ABSTRACT:
A process for achieving a uniform flow profile of very viscous liquids when flowing through tubes or reaction chambers, wherein the very viscous liquid is passed through annular spaces extending concentrically with increasing diameter over the entire cross-section of the tubes or reaction chambers and having the same depth in the direction of flow, and this procedure is repeated once or several times, the annular spaces being staggered with respect to each other as viewed in the direction of flow, and an apparatus consisting of a combination of two or more discs arranged at axial intervals within a tube transversely to the direction of flow, each disc consisting of a plurality of ring-shaped bands of increasing diameter, the bands being arranged freely of one another and concentrically at intervals on a grid supporting means to provide correspondingly concentric open spaces between the bands over the entire cross-section of the tube, with the walls of the bands running parallel to the direction of flow, and the bands of the separate discs being staggered with respect to each other as viewed in the direction of flow.
