The article is devoted to the assessment of the energy efficiency of mass transfer devices filled with chaotic placing units using an approach based on the use of the energy coefficient Е (V.M. Antufyeva). Using the Owen model of the turbulent boundary layer, taking into account the attenuation of turbulence in the boundary layer, an expression is presented for calculating the average mass transfer coefficient from the chaotic packed layer in the channel. An algorithm for calculating the energy efficiency of the channel filled with placing units for carrying out the mass transfer process is presented. In order to select the most energy efficient intensifier of the mass transfer process, several types of irregular packings have been considered. The energy coefficient E was calculated for a channel filled with placing units of various shapes, sizes, and also made of various materials. According to the data obtained, graphs of the dependence of the energy coefficient E on the Reynolds number (mode of motion) have been plotted. The advantage of the considered approach is that the process of mass transfer requires the least amount of empirical parameters about the object of modeling being studied to evaluate the efficiency from an energetic point of view.
