Electrolyzer for Production of Environmentally Safe Functional Aqueous Solutions: Analysis of Mass Transfer in Annulus

Absorption of oxygen into water and aqueous solutions of poly(acrylamides) was studied in an absorber with a wetted sphere. The effects of changes in the liquid flow rate and the polymer concentration on the liquid side mass transfer coefficient were examined. The results are expressed by correlations between dimensionless criteria modified for non-Newtonian liquids whose flow curve can be described by the Ostwald-de Waele model.

Unified Description

Theoretical relation derived in the last study for calculation of the mass transfer coefficient in the region of not fully developed concentration profile at high Schmidt numbers has been verified experimentally. This experimental study has been devoted to measurements of the rate of benzoic acid dissolution into aqueous solutions of glycerol from the internal surface of the pipe of circular cross section in the range 933 ⪬ Sc ⪬ 225 000 and 5 000 ⪬ Re ⪬ 50 000. It has been possible to explain on basis of the theoretical model, the differences between the data of various authors and to obtain a unified description of the phenomena.

Column Process

The regularities and mechanism of adsorption of dimethylformamide and dimethylamine by industrial activated carbon in their joint presence from aqueous solutions are considered. The characteristics of equilibrium adsorption, the limiting stage, and the mass transfer coefficient have been determined. The main parameters of the adsorption column process and the mode of continuous cleaning are calculated by the method of mathematical modeling.
