<p>An assembly for transferring fluid between trays in a liquid-liquid chemical process or contact tower (12) is disclosed. The contact tower (12) contains a continuous phase (126) and a dispersed phase (128). The assembly includes first (102) and second trays (103), each having a plurality of apertures providing a flow path for the dispersed phase. The assembly further includes a tray-to-tray transfer device providing a flow path for the continuous (126) phase between the first (102) and second (103) trays. The transfer device includes an angled section (107) having a plurality of apertures (144) providing a flow path for the continuous phase near the inner surface of the angled section (107) to interact with the dispersed phase (128) near the outer section of the angled section. A contacting device for liquid-liquid contact tower is also disclosed. The contacting device includes a tray having an active area. The active area has an array of undimpled apertures and arrays of dimpled apertures on either side of the array of undimpled apertures.</p> |
