ABSTRACT:
Two methods are disclosed for forming two different bubble cap assemblies for mounting over holes in tray decks of a gas and liquid contact apparatus, as a fractionation tower. The basic method comprises forming an outwardly extending annular flange on the lower end of a riser having an internal diameter substantially equal to the hole diameter, inserting an annular gasket seal having an inside diameter substantially equal to the hole diameter between the riser annular flange and the upper peripheral surface around the hole in the tray deck, forming an outwardly extending annular flange on the lower end of an inner sleeve contiguous with the inner surface of the riser and hole, inserting an annular gasket seal having an inside diameter substantially equal to the hole diameter between the inner sleeve annular flange and the lower peripheral surface around the hole in the tray deck, mounting a top spider having a sleeve therein on the riser, mounting a bubble cap on the top spider, and inserting a hold-down stud up from the bottom to protrude through the top of the bubble cap, and attaching a fastening means on the top of the hold-down stud protruding from the top of the bubble cap assembly for applying pressure to both of the annular gasket seals on the upper and under peripheral surface of the hole for assuring proper alignment of the bubble cap assembly relative to the tray deck and for providing a double seal between the tray deck and the bubble cap assembly for minimizing leakage. Additional method steps are disclosed for forming a modified bubble cap assembly.
