Abstract
A method and apparatus for mixing and distributing two reactants within a column. The apparatus forms a mixing zone in the column into which a first reactant (e.g. a process stream having both gas and liquid phases) flows vertically downward. The second reactant (e.g. quench gas) is introduced into the mixing zone and flows radially to intercept the downflowing process stream. Due to the construction of the mixing zone, a torturous path is provided which thoroughly mixes the different gas phases and the liquid phase by several different mechanisms, i.e. (a) radial jet mixing; (b) perpendicular mixing of the liquid and gas phases; (c) jet/turbulent mixing; (d) high velocity swirl jet mixing and atomizing of the liquid phase; (e) turbulent swirl mixing after the liquid is atomized; (f) additional turbulent jet mixing; and (g) energy dissipation of the flow as the mixed stream is distributed radially outward across the column through first a sieve tray and then a riser tray.
