The present paper provides an overview of the intensification of mixing processes with complexfluids. First, mixing processes of rheologically complexfluids and their design methodology are discussed. An example of process intensification of mixing with rheologically complexfluids using a Couette-Taylorflow reactor is introduced. Second, the intensification of the mixing of a suspension with high concentration solids and a novel approach for solid-liquid separation using a stirred vessel are discussed. Finally, a perspective of the intensification of mixing processes with complexfluids is summarized.
