Analysis of the Efficiency of Technologies for Extraction Carbon Dioxide from Combustion Products

The main purpose of the article is to compare and analyze existing technologies for extracting carbon dioxide from combustion products in relation mini-CHP plants operating on local fuels. presents a brief overview technical features implementation extraction gas mixtures. specific limitations each methods are shown. Mathematical modeling technological processes adsorption, physical chemical absorption carried out basis Aspen Hysys Adsorption software packages. When processes, composition characteristic actual conditions an energy source wood chips was considered, while adsorption process, simulated by binary mixture nitrogen with molar content 11 89 %, respectively. results numerical research that were obtained have shown highest degree 97 it achieved optimal mode technology. With same method, purity resulting observed, viz. 86 % taking into account water vapor 99 if dry. least effective technology method fixed bed, which dry 79 %. Therefore, practical use deep utilization fuels, obtain low impurities, necessary apply absorption. bed can be used reduce emissions or cases where does not matter.
