Abstract
The liquid-phase mass transfer coefficient kL for a single CO2 bubble rising through liquid in a closed tube was measured by observing the change of pressure within the bubble due to gas absorption into the liquid. The bubble volume was large enough to form a slug, an elongated bubble whose motion is governed by the tube walls. Water and aqueous solutions of glycerol, giving a range of viscosity from 10−3 to 1.6 Pa s, were used, and also aqueous CMC solutions, all in tubes of diameter from 13 to 51.5 mm. The results are correlated by Sh = 0.75Pe0.5 where Sh = kLD/
