ABSTRACT:
High vapor and liquid capacity counterflow fractionation trays demonstrating superior turndown and performance characteristics include a number of parallel downcomers separated by planar tray decking having unique bidirectional slotted cap valve geometries. Several different arrangements of the bidirectional valves are presented. The raised trapezoids of the bidirectional valves may be arranged in two groups which each face the nearest downcomer, or arranged in lines parallel to the downcomer sidewalls such that trapezoids of neighboring rows face opposite directions. In a third embodiment these bidirectional slotted cap valves are only located in the regions of the decking sections located next to the downcomers.
