A novel fractionation tray (1) includes slidable decking plates (4) located between and alongside parallel downcomers (2). The decking plates located between a pair of downcomers have sections which may be extended outward toward the edge of the tray to adapt the shape of the tray to the internal shape of the column in which it is installed. A method of installing the trays, with an upper tray being supported only by a lower tray, is also disclosed.

Adjustable circumference fractionation tray and method of installation

Fractionation trays are provided with an antipenetration pan which intercepts liquid falling from the downcomer of a vertically superior tray. The antipenetration pans are supported above the surface of the lower tray by brackets attached to the tray decking and to a horizontal deck brace which extends across the tray deck at the location of a joint or splice between adjacent tray deck plates. The invention thereby provides a simple, low cost and easy to install integral antipenetration pan and tray splice construction.
