Abstract
The purpose of this work is to develop a model of mass transfer inside a gas bubble during absorption processes (in particular, during absorption drying of gases) in the mode of developed turbulence, which is implemented in foam and cyclone-foam contact devices. A model of mass transfer is proposed, in which the circulation of the component inside the bubble is described by a system of toroids, which allowed to take into account the intensive mixing and vibration that affect the efficiency of mass transfer. The developed model allows us to calculate the mass transfer coefficient in a gas bubble and the overall efficiency of absorption processes. Experimental studies of the process of air dehumidification in a cyclone-foam apparatus using four absorbers with different physical properties. Experimental studies were carried out in a wide range of changes in the hydrodynamic parameters of the process, which allowed us to confirm the adequacy of the developed model to real processes.

Keywords: mass transfer, gas bubble, turbulence, cyclone-foam.
