<p>A vapor-liquid distribution method and apparatus utilize a bubble cap assembly (100) for attachment over an opening in a deck tray of a gas-liquid contact apparatus (e.g., catalytic reactor). The bubble cap assembly (100) comprises a riser (112) 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 bubble cap (114) encompasses an upwardly extending end of the riser. A key feature of the assembly is the provision of a dispersion plate (158) in a lower end of the riser (112) 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 (158) has a plurality of openings (162) therethrough, at least the outer openings being provided with tabs (164) to disperse the mist flow radially outward.</p> |
