The Filtration Equation for Packing Material

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

“…The results of experimental studies of packing devices in hydrodynamics of a singlephase filtration flow through the packing layer are shown in Figure 2 (filtration curve 1). Its further processing with the classification criterion dependence λ=f(Rem) described in detail in [44,45] allows predicting the effective industrial use of any packing materials samples. The developed classification technique λ=f(Rem) is especially relevant in the conditions of processing and comparison of large amounts of experimental data and in particular in multiple studies of waste samples from machine-building enterprises (metal shavings).…”

“…Table 1. Results of processing the experimental data by the classification method λ=f(Rem) [44,45] for packing material in the form of metalworking wastes from machine-building enterprises (S-Aisi 316Ti material, specific surface 400 m 2 /m 3 , porosity 0.82 m 3 /m 3 Based on the analysis of the obtained data ( Figure 3) according to the classification criterion dependence λ=f(Rem) the studied packing material occupied the operating range by the Reynolds modifying number from 0.137 to 1.16; and by the hydraulic resistance coefficient λ from 16.49 to 3.72 which corresponds to the absorption process.…”

The experimental study of increasing the efficiency of emulsion separation

“…One of these methods is the study of various inserts, to be installed inside of settling tanks, which have the form of webs, shields and other geometric bodies that increase the velocity of water-oil emulsions stratification into components by changing the flow structure when skirting the obstacles. It should be noted that nowadays the flow rate of water-oil emulsions in settling tanks does not exceed few millimeters per second, since at higher velocities the efficiency of emulsions separation significantly decreases due to the mixing of phases [10][11][12][13][14][15][16][17][18][19][20].…”

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 .…”
