An exemplary embodiment includes a blending chamber having a urea inlet, a blending chamber gas inlet, and a blending chamber outlet. A urea source provides a pressurized urea solution to the urea inlet at a urea injection pressure, and a pressurized gas source transmits pressurized gas to the blending chamber gas inlet via a passageway. The passageway is configured to decrease pressure of the pressurized gas transmitted along its length from a first pressure of gas received from the pressurized gas source to a second pressure of gas provided to the blending chamber gas inlet. The first pressure of gas received from the pressurized gas source is greater than the urea injection pressure and the second pressure of gas provided to the blending chamber gas inlet is less than the urea injection pressure.

The plurality of chamber connectors may define a substantially longitudinally straight passage extending through the plurality of dissolving chambers. Also provided is a related method of dissolving a gas in a liquid.

An apparatus comprising: a vessel component comprising a flow-through interior chamber having an interior sidewall and an exterior sidewall; at least two inlets for introducing chemical components into the flow-through interior chamber; at least one outlet for removing product from the flow-through interior chamber; and an off center rotation component which is operatively connected to the vessel component. During operation of the apparatus, the off center rotation component generates vortical movement of at least two chemical components through the flow-through interior chamber of the vessel, and converts at least a portion of the at least two chemical components to at least one reaction product or product mixture. A method of using the apparatus to produce reaction products or product mixtures. The apparatus and method are useful for producing specialty chemicals such as fragrance and flavor compounds, insect pheromones, petrochemicals, pharmaceutical compounds, agrichemical compounds, and the like.

Disclosed herein is an assembly for selectively aerating a liquid including a base member a reservoir adapted to receive the liquid. The assembly also includes a support member non-rotatably coupled to the base member and a diverter member coupled to the support member and rotatable between a first diverter position and a second diverter position. The diverter member has at least one primary aperture and at least one secondary aperture. The assembly additionally includes an aerator member non-rotatably secured to the diverter member, the aerator member having an aeration aperture. In the first diverter position, a portion of the liquid in the reservoir flows through the primary aperture. In the second diverter position, a portion of the liquid in the reservoir flows through the secondary aperture, and though the aeration aperture.

A mixer for a continuous flow reactor and methods for forming the mixer and the operation thereof. The mixer allows for segmentation of a primary reactant flow through a plurality of ports into many smaller flows that are injected as jets into a secondary reactant flow in channels of the mixer. The channel has a constant width dimension to enhance even flow distribution and local turbulence of the primary and secondary reactant flows. The constant width dimension of the channel and the size and number of the ports of the mixer can be configured to ensure the primary reactant flow injected into the channel directly impinges on a surface of the channel that is opposite the injection point at normal operating conditions.

A microfluidic chip is disclosed. According to an embodiment, a microfluidic chip including an inlet part in which a first inlet is provided into which a first fluid is injected; a middle part in which a first flow path is provided in which the first fluid can flow, wherein on the first flow path, a raw material storage part may be provided for storing a mixed raw material which can be mixed with the first fluid.

The invention pertains to a spray/gas mixer, comprising: a main body having a circumferential wall with a first longitudinal axis (A) and extending from a first end to a second end, the first end defining an inlet opening, the second end defining an outlet opening; a divider baffle inside the interior; a swirl duct within the interior along a second longitudinal axis (B), having one end adjacent to the wall and a second end extending to the divider baffle; an injector orifice at the first end of the swirl duct; a swirl promoting means; and a restrictor arrangement. The swirl promoting means is arranged between the divider baffle and the restrictor arrangement, such that gas passing through the swirl promoting means is swirled around the first longitudinal axis (A) before passing through the restrictor. The restrictor arrangement is disposed between the swirl promoting means and the second end, forcing gas reaching it from an upstream side away from a peripheral region of the interior towards a center axis of the main body.

Present application relates to a mixing device (10) for mixing a first gas with a second gas, the second gas being corrosive to the mixing device. The mixing device comprises a first gas guiding part (12) having a first gas guiding inlet part (14) and a first gas guiding outlet part (16), a second gas guiding part (18) having a second gas guiding inlet part (20) and a second gas guiding outlet part (22), the second gas guiding outlet part arranged in the first gas guiding part so that the first gas and the second gas are mixed and a guide vane configured to establish a swirling motion in the first gas. Further disclosed is a related method.
