Abstract:
1. A blending apparatus for blending at least two fluid streams, wherein a first fluid stream has a first density and a second fluid stream has a second fluid density, said first density being greater than said second density, said apparatus comprising: a first fluid director comprising a plurality of baffles affixed therein to create turbulence and shear in the first fluid; a cylindrical second fluid director; a primary mixing chamber receiving the first sheared fluid from the first fluid director and receiving the second fluid from the second fluid director, wherein the first fluid and second fluid are mixed in the primary mixing chamber to form a mixed primary fluid stream; and a secondary blending chamber comprising at least one static mixer and coaxially aligned with and receiving the mixed primary fluid stream from the primary mixing chamber; wherein the first fluid director has an inner surface, and the baffles comprise: wherein the first linear baffle edge and the second linear baffle edge are parallel to each other; and wherein the upstream baffle and the downstream baffle are affixed to opposing sides of the inner surface of the first fluid director.
