abstract

The paper, discusses one of the important problems associated with environmental pollution due to the entrainment of liquid droplets from the mass transfer apparatus together with chemically hazardous elements. Experimental studies have been carried out and graphical dependences of the change in the value of the relative spray loss on the gas flow rate and irrigation density for three types of zigzag regularly-structured packing have been obtained. The influence of the dimensions of the triangular cell of the packings and the separation space on the size of the spray loss is described, and the most effective variant of their installation in the mass transfer apparatus is determined. A technique for calculating unknown coefficients of the empirical regression equation is presented. Equations for determining the relative spray loss are obtained. The relative error has been calculated. Recommendations are given on the operation of packed mass transfer apparatus at maximum fictitious speeds.
