Abstract

Overflow system for distribution of continuous phase into column, to also enable coalescence of dispersed phase, is positioned at the interface between the two phases in separator section of column. Pref. overflows are positioned slightly below interface, and form a mesh the size of which is chosen to ensure uniform distribution of continuous phase. Pref. system is used in gas/liq. contacting columns.
