Abstract
The efficiency of multiple downcomer type fractionation trays is increased by increasing the length of the liquid flow path and providing Lewis Case II point to plate efficiency enhancement. Baffles (7) extending axially along the vertical axis of a fractionation column divide the intertray volumes of the column into defined vapor passageways. A pair of inclined liquid deflecting baffles (3) over each downcomer (10) connects the outlets and inlets of vertically adjacent downcomers and provides a crisscrossing liquid flow path. Beds (14) of vapor-liquid contacting material increase tray efficiency.
