Abstract
A novel one-piece tray and matching supporting ring simplify the assembly of distillation columns having multiple plates. The trays and the openings in their supporting rings, which are attached to the inner wall of the column, are in the shape of a circle interrupted by two parallel chords, the tray width between the tray chords being smaller than the circular diameter of the ring opening.
