The underlying tray is of the type supported within the chemical process tower by a support ring which is positioned beneath the edge of the tray for the support thereof. The solid support ring typically forms a nonactive area beneath this region of the tray and the tapered downcomer discharges liquid directly onto the inactive region wherein the remaining portion of the tray can be utilized for mass transfer.
