Reactor 22 Separation-layer Micro Mixer Tube - Reaction System

4 Reactor 22 [R 22] [Separation-layer Micro Mixer Tube] - Reaction System 

Separation layer mixers use either a miscible or non-miscible layer between the reacting solutions, in the first case most often identical with the solvent used [48]. By this measure, mixing is postponed to a further stage of process equipment. Accordingly, reactants are only fed to the reaction device, but in a defined, e.g. multi-lamination-pattem like, fluid-compartment architecture. A separation layer technique inevitably demands micro mixers, as it is only feasible in a laminar flow regime, otherwise turbulent convective flow will result in plugging close to the entrance of the mixer chamber. 

Both concentric and stacked fluid layer arrangements, corresponding to difler-ent versions of separation mixers, were developed, allowing either a drop- or streamlike injection of liquids in a reaction tube attached to the micro mixer [48], 

This separation layer mixer is constructed as an assembly of stacked stainless-steel plates having three tubes [48], These tubes are placed into each other and are inserted into a fit. The plates contain three feeding lines for reactants 1 and 2 as well 

The stacked steel plates were manufactured by milling [48]. The PTFE tubes were home-made by means of turning and milling.
