ABSTRACT:
An improved sealed-sieve tray extraction tower has pipe means located in at least a portion of the downcomer or upcomer zones, as the case may be, for delivering at least a portion of a first continuous phase through the downcomer or upcomer zone such that it is not broken into fine droplets thereby minimizing the potential for dispersion of the continuous phase.
