A novel mixing apparatus and process for mixing at least two fluids are disclosed. Excellent mixing and superior pressure drop characteristics are achieved in a device comprising at least two supply channels to feed a mixing chamber and create a vortex. The alignment of the supply channels is such that fluids are introduced into the chamber at both tangential and radial directions. In the case of gas/liquid mixing, particularly advantageous is the injection of the liquid stream tangentially and the gas stream radially. When two liquid streams are mixed, it is desirable to distribute them into fine, interdigitated channels prior to introduction into a supply channel and finally into the chamber. The mixed stream is generally withdrawn from the center of the swirling vortex and in a direction perpendicular to the plane of the vortex.

Static mixer and process for mixing at least two fluids

The invention relates to a procedure and a micromixer for mixing at least two fluids. The aim of the invention is to reduce the mixing time of the micromixer compared to micromixers known to the art while maintaining high mixing quality and small structural dimensions. The inventive procedure is characterized by the following steps: a plurality of separated fluid currents of both fluids are brought together and alternately adjacent fluid lamellae of both fluids are formed: the combined fluid currents are carried away and a focused total fluid current is formed; the focused total fluid current is fed as fluid jet into an expansion chamber; and the resulting mixture is drawn off. The micromixer comprises a plurality of alternately adjacent fluid channels which open into an inlet chamber. A focusing channel is in fluid connection with said inlet chamber and opens into an expansion chamber. The inventive procedure and micromixer are especially advantageous in that they are suitable for the production of emulsions and dispersions.

Method and statistical micromixer for mixing at least two liquids

A novel apparatus for mixing and reacting at least two fluids are disclosed. Excellent mixing and superior pressure drop characteristics are achieved in a device comprising at least two supply channels to feed a mixing chamber and create a vortex. The alignment of the supply channels is such that fluids are introduced into the chamber at both tangential and radial directions. In the case of gas/liquid mixing, particularly advantageous is the injection of the liquid stream tangentially and the gas stream radially. Reaction of the fluids can take place within the mixing chamber or in a separate reactor in fluid communication with the mixing chamber outlet. The mixer/reactor apparatus is especially useful for reactions where rapid diffusion is critical.
