Abstract

The description of a pilot plant and results of a research of intensity of a heat mass transfer are provided and hy-draulic resistance at various initial concentration of the absorbed gas and relations of an expense of the liquid absorber to a consumption of gas mixture. It is established that use of water as the absorber of carbon dioxide doesn't provide necessary effectiveness of process. At absorption of carbon dioxide from an air with an aqueous solution of monoethanol amine in the hollow vortex device, with increase in concentration of CO2 (carbon dioxide) in steam-and-gas mixture on an entrance to the device the effectiveness of the device significantly decreases and increases with the gain in the relation of mass flows of liquid and gas phases. It is noted that vortex devices are 3-5 times more effective in comparison with nozzle ones, by 2-3 times more in comparison with dish-shaped devices.
