Abstract: A static mixer includes first and second tubular housings which define elongated internal cavities. Dividers divide each internal cavity into a plurality of separate and sequential flow paths for the fluid mixture. Each separate flow path extends between the opposite ends of each housing, reverses direction substantially adjacent to an end of each housing, and conducts the fluid mixture in a direction opposite of the fluid mixture conducted by one of a preceding or succeeding flow path.

Abstract: A carrier fluid and an added input fluid are mixed together in a static mixer to create an emulsified output fluid mixture. The static mixer comprises a plurality of mixing chambers whose cross-sectional size expand considerably relative to an inlet, a series of bent and curved baffle plates which divert, rotate, divide, reverse and otherwise create turbulence in the combined flow, and inlet chamber in which the added input fluid is dispensed upstream into the carrier fluid, and a number of other structural mixing elements which, through turbulence, abrupt pressure drops and velocity changes, subdivide the added input mixture into very small volumetric quantities evenly dispersed within the carrier fluid to create a homogeneous output fluid mixture.

Abstract: A mixing device comprising a first housing, a second housing, a swedge (or reducer), an inlet for carrier fluid, and an inlet for chemicals, wherein the ratio of the inside diameter of the first housing to the inside diameter of the second housing is in the range of 1:2 to 1:8; the change in diameter between the first and second housing is abrupt, inside the first housing are an inlet agitator and an injection nozzle, inside the second housing is a static mixer, and the swedge is connected to tubing that delivers a mixture of carrier fluid and chemical down a well bore. In an alternate embodiment, the present invention comprises two or three mixing assemblies on a frame.

Abstract: A mixing device comprising three mixing assemblies and first and second horizontal inlet arms, wherein the mixing assemblies are arranged horizontally on a frame, with one mixing assembly on the bottom, one on the top, and one in the middle of the other two mixing assemblies. Each mixing assembly comprises a first housing, a second housing, and a swedge. In a preferred embodiment, the ratio of the inside diameter of the first housing to the inside diameter of the second housing is 1:2, the change in diameter between the first and second housing is abrupt, and the first housing extends into the second housing by a certain distance. Inside the first housing are an inlet agitator and injection nozzle, and inside the second housing is a static mixer. The injection nozzle is located proximate to the point at which the change in diameter occurs between the first and second housing.
