System for generating a discrete liquid phase in a continuous liquid phase

Abstract

The device () serves for the generation of a discrete liquid phase in a continuous liquid phase with a first or a second liquid. The two liquids coexist as separate phases, have different densities and permit a desired exchange of material. Provision is made to arrange the device in a container () which contains the second liquid forming the continuous phase. The device includes a distribution member (), in particular a cylindrical tube, and a collection passage () for the first liquid in a horizontal longitudinal extent. The collection passage has an outlet side (), a collection side () and at least one side wall () connecting the outlet side and the collection side. The side wall establishes a connection between the outlet side and a horizontal drip edge (). This side wall has a shape and an inclination which enables the formation of a liquid film of the discrete liquid phase. For enhancing the stability of the Film, the side wall () can have a good wettability for the first liquid. The drip edge or the side wall preferably have a profiling, in particular a toothed arrangement () for the generation of the discrete phase in the form of drops which are preferably of an equal size due to a uniform toothed arrangement.
