Ecological Systems and Devices Annotation << Back Analysis of Filtration Flow Velocity Fields in Modeling and Calculation of Environmental Mass-Exchange Equipment for Treatment of Gas Emissions and Liquid Discharges from Industrial Enterprises. Part 2. Gas Adsorption Merentsov N.A., Golovanchikov A.B., Topilin M.V., Persidskiy A.V., Anokhin D.A. Main methods of stabilization of velocity fi elds and fl ow structures of mass exchange products in working volumes of ecological mass exchange equipment are considered. The results of experimental studies of the fi elds of fi ltration fl ow of the gas phase fl ow through the active carbon layer (AG-5) with the subsequent output to the parameters of the diffusion model are presented. The results of mathematical modeling and calculation of the main technological and geometric parameters of the industrial adsorption apparatus for cleaning gas emissions from acetone vapors by active carbon AG-5 according to the diffusion model of the flow structure are presented. Keywords: modeling of mass-exchange systems, mass transfer, environmental equipment, sorption, adsorption, sorbent granules, hydrodynamics, gas dynamics, filtration, filtration flows, flow structure, Peclet criterion, velocity profile, velocity fields.
