Material exchange column attachment - comprising flap valve between trays for rapid pressure reduction


The downcomer section between trays in the column is equipped with a movable device, which, in normal operation, is tightly closed but in case of a sudden pressure fluctuation, can open by moving into the free space between the trays. Damage to the trays due to a sudden too sharp pressure rise can be prevented as these valves allow a rapid pressure equalisation throughout the column.
