Abstract: Systems and methods provided herein relate to a fluid mixing device for a pipeline. The pipeline includes a pipe wall and a first axial bore that extends from an inlet of the pipeline to an outlet of the pipeline for conveying a pipeline fluid through the pipeline from the inlet to the outlet. The fluid mixing device includes a fluid source operable to supply a mixing fluid to the axial bore through one or more orifices fluidly coupled to the fluid source. The one or more orifices include a first orifice. The first orifice includes an intake portion operable to receive the mixing fluid and defining a first interior diameter, a discharge portion operable to discharge the mixing fluid and defining a second interior diameter smaller than the first interior diameter, and a taper portion intermediate the intake portion and the outlet portion.

Abstract: A jet-mixer for a fluid mixing system includes a housing including a mixer port formed in an inner surface of the housing, and a rotor rotatably disposed in the housing, the rotor including a rotor blade, wherein the rotor includes a first angular position in the housing restricting fluid flow through the mixer port, and a second angular position allowing fluid flow through the mixer port, wherein, in response to rotation of the rotor in the housing, the jet-mixer is configured to inject a first fluid jet through the mixer port into the passage of the fluid conduit that has a pulsed velocity profile.

Abstract: A mixing apparatus and method of mixing additives are described herein. The mixing apparatus comprises a mixing conduit having a wall, a first end, and a second end opposite the first end. A fluid inlet is formed in the wall between the first end and the second end. A fluid outlet is also formed in the wall between the first end and the second end. An injection conduit fluidly connects the fluid inlet with the fluid outlet. A pump is disposed to pump fluid in the injection conduit. An additive conduit is fluidly coupled to the injection conduit.
