A device for mixing a first fluid and a second fluid may include a primary conduit that may extend along a longitudinal axis of the primary conduit between a primary inlet port and a primary outlet port. The primary conduit may have a constant primary inner diameter for an entire length of the primary conduit. The primary inlet port may be connected to a pressurized source of the first fluid. The device may further include at least one secondary conduit that may extend parallel with the primary conduit. The secondary conduit may include a secondary inlet port and a secondary outlet port. The secondary conduit may have a constant secondary inner diameter. The secondary inner diameter may be smaller than the primary inner diameter. The primary conduit may encompass at least a portion of the secondary conduit. The secondary outlet portion may be disposed within the primary conduit. The secondary inlet port may be connected in fluid communication with a source of the second fluid.

An additive delivery system may incorporate a cartridge system, including a container cap and a reservoir assembly that provides for storage of an additive. The container cap includes a mixing nozzle for mixing of the additive with a base fluid as the base fluid flows from the base fluid container through the cartridge. A one-way valve prevents backflow of base fluid and/or mixed base fluid/additive from an area downstream of the mixing nozzle such that the base fluid supply remains in a pure state.

Devices, systems and methods for mixing and/or introducing agrochemicals, comprising a mixer including a mixing chamber in which a liquid is able to flow, and a delivery point located on the mixing chamber for delivering an agrochemical into the mixing chamber, wherein the mixer includes means for generating backpressure in the liquid and the agrochemical in the mixing chamber, and a mixer system including a mixer, an injector, and an agrochemical source, wherein the injector is adapted to receive an agrochemical from the agrochemical source, and a method including the steps of supplying a liquid into a mixing chamber of a mixer or mixer system, delivering an agrochemical into the mixing chamber, and generating backpressure to the liquid flowing through the mixing chamber to effect mixing of the liquid and the delivered agrochemical.

A multi-component mixing device including at least a first supply of a first product and a second supply of a second product. The mixing device has a mixing chamber having at least a first inlet and a second inlet, the first supply opening into the mixing chamber at the first inlet and the second supply opening into the mixing chamber at the second inlet. The mixing device includes a nozzle arranged and adapted to inject the second product from the second supply into the mixing chamber as a flat jet. An associated mixing method is also provided.

An adjustable additive cartridge that provides adjustable metering of additive to a base fluid as the base fluid is flowing through the cartridge. A spout is mounted for limited rotation within a base element of the cartridge. Rotation of the spout results in varying degrees of flow of additive into a base fluid flow path through the cartridge. The cartridge may be used with a portable beverage container, such as a sports bottle or off-the-shelf water bottle. The supply of base fluid in a container used with the cartridge may be kept in an unmixed, pure state, and other cartridges, each having different additives (i.e., flavors) may be used interchangeably with the same base fluid supply. The cartridge allows a consumer/user to experience different additives, such as different flavors or supplement compositions, for a given supply of base liquid in a single container. A check valve on the cartridge prevents backflow of the base fluid. An integrated filter for filtering base fluid flowing into the cartridge may be provided. The additive cartridge may be sealed to provide for extended storage and to provide a user/consumer with evidence of integrity, quality and/or tampering prior to purchase and/or use. Visual and tactile indicators of the amount of additive being added to a base fluid may be provided. A container may retain a spare additive adjustable cartridge on the container.

The present invention relates to a process for controlling the antifoam injection based on the pressure differential of the column. More specifically, the present invention relates to a process for controlling the antifoam injection based on the pressure differential of an aromatics extraction unit using an intelligent differential pressure transmitter. The controller communicates with the antifoam injection system so that the antifoam is injected to the unit only when it is required.
