Absorption cleaning of ventilation emissions

Abstract

Abstract Various methods are used to clean industrial ventilation emissions: mechanical, electrical, absorption, thermal, catalytic. Absorption methods are economically justified when the concentration of impurities in the gas stream is more than 1 %, which are present in the vent emissions of technological industries. The main element of the absorption cleaning systems is the absorber, the design and technological parameters of which determine the entire layout of the gas cleaning system. For the proper selection and calculation of the absorption treatment scheme, it is necessary to know the production technology, equipment, where emissions are generated in excess of the norms of maximum permissible concentration, as well as the properties of process flows. Using the universal modeling program ChemCad allows reducing the time for calculating the thermodynamic and physicochemical properties of flows, increase their accuracy and eliminate errors when choosing treatment equipment at industrial enterprises. The results of the study were proposed when designing a scheme for the absorption cleaning of ventilation emissions in the production technology of paint and varnish products or the technology of production of drywall.
