Modelling and Calculation of Industrial Absorber Equipped with Adjustable Sectioned Mass Exchange Packing

Theoretical aspects and experience of using the mathematical modeling and computerized simulation technology for solving the problems of installation and repair of process equipment of chemical and petrochemical industries are considered in this scientific paper. Computational model of restoring process to working condition of pipeline section has been developed. It is shown that if you use the developed model, then the labor-intensive installation activities, related to the repair works on heat and power networks of chemical industries, can be performed in a more efficient way.

“…The packing elements are of a spiral structure and have fins and micro-roughness on their surface due to plastic deformations of the metal being treated after contact with the cutter. Experimental studies have shown that such geometric features of metal shavings samples (packing elements) provide the development of hydromechanical regimes and the intensification of mass transfer processes [39,40]. These are exactly the properties which are desired to be developed while studying new mass transfer contact devices but in this case they are generated naturally as industrial wastes appearing in large quantities at machine-building enterprises during the mechanical processing of metals by cutting.…”

“…These packing materials can undoubtedly be effectively applied in industries as packing contact devices in environmental processes for cleaning gas emissions especially in small absorption columns. The authors have focused attention precisely on processing of stainless high-alloy steel grades as they have resistance to weathering, chemical resistance, acid resistance, corrosion resistance, sufficiently high mechanical strength and, in some cases, high elasticity which depend on the composition [39][40][41][42]. One of the packing material samples will be considered in detail.…”

The paper covers the prospects to use industrial wastes from machine-building enterprises, appearing while machining various steel grades, as packing materials for industrial absorbers for environmental cleaning processes of gas emissions. The article provides obtained and processed in the criterial way experimental data in hydrodynamics of a packing material sample from metal working machines wastes appearing while treating Aisi 316Ti steel bars; packing material according to the classification method for processing experimental data λ=f(Rem) is oriented to the absorption process during selective gas cleaning in environmental equipment. The authors have compared the studied packing material to the packing that are widely used in industries. The authors have studied the main experimentally confirmed hydrodynamic effects indicating the high efficiency of the proposed packing material. The authors have made calculations for a small-sized industrial absorber for cleaning gas emissions with the use of the studied packing material.

“…Automatic sectional adjustment of catalyst layers allows adjusting the system with the high-precision and influencing the chemical reactions directly in the process. To implement automatic adjustment catalysts are required to have volume elastic properties [31][32][33][34]. 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.…”

“…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.…”

The paper provides a new approach to the high-quality implementation of gas-liquid and catalytic gas-and liquid-phase reactions in displacement reactors. The authors have described the scheme and algorithm for automatic control of the parameters of the catalyst layer. The authors have developed algorithms (mode) for automatic adjustment of the hydrodynamic and thermal modes of the catalytic section and also the principle of automatic adjustment of the system to a gradual or impulse adjusting mode which in case of liquid-phase reaction products results in active dispersion and mutual mixing of reaction products and sharp activation of hydrodynamic and diffusion processes. The article also covers the main requirements for elastically deformable catalytic layers and the advantages of using metalworking machines wastes as adjustable catalyst layers which will have a very significant environmental effect within the recycling and remarketing program.
