A multi-directional contactor apparatus configured to utilize co-current and counter current flow to contact a first fluid and a second fluid, wherein the second fluid is more dense than the first fluid. The contactor comprises a chamber partially divided by a vertically extending weir, a first inlet port permitting the first fluid to enter the chamber, a second inlet port positioned above the first inlet port and permitting the second fluid to enter the chamber. Countercurrent and co-current contact of the first and second liquids occurs on one side of the weir. The weir separates the co-current contacted second fluid stream from the countercurrent contacted second fluid stream and allows the separated streams to be released from the chamber. The co-current and countercurrent contacted first fluid is released from an upper portion of the tank.

A mixer duct for mixing of a turbulent flow includes an inlet, an outlet in fluid communication with the inlet, and at least one static mixer element located between the inlet and the outlet. The at least one static mixer element includes at least two at least substantially coplanar plate-like segments spaced apart by a substantially longitudinal gap. Each segment is attached to a duct wall and comprises at least two free edges, with one free edge being a leading edge and the other free edge adjacent to the longitudinal gap. The at least two segments are inclined relative to a duct axis so that their leading edge is oriented up-stream in the mixer duct and substantially perpendicular to a direction of a main fluid flow.

A device or system includes a mixer comprising a three-dimensional lattice defining a plurality of tortuous, interconnecting passages therethrough. The mixer is in communication with sources or streams of at least two separate components which, when mixed, form a combined fluid stream. The sources or streams may be, at least initially, on opposite sides of the mixer, or the sources or streams may be on the upstream side of the mixer with an outlet disposed downstream of the mixer. A related method may include providing a mixer comprising a three-dimensional lattice defining a plurality of tortuous, interconnecting passages therethrough, and selecting a material for the mixer based on physical characteristics of said material, said characteristics including a selected one or more of mean flow pore size, thickness and porosity volume.

A system and method for introducing a slurry mixture for making gypsum board is disclosed. The system includes, for example, a mixer, a foam injector, and a canister for mixing and moving a slurry mixture of foam and gypsum slurry. Also included in the system is an apparatus having a funnel body constructed and arranged to further mix the slurry mixture. The funnel body includes a number of baffles projecting from its inner wall towards a center and that are spaced around the inner wall. The baffles induce turbulence into the slurry mixture as the slurry mixture moves towards its outlet, thus further mixing the mixture and reducing the flow rate of the slurry mixture before its exits from the outlet for forming the gypsum board.
