Abstract

The invention disclosed herein is concerned with a process for mixing a plurality of viscous rapidly reacting, fluid materials and an apparatus with which to perform this process. In this process the fluid materials are initially introduced into a mixing chamber and mixed with a gas, preferably in such a way that an angular momentum is imparted to the mixture. The mixture is then fed into a static mixer which has a short residence time spectrum. The apparatus comprises a cylindrical mixing chamber with a gas inlet and at least one nongaseous fluid material inlet arranged to direct flow tangentially to the interior surface of the mixing chamber. Other inlets may be provided downstream of these initial inlets but before a static mixing apparatus with which said mixing chamber communicates. An outlet is provided downstream of said static mixing apparatus which preferably has intersecting baffle plates, a low pressure loss and a short residence time spectrum.
