Abstract

A static mixer conduit comprising a longitudinally elongated conduit having tabs that are arranged with respective first edges adjacent the conduit wall, and respective opposed second edges that are spaced radially inwardly from the conduit wall. These tabs redirect fluid flow to introduce a radial cross-flow component to the longitudinal flow of fluid through the conduit. A
central body extending generally coaxially along at least a portion of the longitudinal extent of the conduit defines between it and the conduit wall, an annular space confining the radial cross-flow.
