Mass transfer from a single rising bubble

Abstract

Abstract The absorption rates of carbon dioxide, ethylene, and butene from single rising bubble of equivalent diameter 0.4–2.0 cm in water have been measured using an apparatus in which the bubble volume change with time of rise can be measured. The apparatus uses techniques previously reported but also is suitable for studies of mass transfer without and with chemical reaction at higher pressures (up to 4 atmospheres). The results have been compared with theoretical equations for rate of gas solution at the frontal surface of the bubble based upon potential flow theory and Higbie theory. The data are assessed together with those of others to show that they can be correlated well by This equation is valid for bubbles of equivalent diameter 0.6 < d < 4.0 cm and within the range 500 < N Re < 20,000
