20080277260 | FLUID DISPERSION UNIT ASSEMBLY AND METHOD - A tray valve assembly for a process column of a type wherein a first, heavier fluid flows downwardly from a downcomer onto a tray and thereacross in a first direction through which a second, lighter fluid flows upwardly therethrough for interaction and mass transfer with the heavier fluid before passing therefrom. A plurality of valves disposed across a surface of the tray and mounted above a plurality of apertures on the surface of the tray, each valve of the plurality of valves comprising a top surface and at least one securement leg. A first securement leg of is adapted to intercept the heavier fluid flow in the first direction forming a diverting baffle for engaging the heavier fluid flow across the tray. Each valve includes at least one aperture to facilitate the lighter fluid flow therefrom and further comprising a first aperture in the first securement leg. The first aperture is adapted to allow the lighter fluid to flow in a second direction to interact with the heavier fluid flow in the first direction for lighter fluid aeration thereof. Each valve includes a plurality of open side regions for allowing ascending lighter fluid flow to pass outwardly therefrom in generally oppositely dispersed directions for contact with the heavier fluid flow in the first direction and each valve is adapted to allow the ascending lighter fluid flow to pass outwardly therefrom generally in the first direction of the heavier fluid flow passing over the top surface for facilitating a propulsion of the heavier fluid flow therefrom and across the tray. | 11-13-2008 |
20100288624 | ACTIVATED HINGE-JOINT - A fractionation tray for use in a process column. The fractionation tray is of a type where a first fluid flows downwardly from a downcomer onto the fractionation tray and across the fractionation tray in a first direction. A second fluid flows upwardly through the fractionation tray for interaction with the first fluid. The fractionation tray includes an upper tray section, a lower tray section that is operable to removably engage the upper tray section, a joint region which includes an area of overlap between the upper tray section and the lower tray section. The joint region allows passage of the second fluid therethrough. | 11-18-2010 |
20120024977 | FLUID CONTACTOR-DIFFUSER TRAY ASSEMBLY - A separations tray assembly for use in a fluid-fluid exchange column. The separations tray assembly is of the type where a first fluid, in a continuous phase, is directed across successive trays in a serpentine flow path. A second fluid, in a dispersed phase ascends through apertures in the tray thus inducing interaction and mass transfer with the first fluid. In accordance with one aspect of the present invention, the separations tray further includes a diffuser skirt, having apertures disposed therein, operatively coupled to a fluid channel. The diffuser skirt is operable to direct the first fluid to cover substantially an entire volumetric cross-flow window between successive separations trays and to induce stirring and mixing of the first fluid and the second fluid to effect efficient mass transfer. | 02-02-2012 |
