  • Patent number: 10731087
    Abstract: The present invention generally relates to a method for separating solids from liquid in a slurry comprising solids and a liquid (e.g., an aqueous solution). More specifically, the method comprises contacting an effective amount of a high molecular weight polymeric flocculant with the slurry in a tanker truck or as the slurry is flowing to the truck, allowing the solids to settle during a settling time whereby the solids settle to the bottom of the tanker truck, and the liquid is removed from the tanker truck at a level above the settled solids. The high molecular weight polymeric flocculant can comprise repeat units derived from a cationic monomer, an anionic monomer, a nonionic monomer, or a combination thereof.

  • Patent number: 9932255
    Abstract: The present invention generally relates to methods for removing an organic deposit or for inhibiting deposition of deposit-forming comprising contacting a cleaning composition or an anti-coking composition with a surface. The surface can have an organic deposit or be susceptible to forming an organic deposit and the surface can be in contact with a liquid containing organics. The liquid can be produced from a thermal recovery system, and the surface can be an internal surface of a piece of steam-generating or vapor-generating equipment.

  • Patent number: 9477238
    Abstract: This disclosure relates to systems, methods, and devices useful for monitoring and controlling water to be used, for example, in oil and natural gas production and hydraulic fracturing processes. An on-line unit for measuring, controlling, and optimizing the quality of water being used during the hydrocarbon production or hydraulic fracturing processes is also disclosed. Optimizing and controlling can include measuring one or more properties associated with the production water to be sure that the one or more properties are within an acceptable range and, if the one or more properties are not within the acceptable range for each respective property being measured, causing a change in flow of one or more water sources and/or one or more chemicals.

  • Publication number: 20140096971
    Abstract: A method of rapidly and essentially simultaneously creating and feeding a dispersion into a hydrocarbon process stream. This method allows for the effective use of chemical additives in a hydrocarbon process line that are highly unstable or that are very difficult to disperse. This is especially helpful in hydrofracturing operations as the very rapid flow rates require very fast dispersion formations. As a result the method allows greater fracking pressures which can be obtained with lower energy inputs and by using lessor amounts of chemical additives. As a result hydrocarbon extraction can be accomplished in a manner which is both more environmentally friendly as well as less expensive.

  • Patent number: 8106229
    Abstract: Organosilane-modified nanoparticles of silica, having a particle size of no more than 1 micron, in which the organosilane resides throughout the entire volume of the nanoparticles and not just at the surfaces of the nanoparticle. The nanoparticles may be in a colloidal solution. They may be prepared by hydrolyzing an alkali silicate under acidic conditions to obtain a silicic acid dispersion, followed by adding an organosilane having hydroxyl and/or hydrolyzable groups to the dispersion under acid conditions; and then raising the pH of the dispersion to at least eight to form the nanoparticles. They may be used in an effective paint primer/protective coating formulation.

  • Publication number: 20110151151
    Abstract: The present invention relates to a method for producing a print medium with enhanced whiteness and print quality. The method comprises applying a surface treatment composition of a general formula Cx(A)y(OH)z(SiO2)kSm where C is a cation, A is an anion, and S is a moiety that provides a surface charge selected from surface modifiers, stabilizing agents, and combinations thereof. A facet of the enhanced print quality includes, for example, improved inkjet printing characteristics selected from print density of a printed ink on the print medium, line growth of a printed ink on the print medium, bleed of a printed ink on the print medium, edge roughness of a printed ink on the print medium, mottle of a printed ink on the print medium, wicking of a printed ink on the print medium, show though of a printed ink through the print medium, and any combination of the foregoing.

  • Publication number: 20110046241
    Abstract: The present invention relates to a method for forming a calcium-based carrier particle consisting of the calcium-based material, an active, with or without a surface modification, a stabilizing agent, and the related composition. The calcium-based particle is illustrated by the general formula Cax(PO4)y(OH)zR and may also include a silica or silica oxide substituent. R is an active or actives such as an organic or inorganic molecule that includes markers, amines, thiols, epoxies, organosilicones, organosilanes, sulfates, and water soluble agents and, as needed, a surface modification, S, which may be either organic or inorganic. A stabilizing agent may be necessary to maintain dispersion of the particles in aqueous media. Examples of a surface modifying material and stabilizing agents are inorganic salts of aluminum and boron or organic materials such as organosilanes or low molecular weight polymers.
