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.

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.

HYDROGEN SULFIDE REMOVAL FROM BIOGAS USING DIGESTER EFFLUENT ABSORBENT IN A CONTINUOUS VERTICAL COLUMN. Gas-Liquid mass transfer is one of the most commonly used phenomena in the chemical process, such as absorbtion. This research evaluates the value of liquid phase mass transfer coefficient of hydrogen sulfide removal from biogas in a continous contactor column for digester effluent-biogas system. This study was carried out by contacting biogas at certain flow with digester effluent continously in a counter-current flow packed bed column. Samples were taken in steady state condition. This research used raschig rings, large balls, and small balls as packing materials with surface areas are 0.9269 m2/m3, 0.6279 m2/m3, and 0.2992 m2/m3 respectively at volumetric flow rates of biogas from 0.1109 m3/h to 0.8846 m3/h. The results show that the relationship between the variables and mass transfer coefficient gives following mathematical model This model is valid in the range of (As·dt) and (Vg/dt·DL) respectively from 0.03 to 0.09 and from 237,267.08 to 3,307,522.67. Average error is 17.85%.

Air–water mass transfer of hydrogen sulfide from a shallow tank with a quiescent surface under the influence of weak wind stress on the water surface was studied numerically using a two-dimensional model. The flow field in the tank was investigated using a computational code based on a finite volume, which is used to numerically solve momentum, mass and continuity conservation equations. The results show that water phase flow field is strongly dependent on the wind-induced surface velocity and the aspect ratio of the tank. Based on the numerical study, the liquid-side mass transfer coefficient is correlated with Reynolds number (Re), tank aspect ratio (AR) and Schmidt number (Sc). Overall mass transfer coefficient (KL) values extend further downstream as the Re number increases.
