REACTOR FOR CARRYING OUT A REACTION BETWEEN TWO NON-MISCIBLE FLUIDS OF DIFFERENT DENSITIES

摘要

The invention relates to a reactor for carrying out a reaction between two non-miscible fluids of different densities, comprising: an inner chamber formed by a cylindrical, vertically orientated elongated casing, a base and a cover, wherein the inner chamber is divided, using fittings, into a back-mixed zone, a zone for limited back-mixing preferably arranged below the back-mixed zone, and a bungplug-type through-flow zone, wherein at least one of the fluids can flow through same after one another, wherein the back-mixed zone has `at least one inlet and the bungplug-type through-flow zone has an outlet, and the back-mixed zone has at least one mixing element which is selected from a stirrer, a jet nozzle and means for injecting the fluid with the lower density; a first cylindrical built-in element which extends in the inner chamber in the longitudinal direction of the reactor, which separates the zone for limited back-mixing from the bungplug-type through-flow zone, and which has a first through-opening to the back-mixed zone and a second through-opening to the bungplug-type through-flow zone; a second built-in element which separateds the back-mixed zone from the bungplug-type through-flow zone such that there is no direct fluid connection between the back-mixed zone and the bungplug-type through-flow zone; and back-mixing-inhibiting third built-in elements in the form of filling bodies, structured packing or fluid-permeable bases, which are arranged in the zone for limited back-mixing. The reactor permits an optimum dwell time distribution in the reaction of the two non-miscible fluids of different densities. The invention also relates to a method for carrying out a continuous reaction in the reactor.
