Abstract
The article describes the various types of preformed and random packing for heat and mass transfer apparatuses, and determines their advantages and disadvantages. It is shown that preformed moving packing is of considerable interest to the intensification of heat and mass transfer processes due to the possibility of establishing regular vortex structure in the contact zone. There are represented the results of experimental studies of hydraulic resistance, coefficient of longitudinal mixing liquid, mass transfer coefficient in the gas and liquid phases in the apparatuses both with a preformed moving sheet and ball tips. Empirical equations for calculating main hydrodynamic and mass transfer intensity characteristics have been obtained.
