摘要： 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.

摘要： An improved process for removing free liquid from a hydrocarbon-rich gas stream is disclosed. Liquid is injected into the gas stream upstream of a chiller and downstream of an acid-gas removal system and any equipment that may affect the water content of the gas stream: compressors, columns, additional knockout drums, heat exchangers or the like. This enhances heat and mass transfer in a manner that both minimizes the formation of small droplets and encourages the coalescence of small droplets in the chiller. As a result, small droplets which would normally pass through a knockout drum and a standard mist eliminator are increased in size, prior to their arrival at a vapor-liquid separator to larger drops which are easily removed by the vapor-liquid separator, and the mist eliminator.
