This disclosure provides a pre-mixed lost circulation treatment that can be pre-mixed ahead of time at a plant and delivered to a drilling site in one or more transport containers because the pre-mixture having a shelf life of at least one month and possibly longer. Because the components of the lost circulation treatment are mixed at a controlled mix site, the consistency of the lost circulation treatment is improved and can be better maintained from one lost circulation treatment to another. Further, one or more of the components of the pre-mixed treatment can be placed in a portable tote container that can be quickly and easily transported to the drilling site upon demand, or the tote can be delivered to the drilling site before a lost circulation zone is actually encountered.

An atomization generator and a special high-pressure atomization generation device for increasing oil and gas field recovery are provided. The special high-pressure atomization generation device for increasing oil and gas field recovery includes an agent pot assembly, a gear pump, a metering pump, an atomization generator and pipelines. The gear pump is connected with the agent pot assembly through an agent pot liquid inlet pipe. The metering pump is arranged between the agent pot assembly and the atomization generator which are connected through the low-pressure manifold pipeline and the high-pressure liquid inlet pipeline. The high-pressure liquid inlet pipeline is connected with the liquid inlet pipe. The liquid inlet pipes are connected with the metering pump. The gas inlet pipe is connected with the high-pressure gas source through the high-pressure gas inlet pipe. The gas inlet cap is provided with a gas inlet pipe.

A dispensing machine for dispensing fluid products comprising a dispensing zone (15) in which elongated support means (12) are disposed, configured to support a plurality of removable containing units (11) of the fluid products in a stationary manner along a longitudinal axis (X) is disclosed. The dispensing zone (15) further includes translation means (20) configured to allow moving a receptacle (18) positioned on a metering unit and disposed on the translation means (20) substantially parallel to the longitudinal direction (X) to delivery positions substantially vertically below said containing units (11) and measurement means (16) configured to meter a quantity of fluid product that is delivered from a containing unit (11) to the receptacle (18) in a delivery position corresponding to the respective containing unit. Also disclosed is the use of such dispensing machine for preparing customized formulations of fluid products as well as a method for preparing user-defined target formulation from a plurality of dispensable fluid products.

Provided are a method for supplying water of specified concentration, including: a step of adding at least two liquids, a conductive first liquid and a non-conductive second liquid, to ultrapure water to produce water of specified concentration containing a first liquid-component and a second liquid-component at specified concentrations, in which a mixed solution in which the first liquid and the second liquid are mixed at a specified mixing ratio in advance is prepared; and the mixed solution is added to the ultrapure water so that a conductivity or specific resistance of the ultrapure water after the addition satisfies a specified value, and an apparatus therefor.

A device and method for in-line homogenizing a non-uniform feed stream is described herein, which includes a plug flow reactor (PFR), a bypass line, and a pump in a closed-circuit flow path that allows for rapid homogenization of the non-uniform feed stream.

Various methods and systems are provided for mixing and dispensing viscous materials for the creation of additive structures. As one example, during a mixing and dispensing operation of a multi-dimensional printing apparatus, one or more liquids may flow into a mixing chamber via one or more material inlets arranged in a wall of the mixing chamber below a high pressure bearing of a mixing rod positioned within the mixing chamber; and movement of a mixing rod positioned within the mixing chamber is adjusted based on an operating condition of the printing apparatus.

Methods and apparatuses for producing a substrate are described. A method and apparatus for introducing a component into a fluid supply is also presented. A method can include providing a first fluid supply. The fluid supply can be configured as a foam in some embodiments. The method can also include providing a component feed system and a supply of the component. The method can include introducing the component to a fluid supply in an eductor in some aspects. A resultant slurry including a fluid supply and the component can be transferred through a headbox. The resultant slurry can be dewatered to provide a substrate including the component.

Mobile systems for mixing and dispensing. The systems include a vehicle, a dispenser, a means for transferring a primary fluid to the dispenser from a primary fluid source, and one or more vessels of a secondary fluid that are fluidly connected to the dispenser. The dispenser includes an assembly of fluid distribution components that define a fluid channel that enables the primary fluid to flow through the dispenser. Incorporated into the fluid channel is an aspirator component that enables the dispenser to aspirate a secondary fluid into the fluid channel when the primary fluid is flowing through it, thereby yielding an operative fluid. Disclosed are embodiments of the system where the means for transferring a primary fluid is either a stand-alone pump or a truck mount. Also disclosed are embodiments of the system where the primary fluid source is a portable vessel located within the interior of the vehicle.

The invention relates to the field of mixing plants, in particular, to devices for mixing a powder reagent with a flow of a liquid medium. The specified technical result is produced due to the development of an apparatus for injection of a powder reagent into the flow of a petroleum product, which comprises: a cylindrical mixing chamber, an inlet for feeding a powder reagent, an outlet to remove the powder reagent mixed with the petroleum product; a powder reagent introducer with an outlet connected to the inlet of the mixing chamber through a flow restriction device; a pump for feeding the mixture from the mixing chamber to the oil pipeline, in which the specified at least one inlet for feeding petroleum products are tangential, an inlet for feeding the reagent and the outlet to remove the mixture are axial.

A method for mixing liquids using an automated liquid handling system includes: aspirating liquid volumes of a first liquid and a second liquid from alternating ones of a first liquid supply and a second liquid supply into a mixing volume such that the aspirated liquid volumes form a liquid stack including a series of alternating, interfacing layers of the first and second liquids in the mixing volume; permitting the interfacing layers of the first and second liquids to mix with one another by diffusion in the mixing volume to form a mixture liquid; and dispensing the mixture liquid from the mixing volume.
