  • Patent number: 11097971
    Abstract: A composition for solid pellets and a process for removing water from particulate material slurries produced by horizontal drilling, vertical drilling and dredging of bodies of water are disclosed. The composition comprises a precipitating agent, a purification agent and, optionally, a binding agent. The process comprises the steps of 1) water removal accomplished by diffusing a chemical reagent into the particulate material source stream that results in separating out a clean water fraction and 2) reacting the sludge with a demulsifier and a superabsorbent polymer that locks onto the water in the remaining slurry thus turning the slurry into a solid crust. The crust is ground into a particulate form and disposed in a landfill. The combined effect of the treatments is the thickening of the particulate material slurry from about 10% solids to about 25% solids. The removed water may be used for further drilling and drinking.

  • Patent number: 10854890
    Abstract: The present invention relates to a cross-linked porous membrane from hydrolysis of ester-containing side chain and a preparation method thereof. Firstly, membrane material is obtained through copolymerization of four monomers including butyl methacrylate, styrene, sodium sulfonated styrene and vinylbenzyl chloride. In membrane formation, a small amount of lithium chloride micromolecule porogen is added and cross-linked by using tetramethyl hexamethylene diamine to prepare a nanoscale dense membrane through hydrolysis under the alkaline condition. Through the characteristic of hydrolysis of a butyl ester side chain in the polymer under the alkaline condition, the space originally occupied by the butyl ester in the hydrolyzed membrane is vacated; and after hydrolysis, with the appearance of carboxylic acid ionic conduction groups, a large quantity of ester bonds is hydrolyzed, so that the patency of ion transfer channels in the membrane is enhanced. Thus, ionic conductivity of the membrane is greatly enhanced.

  • Patent number: 8968692
    Abstract: The present invention relates to a method for removing sulfur from a gaseous or liquid mixture. This method involves contacting the gaseous or liquid mixture with an iron-enriched matrix under conditions effective to remove sulfur from the mixture through adsorption of the sulfur to the matrix. The iron-enriched matrix used in this method is a lignocellulosic material that is enriched with iron. The present invention also relates to a system, composition, and plant fertilizer that contain the iron-enriched matrix. Methods of making the composition and preparing a plant fertilizer are also disclosed.

  • Patent number: 8961821
    Abstract: A process of treating a gas stream containing mercury and acid gas pollutants is disclosed. The process includes applying a sorbent composition into a gas stream in order to adsorb mercury containing compounds and acid gas pollutants. The sorbent composition includes a compound having the formula (SiO2)x(OH)yMzSaF.B. The combination of basic inorganic solids for the adsorption of acid gases, and metal sulfide-doped silica for the adsorption of mercury provides dual sorbent functionality, along with additional benefits for each individual sorbent: silica for moisture retention on the surface of the basic inorganic particle and adsorption of acid gas, which will improve metal sulfide performance at higher operating temperatures. The use of a hygroscopic solid effectively dries the metal sulfide-doped silica slurry without the use of filtration of drying equipment, providing significant economic benefit for the manufacture of metal sulfide-doped silica material.

  • Patent number: 8945280
    Abstract: An amine solvent solution that is useful in absorbing acid gases from a liquid or gas feed stream may have an amine additive added thereto. Additionally or alternatively, the amine additive may be added to a liquid or gas feed stream. The addition of the amine additive decreases the presence of amine-derived contaminants and/or degradation of amine in the amine solvent solution. As such, the amine solvent solution is available for effective reuse in treating the liquid or gas feed stream and there may be a decrease in the corrosion within an amine treating system.

  • Publication number: 20150024511
    Abstract: A solid phase for use in separation has been modified using an aqueous phase adsorption of a headgroup-modified lipid to generate analyte specific surfaces for use as a stationary phase in separations such as high performance liquid chromatography (HPLC) or solid phase extraction (SPE). The aliphatic moiety of the lipid adsorbs strongly to a hydrophobic solid surface, with the hydrophilic and active headgroups orienting themselves toward the more polar mobile phase, thus allowing for interactions with the desired solutes. The surface modification approach is generally applicable to a diversity of selective immobilization applications such as protein immobilization clinical diagnostics and preparative scale HPLC as demonstrated on capillary-channeled fibers, though the general methodology could be implemented on any hydrophobic solid support material.
