Abstract

A method and apparatus for fluid-liquid reactions including gas-liquid and liquid-liquid reactions. The method and apparatus is suitable for mixing a fluid phase species and a liquid phase species to facilitate chemical reaction between said phases. The apparatus comprises a reactor vessel with a plurality of orificed plates and flow control means which initiates and maintains uniform mixing and efficient dispersion of a fluid-liquid mixture within the reactor vessel.

Description

technical field [0001] The present invention relates to a method and apparatus for fluid-liquid reactions. Background technique [0002] Fluid-liquid reactions can include gas-liquid and liquid-liquid reactions such as: hydrogenation, hydroformylation, oxidation, reduction, chlorination, deodorization, fermentation, and aerobic treatment; liquid-liquid reactions such as acid in aromatic nitration use of acids or bases to hydrolyze nitriles to amides; and use of acids or bases to hydrolyze amides; use of solvents in transesterification; use of molten fluids in polyurethane dispersions; and use of supersaturated fluids in gas hydrates use. [0003] Performing gas-liquid reactions in mass production is a well-known field. The above processes generally involve the use of stirred reaction tanks in which the fluids are mixed by one or more impellers located in fixed positions inside the tank with baffles. The gas is injected into the reactor by means of a sparger or spargers. ...
