A multi-blender system for blending liquid and solid particulates together to prepare a fracturing fluid, the blender system can include a plurality of independently operable blender units each having components that can operate with either blender unit. Each component may be a modular blender component mounted to respective independent frames. The independent frames are configured to be independently removable, replaceable and movable to multiple positions in the blender system. In some aspects the multi-blender system can operate at different sand concentrations, instantaneously adjust flow rate to one or more of the components in either blender unit, provide control redundancy, and may continue to operate despite a failure of one of the major components.

A device for preparing a gelatin-based product may include a mix tank, a mix pod that is fluidly coupled to the mix tank via a pod spike, and a hot water tank, where the hot water tank is coupled to the mix pod via the pod spike. In at least one example, the pod spike may include an outer tube and an inner tube. In one or more examples, the pod spike of the device may include a hub, where a first end of the outer tube is coupled to the hub. Further, in some examples, a first end of the inner tube may also be coupled to the hub.

The contacting device for countercurrent contacting of fluid streams and having a first pair of intersecting grids of spaced-apart and parallel deflector blades and a second pair of intersecting grids of spaced-apart and parallel deflector blades. The deflector blades in each one of the grids are interleaved with the deflector blades in the paired intersecting grid and may have uncut side portions that join them together along a transverse strip where the deflector blades cross each other or adjacent opposed ends of the deflector blades and cut side portions that extend from the uncut side portions to the ends of the deflector blades. At least some of the deflector blades have directional tabs and associated openings to allow portions of the fluid streams to pass through the deflector blades to facilitate mixing of the fluid streams.

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.

Provided is a slurry manufacturing method in which a decrease in slurry quality, an increase in running cost, and a decrease in maintainability are suppressed. A slurry manufacturing device includes: a mixing device (suction pump mechanism portion) that mixes a liquid and a powder to manufacture a slurry; a powder supply device that supplies the powder to the mixing device; and a powder dry box, in which an opening portion of the powder supply device is accommodated in the powder dry box.

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.

The present invention discloses a method for proppant suspension and suspension parameter optimization based on bubble bridge effect, comprising: select a proppant and hydrophobically modify its surface to obtain a hydrophobically surface-modified proppant; prepare a bubbly fracturing base fluid; make the first optimization of the base fluids according to the average radius of the proppant and the average radius of the bubbles of the base fluids; optimally select the base fluids selected for the second time according to the interaction energy between the proppant particle and the bubble after the hydrophobically surface-modified proppant mixed with the base fluid; the basic parameters of the bubbly fracturing base fluid selected at the third time were used for the perfect selection for proppant suspension. The present invention establishes a procedure on experimental evaluation and parameter calculation optimization by suspending fracturing proppant with the bubble bridge effect on the hydrophobic surface.

A system and method for mud mixing using a container to hold a joint compound and the water. The container having a lid to keep the container shut and preventing the liquids from escaping wherein the container may then be shaken by the user to mix the joint compound with the water. The user then may remove lid and pull on a rod and plate connected to one another at the bottom of holding container. Rod and plate act as a pressure seal, whereby when the rod is pulled all of the mud may be removed from the container and placed into a pan for use.
