ABSTRACT:
A distillation or absorption column tray whose characteristic frequency is a specific function of the radius of circular apertures in its bottom wall, of the surface tension of the body of liquid therein at the operating temperature of the column and of the density of such liquid. This reduces the amplitude of vibrations of the tray under the action of ascending vapors and/or gases and hence increases the useful life of the tray.
