Experimental plant for studying hydrodynamics and heat and mass exchange processes in packing contact devices

Abstract

The paper provides a description of the developed experimental plant for studying hydrodynamic and heat and mass exchange processes in packing devices of all kinds of configuration, examples of the obtained data and original classification methods for processing experimental data. The authors describe hydrodynamic characteristics allowing carrying out classification studies and obtaining the necessary data to complete the developed methods for calculating mass exchange devices: the retaining capacity of packing devices at liquid and gas phases in particular. The authors provide the criteria function X=f(Rem) which gives a direction for industrial application of packing contact devises. The function is based on the analysis and generalization of the experimental data obtained in express studies of single-phase filtration curves. The paper also covers an example of the experimental data of the response function in case of recognizing flow structures of contact phases which allow obtaining necessary data to complete the developed diffusion models of mass exchange processes and implement calculations of mass exchange packing with a high precision.

The use of industrial wastes from machine-building enterprises as packing materials for small-sized absorbers for gas emissions purification

“…The authors will consider the results of experimental studies of a packing material sample in comparison to packing contact devices that are widely used in industries. The characteristics of heat and mass transfer packing contact devices have been studied at the experimental a detailed description and capabilities of which are presented in [39,43]. Fig.…”

The determination of hydraulic resistance during laminar filtration through layers of sorbents and ion-exchange granules in environmental mass exchange equipment

“…Filtration flows are used in many industrial processes and products of various branches of mechanical engineering, in technologies and equipment of the chemical industry and related industries [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17]. Filtration is used in water treatment processes and in environmental technologies .…”

Sectional automatic adjustment of catalyst layers in gas and liquid phase reactors

“…In addition, the catalyst should provide a developed contact surface with reaction products, and the reaction mass, in turn, should actively wash the surface of the catalyst giving an impulse to a chemical reaction. All these requirements are accumulated in the catalysts layers in the form of pressed sections of metal shavings (metalworking machine wastes) [31][32][33][34][35][36][37][38][39][40][41]. Moreover, the shaving materials themselves can be catalysts or catalysts can be applied to their developed ornate surface.…”
