A fuel additive cartridge for use with a dimethyl-ether fuel system of a vehicle includes a reservoir for storing and dispensing a liquid fuel additive into a flow of fuel in a fill conduit during refueling. The cartridge also includes a dispenser actuated by the fuel flow to selectively dispense the liquid fuel additive from the reservoir. The fuel additive cartridge is intended to attach to a dimethyl-ether fuel system at a location between a fueling inlet connector and a storage tank to facilitate a metered mixing of liquid fuel additive from the cartridge and dimethyl-ether during the re-fueling of the storage tank.

A sequential mixer for mixing a heated hydrocarbon stream and a supercritical fluid to produce an intimately mixed stream upstream of a supercritical reactor. The sequential mixer comprising a body having a body length and a body diameter; a hydrocarbon inlet physically connected to the body, having an inlet diameter, the heated hydrocarbon stream is introduced through the hydrocarbon inlet; a mixed stream outlet physically connected to the body and fluidly connected to the supercritical reactor, having an outlet diameter; a traversing axis extending through the center of the body from the hydrocarbon inlet to the mixed stream outlet; and a plurality of fluid ports physically connected to the body, the plurality of fluid ports are arranged in a port alignment arrayed along the traversing axis, each fluid port has a port diameter and a port angle, the supercritical fluid is injected through the plurality of fluid ports.

A chemical liquid application apparatus according to one embodiment includes: a processing unit which applies a chemical liquid to a substrate; and a viscosity adjustment unit including a viscosity adjustment bottle which mixes a chemical liquid and a diluent. The viscosity adjustment bottle includes a first introduction port into which the chemical liquid is introduced, a second introduction port into which the diluent diluting the chemical liquid is introduced, a porous body which is connected to the first and second introduction ports and includes a plurality of holes through which the chemical liquid and the diluent introduced from the first and second introduction ports flow, and a discharge port which is connected to the porous body and from which the mixture of the chemical liquid and the diluent is discharged.

A chemical mixture dispensing assembly for automatically filling a fluid containment with a predetermined ratio of chemicals and water includes a housing that is mountable on a support surface such that the housing is positioned proximate a fluid containment. The housing is fluid coupled to a water source, a first chemical source and a second chemical source. A mixing unit is positioned in the housing and the mixing unit mixes a predetermined volume of fluid from the first chemical source and the second chemical source with a predetermined volume of water from the water source to produce a fluid mixture. The mixing unit dispenses a predetermined volume of the fluid mixture from the mixture outlet to fill the fluid containment with the fluid mixture.

A thickener for dewatering fluids having a vessel with a central well extending proximate a top portion of the vessel to a lower cone-shaped portion, a hindered settling zone, and a compressible sediment layer zone within the lower cone-shaped portion. Eductors housed in inlet wells have an inlet nozzle and a mixing tube to receive slurry to be treated and clear fluid to be mixed with the slurry. The fluid from the eductors is directed in counter circular paths via circular chambers situated proximate the inlet wells, such that fluid flowing in each direction collides and forms turbulence within the central well. Resultant fluid is directed into a lamella-type separator circumferentially located about a portion of the central well, having layered fluid paths directed radially outwards from said center longitudinal axis and upwards towards said vessel top portion through a conical, inclined fluid path, plate structure. The eductors are adjustable with a movable iris for limiting the amount of clear fluid exiting the eductor.

A system for mixing a sample with a combined buffer includes a sampler body, the sampler body including a first reservoir and a second reservoir. The system further includes a first separator forming a first enclosure with the sampler body for the first reservoir. The system further includes a second separator forming a second enclosure with the sampler body for the first reservoir. The system further includes a third separator, in conjunction with the second separator, forming a third enclosure and a fourth enclosure, respectively, both in conjunction with the sampler body, for the second reservoir.

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.
