Two-Phase downflow liquid distribution device

摘要

A liquid-vapour distribution device for use in two-phase concurrent downflow vessels comprising a level, horizontal tray fabricated and installed so as to be essentially leak free at the junctions of the tray and the vessel wall, the horizontal tray being perforated with holes of equal size, the holes being distributed in an optimized pattern over the surface of the horizontal tray, each perforation through the horizontal tray being fitted with a vapour lift tube.
