Hydraulic fracture composition and method

A method for improving hydraulic fracturing creates coated proppants containing one or more chemical constituents bonded to a substrate and introduced into the fracturing fluid itself. The substrate that eventually acts as a proppant may be sand, ceramic, resin coated sand, and other materials. Typically, the materials that are coated as powders adhered to the substrate may include friction reducers, biosides, oxygen scavengers, clay stabilizers, scale inhibitors, gelling agents, or the like. By adhering solid materials to a substrate 12 by a binder 14, a single, solid, granular material may be maintained onsite, requiring reduced footprint, reduced mixing and may introduce almost instantaneously into a fracturing flow stream all the necessary chemical constituents, which will eventually become mixed. The result is reduced time, energy, manpower, equipment, and space at the sight, while reducing the environmental impact of transportation, spills, hydrocarbon use, and the like.

Method for increasing retention rate of calcium carbonate in paper-process reconstituted tobacco sheets

The invention relates to a method for increasing the retention rate of calcium carbonate in paper-process reconstituted tobacco sheets. The purpose of the invention is to solve the problems that: since the prior art directly adds calcium carbonate, the bonding force between the calcium carbonate and tobacco fibers is weak, as a result, loss is severe, the material utilization rate is low, the amount of waste water to be treated is large, and the treatment cost is high. The technical point is that: needed chemical constituents are extracted from tobacco material, residue is ground into pulp after extraction, and the concentration of the pulp is regulated between 3 percent and 25 percent; the solution of soluble carbonate accounting for 4 percent to 40 percent of the weight of dry fibers in the pulp is added into the pulp, and is fully stirred and uniformly mixed, and impregnation is then carried out for 20 to 150 minutes, so that the fibers of the pulp can be impregnated with the soluble carbonate; the solution of soluble calcium salt, the molar mass of which is approximately equal to the molar mass of the soluble carbonate, is added into the impregnated pulp, and is fully stirred and uniformly mixed, static reaction is then carried out for 30 to 180 minutes, and the reaction temperature is controlled at 5 DEG C to 50 DEG C; and after the static reaction, the pulp is made into reconstituted tobacco sheets by papermaking equipment.

Nebulizer with plasma source

A combination electrospray / microwave induced plasma (MIP) ionization source is used as the ionization source for a mass spectrometer. The electrospray can be operated in positive mode, negative mode, or it can be switched off. The microwave-induced plasma can also be switched on or off. This allows the instrument to be operated in multiple modes. With the electrospray off and the MIP on, the instrument will normally have its maximum elemental sensitivity. Mixed mode operation potentially allows the determination of additional information about the chemical constituents present in the analyte. In pure electrospray mode, it is possible to obtain molecular information and to analyze organic compounds.

Optical sensor and method for measuring concentration of a chemical constituent using its intrinsic optical absorbance

An improved optical sensor and method for measuring concentration of a chemical constituent where measurement interference from other chemical compounds is present in the solution is provided. More specifically, the invention relates to a system for measuring the amount of creatinine in effluent dialysate during, before, or following a kidney dialysis procedure and a method for using the same. Alternatively, the method may be used with blood and other body fluids or solutions that contact the patient. The system may use an enzyme or other chemical process to specifically remove or convert an analyte with an intrinsic optical absorbance. By measuring the absorbance before and after the chemical process the analyte can be measured with high accuracy and specificity. The method may be extended to multiple analyte measurements using cascaded chemical processes.

Cosmetic with fermented original rice milk, method for manufacturing cosmetic and application thereof

The invention discloses a cosmetic with fermented original rice milk, a method for manufacturing the cosmetic and application thereof. A process for preparing the fermented original rice milk includes steps of fermenting and cultivating initial systems with bifidobacterium bifidum, dry rice flour and water to obtain the fermented original rice milk. A bacterium is the bifidobacterium bifidum. As proved by experiments, the cosmetic, the method and the application have the advantages that the fermented original rice milk does not contain optional chemical components, accordingly, the cosmetic can be directly used as a finished product of facial masks or essence or toner and is natural as compared with other products on current markets, and optional negative effects on the skins of users can be prevented; small components can be acquired by the aid of the method as compared with common extraction methods, and accordingly the cosmetic can be easily sufficiently absorbed by the skins of the users.

Arc plasma jet and method of use for chemical scrubbing system

A chemical scrubbing apparatus includes a first chamber configured to generate a non-rotating arc therein, a second chamber in communication with the first chamber, and a gas injector injecting a first gas into said arc to generate a plasma jet. The apparatus further includes a first inlet for injecting a substance into the first chamber, a mixing region, the substance mixing with the plasma jet in the mixing region whereby the plasma jet disassociates the chemical constituents of the substance in the mixing region, and a second inlet for directing a second gas and / or water into the first chamber at the mixing region. The mixing region directs the chemical constituents into the second chamber, and the second chamber is adapted to quench the chemical constituents to reduce the reactivity of the chemical constituents to thereby maintain their disassociation.
