Ecological Systems and Devices Annotation << Back Simulating the benzopyrene adsorption process from flue gases Golovanchikov A.B. Kablov V.F. Kuryleva L.V. Dulkina N.A. A physical and mathematical simulation is given for adsorption of benzopyrene formed in natural gas combustion in thermal power station boilers. Langmuir isotherm parameters have been calculated for the equilibrium dependence of benzopyrene concentrations in the air and in the adsorbent through a similar dependence of a standard substance – benzol. Based on the material balance equation and mass transfer equation, a discontinuous adsorber calculation algorithm has been described. A table of input and reference data and discontinuous adsober calculation results as per the suggested algorithm are given and compared with the standard calculation algorithm described in the reference literature. It has been shown that the known calculation algorithm diminishes the work cycle time by 21 % with the benzopyrene concentration in the ambient air decreases to the maximum allowable concentration (MAC) and by 2.28 times when concentration decreases to the background level. Continuously operating adsorber calculation results with a dense moving adsorbent layer are given to indicate that the adsorbent utilization efficiency of the adsorption container is 2.28 times higher than that of the discontinuous adsorber when concentration decreases to MAC and 7.48 times higher when concentration decreases to the background level.
