Some principles of modeling extraction columns with rotary vibrations of the packing
The authors studied the hydraulic and mass-transfer characteristics of columns with rotary vibrations of the packing, established the principles for modeling, and obtained the data for designing them. Studies of 40-mm-diameter columns with rotary vibrations of the packing made in the form of a shaft with vertical perforated strips showed that in the column section where the dispersed phase commences flowing, this phase moves mainly along the vertical perforate strips. An analysis of mass transfer allowing for longitudinal mixing showed that the true mass-transfer coefficient for a given system in columns with vibratory movement of packing is a function of the specific energy dissipation independent of the packing design; a reliable calculation of the effective working line of the countercurrent extraction process in the apparatus under consideration is possible by allowing for mass-transfer parameters and longitudinal mixing.
