiments were carried out for the CO2-water system using an inclined plate. Liquid-phase concentration, surface velocity and thickness of liquid film in liquid flow direction were measured to clarify the relationship between mass transfer rates and flow conditions of liquid film.
Critical points were observed in the concentration curves of CO2, and the flow conditions probably can be classified into two regions (laminar and turbulent).
For the laminar region, the experimental values coincided very well with the theoretical ones of the penetration model.
For the turbulent region, the surface renewal model could be applied to reproduce the experimental results. Better correlations between the fractional rate of surface renewal, liquid Reynolds number and a factor involving the effect of plate inclination were obtained.
