ABSTRACT:
This invention pertains to a liquid-gas contacting tray or plate of the sieve type. A plurality of segment zones are established on the tray each having approximately the same area and flow path length. Vertically extending baffles are established within the segment zones to define smaller stages, the baffles being arcuate in shape and of constant radius. A plurality of perforations appear in the floor of the segment zones for vapor passage. By virtue of the establishment of small segment stages of similar length and width, the liquid flow paths, gradients, etc. remain equal and inefficiencies due to local variations in liquid to vapor ratio are minimized.
