PARALLEL FLOW BAFFLED DOWNCOMER FRACTIONATION TRAY

摘要

THE EFFICIENCY OF MULTIPLE DOWNCOMER TYPE FRACTIONATION TRAYS IS INCREASED BY PROVIDING A PAIR OF INCLINED LIQUID DEFLECTING BAFFLES [3] OVER EACH DOWNCOMER [10] CONNECTING THE OUTLETS AND INLETS OF VERTICALLY ADJACENT DOWNCOMERS TO THEREBY PROVIDE A CIRCULAR LIQUID FLOW PATH RELATIVE TO LIQUID MOVEMENT ON EACH TRAY AND PARALLEL LIQUID FLOW ON A TRAY-TO-TRAY BASIS WHICH ACTS TO INCREASE THE LENGTH OF THE LIQUID FLOW PATH AND PRODUCE LEWIS CASE II POINT TO PLATE EFFICIENCY ENHANCEMENT.
