Abstract

The article considers a promising direction for the modernization of mass-exchange contact devices. The coefficient for evaluating the economic efficiency of packing bodies using the reduced costs for the absorption process of the i-th and reference contact device is presented. A method is given for calculating the specific energy consumption at the stage of experimental studies with a large difference in the permissible speeds for the gas phase. The relationship between the quantitative and qualitative parameters of the mass transfer process, which is its efficiency, is described. Data on hydraulic resistance, mass transfer efficiency during carbon dioxide desorption and gas saturation with water vapor are presented. Graphical dependences of specific energy consumption for the process of extracting the absorbate from the absorbent and gas saturation with water vapor are obtained. A comparative analysis of regularly-structured nozzle for energy efficiency is performed. A zigzag nozzle was selected for further research.
