Abstract
A vapor-liquid distribution method and apparatus utilize a cap assembly for attachment over an opening in a deck tray of a gas-liquid contact apparatus (e.g., catalytic reactor). The cap assembly comprises a riser located over the opening in the deck tray, and providing fluid communication from an upper surface to a lower surface of the deck tray. A cap encompasses an upwardly extending end of the riser. A key feature of the assembly is the provision of a dispersion plate in a lower end of the riser which provides a flow restriction for two phase fluids flowing through the riser to produce a mist flow of the two phases. Preferably, the dispersion plate has a plurality of openings therethrough, at least the outer openings being provided with tabs to disperse the mist flow radially outward.
