Web1. Dual flow trays: Gas and liquid flow in opposite directions along the same path. 2. Cross Flow Trays (shown here): Liquid flows across the trays through the rising gas. Gas passes through the bubbling area of the tray, which contain holes or other bubbling devices such as bubble caps or valves. WebThese trays and packing are the same as those used in distillation and absorption columns. Tray types include sieve, valve, and bubble cap. The geometry of the trays affects the extent and type of contact between the vapor and liquid streams. Downcomers channel the liquid flowing from one tray down to the tray below.
