Abstract
The article deals with the results of the experiment concerning the influence of operating conditions for vapor absorption process during air dehumidification in contact cyclone-foaming apparatus on the efficiency of the process. The efficiency was determined by both recovery coefficient and Murphree overall efficiency coefficient. It was discovered that the absorption is influenced by main hydrodynamic characteristics: air velocity, dynamic foam bed depth, the number of transfer units, and the influence of longitudinal mixing. It is suggested to evaluate general efficiency of the process taking into account on only recovery ratio, but also energy characteristics (hydraulic resistance), mass-dimensional characteristics, and the value of drop entrainment. Optimum operating conditions for cyclone-foaming apparatus during vapor absorption by dehumidifying solution are shown to be gas velocity of 5 m/s and dynamic foam bed depth of 0.3 m. The introduction of conditional efficiency coefficient allows comparing both contact apparatus and absorbents.

Keywords: air dehumidification, absorption, cyclone-foaming apparatus, efficiency, efficiency coefficient
