ABSTRACT:
A liquid-vapor contact column comprising an outer tubular shell and a plurality trays supported within the tubular shell to intimately contact an ascending vapor phase with the descending liquid phase. An alignment of the active portions of the trays can produce a counterflow pattern in the vapor phase, opposite to the direction of flow of the liquid phase. This results in an increased hydraulic gradient taken from the outlet to the inlet of the tray. In order to inhibit the ascending vapor phase from flowing in the counterflow direction the active portions of the trays are staggered.
