De termination of limiting gas and liquid discharge through columns with tubular contact devices

In order for the efficiency of heat- and mass-exchange columns with tubular contact devices to be elevated it is essential to determine at the design stage the limiting discharges (loads) of the gas and liquid phase with precision. The influence of the physiochemical properties of the liquid and gas on the limiting loads of the phases was studied. Distilled water, aqueous glycerin solutions, a mixture of kerosene and carbon tetrachloride, and other mixtures were tested in a laminar-wavy liquid film flow regime. The curve calculated by an equation generalized from the experimental data is compared with experimental data of other researchers. The equation makes it possible to determine by experimental calculation method the rate of flooding of a film tubular column with any geometric determination.
