✦ Synopsis

Carbon dioxide from a mixture of COZ-NZ has been absorbed by water in gas lifts of 0.48 and O-238 cm inside diameter, 05 and 1.0 m long. The liquid phase resistance to mass transfer, which is predominant, has been calculated by a fundamental theory. The theoretical results for the single bubbles is compared to those calculated from the measured depletion of COs gas in the lift.

It has been found that, although the bubbles were small, the liquid did not fall freely over the total bubble length. A deceleration of the surface velocity at the rear end of the bubbles could be calculated from the measured wavelengths of observed ripples.

Theory and experiment could be brought in agreement by use of the theoretical argument that the absorption rate in a decelerating film is much lower than in an accelerating one.
