Abstract
An apparatus and method for mixing at least two reactants is taught wherein a first reactant is delivered to a reaction zone through a first annular flow path and a second reactant is delivered to the reaction zone through a second annular flow path. The first and second annular flow paths are concentric with one another and the two reactants intermix with one another in the reaction zone. There is a rotating disc having a surface, defining one boundary of the reaction zone. The flow of the first and second reactants across the rotating disc and through the reaction zone is generally radial and has a residence time in the reaction zone of not more than about 100 msec, and preferably not more than about 50 msec. The reaction zone resides in a main reactor vessel and there is a driven agitator residing in the main reactor vessel to stir the contents thereof.
