Abstract
A distributor for supplying a mixed phase flow of gas-liquid feed uniformly on the surface of a trickle-bed of solid particles, including a tray horizontally arranged above the surface of the trickle-bed. The tray is equipped with a plurality of open-ended tubular distributor downcomers of a predetermined tube diameter and extend vertically for a certain height above and below the tray. The downcomers are adapted to provide passage for liquid flow through horizontal aperture in the tube wall of the downcomers and to provide passage for gas flow through the open ends of the downcomers. The apertures are disposed in the tube walls at various elevations above the tray with a predetermined minimum elevation for maintaining a liquid level on the tray.
