ABSTRACT:
Phase-contacting plates are defined by a plurality of pivotable flow-blocking members arranged in alternating rows in which the respective blocking members thereof pivot in opposite direction to the respective blocking members of adjacent rows, the respective blocking members of each row overlapping successive members thereof, each blocking member being deflectable by the upward flow of the low-density phase and controlling the downward flow of the high-density phase, each flow-blocking member being formed by at least one elongated flow-blocking flap pivotable about a transverse axis at one end thereof, and at least one moment-equalizing element operatively connected with the flow-blocking flap.
