Porous Plastic Packing for Heat and Mass Transfer Processes

Abstract

The results of hydraulic tests of porous plastic packing for accomplishing heat and mass transfer processes are reported. The tests were carried out in a column with a rectangular cross-section of 125 × 125 mm using 10 × 10 × 2 mm porous plastic Raschig rings. The test results were used to derive graphical and analytical relationships that allow assessment of the hydraulic resistance of the sprayed porous plastic packing for different spray densities under different hydrodynamic column operation conditions. A comparative analysis of the reduced resistance coefficient was made for different types of dry packings from modified Reynolds similarity number.
