Abstract
The results of the study of a new contact tray for a diabatic distillation column that is recommended for use in the wood chemical industry are presented. The presented tray has low metal consumption, hydraulic resistance and holding capacity combined with high separating one. The device includes a packing to provide a cross current flow of vapors located in coaxially mounted perforated cylinders, above which a heat exchanger device and profiled plates are placed to perform a partial condensation and evaporation. The efficiency of the tray is investigated with a respect to the concentration of volatile components in the mixture and its hydraulic resistance. The intensity of an ethanolwater vapor mixture condensation on the surface of a heat exchanger coil and on the surface of horizontally mounted plates of a tray has been studied. The equations for calculating the values of the heat transfer coefficients are established. The evaporation of volatile components from the surface of the plates is investigated, and dependence is obtained, that makes it possible to estimate the consumption of vapors from the surface of the plate and the specific heat load of condensed vapors under the plate. The concentrations of ethanol in rising vapors and condensate along the height of the tray is shown. A reduction of a metal consumption, holding capacity, flow resistance and efficiency has been achieved in comparison with the adiabatic countercurrent column.
