Abstract
The processes of the absorption of three different gases (helium, oxygen, and Freon-12) by water have been studied experimentally under laboratory conditions. Short glass pipes had a diameter of 12.4 mm. In order to exclude diffusion resistance in the gas phase single-component, gases were used, but not a mixture of gases. The density of the irrigation of the perimeter of the pipes (0.1–0.8 cm2/s) corresponded to the film flow regime in which entrainment is absent. During the treatment of the results, dimensionless average concentration was represented as a function of the perimeter of longitudinal coordinate \(\varepsilon = \frac{{Dx}} {{qh}} \). The estimate in terms of two-film model of mass transfer showed that the coefficient of mass transfer does not remain constant in the liquid phase, but decreases along the pipe. A calculation method has been proposed that is based on the results of the theoretical solution of the problem about diffusion in the laminar film during an ascending cocurrent.
