PERFORMANCE-CHARACTERISTICS OF A PACKING WITH BOUNDARY-LAYER TURBULIZERS .4. GAS FILM CONTROLLED MASS-TRANSFER

The gas-film controlled mass-transfer rate in a honeycomb packing, wit h stamped groove turbulizers (Turbo-Pack) which affect the region of t he boundary layer, has been studied. An equation for determining the m ass-transfer coefficient as a function of gas velocity and the geometr ical dimensions of the packing has been derived. It is found that the effect of the height of packing blocks is far less than that forecast by Zhavoronkov's equation which was derived for packings with a much h igher wall thickness. Comparison of experimental data relevant to the novel design with reference packings cited in the literature shows tha t as far as its low values of pressure drop per mass transfer unit are concerned the Turbo-Pack packing is superior to all other known packi ngs.
