ABSTRACT:
The performance of multiple downcomer type fractionation trays is stabilized against the effects of any rocking motion to which the surrounding column is subjected by the provision of vapor and liquid flow control baffles on the tray deck. One such baffle is perpendicular to the downcomers and extends upward. Vertical baffles are provided within and over the downcomers. A large number of bubble-promoting devices line the periphery of the tray.
