Abstract

A fluid mixing device (10) for use in chemical reactions involving two or more immiscible fluid phases. It mixes the reactants and prevents phase separation, particularly in pipe bends. The device (10) for mixing fluids flowing through a pipe (16), comprises a plate (12) having a flowpath (14) therethrough and two or more tabs (20) extending from the plate into the flowpath at an angle (24) from the plane (22) of the plate. The tabs (20) are formed by first folds (32) in the plate, at least two of the tabs (20A) having a second fold (26) therein, the tabs and first and second folds being arranged to produce two counter-rotating vortices (30) in the fluids passing through the pipe. The device has a plane of symmetry (28) perpendicular to the plane (22) of the plate (12).
