ABSTRACT:
An improved tray means and an extraction zone utilizing the tray means are disclosed. The tray means comprises a tray deck, a channel means, and a weir means. The tray deck and channel means cooperate to form a fluid conduit through which fluid flows from beneath the tray deck to the weir means. The tray means is useful in cross flow liquid-liquid extraction zones, with particular applicability to extractive purification of lube oils.
