摘要： A process for synthesizing a family of non-pillared metal oxide triple layered perovskite has been developed. The perovskite has a surface area of at least 30 m2/g and an empirical formula of AB2M3O10−x where A is a monovalent exchangeable cation such as cesium, B is a divalent or trivalent cation such as strontium or lanthanum and M is a +2, +3, +4 or a +5 valent metal such as niobium, titanium, aluminum or copper. The process involves forming a reaction mixture containing reactive sources of A, B and M at a pH greater than seven and a temperature and time sufficient to form the perovskite. A process for removing contaminants from effluent streams using the above perovskites is also disclosed.

摘要： A method and apparatus are provided for treating produced water to lower the total dissolved solids of the water for safe discharge to the environment. The produced water is passed through a weak acid cation resin in H+ form to remove cations in the produced water and then preferably through a decarbonator to remove formed CO2 and to provide a first discharge stream. The cation loaded resin is then regenerated using a dilute acid, preferably diluted with produced water, to regenerate the resin to the H+ form. The resultant acid regenerated waste stream is discharged to a reject deep well. The acid regenerated resin is then rinsed, preferably with produced water, to remove residual salts to form a residual salt containing rinse stream. This salt stream is passed into a reverse osmosis unit to form a high salt containing reject stream which is discharged to a waste deep well and a low salt containing product discharge stream which may be safely discharged to the environment.

The process includes the following steps, adding an ion-exchange resin to water containing a contaminant such as dissolved organic carbon, dispersing the resin in the contaminated water to enable adsorption of the dissolved organic carbon onto the resin, and separating the resin loaded with contaminant from the water. In a preferred embodiment the process employs a magnetic ion-exchange resin.

摘要： A method for treating metal-working fluid comprises the steps of: a) transferring the metal-working fluid into a heating vessel; b) heating the metal-working fluid in the heating vessel to maintain the fluid at an elevated temperature during a heating period; c) agitating and aerating the fluid during the heating period; d) transferring the fluid out of the heating vessel into a holding vessel after the heating period; and e) transferring the fluid out of the holding vessel. The fluid may pass through a particle filter before entering the heating vessel, where it may be heated to between about 145° F. and about 210° F. for at least about 30 minutes. During heating, heated ambient air may be drawn through air inlets and through the fluid to agitate and aerate the fluid, thereby ensuring uniform heating and extracting gaseous contaminants. Mist and gaseous contaminants are removed from the airflow prior to its release into the environment. After the heating period the treated metal-working fluid is transferred into a holding vessel and ultimately back to a metal-working machine for re-use. An apparatus for treating metal-working fluid comprises: a) a heating vessel; b) a heater for heating the fluid in the heating vessel to an elevated temperature to maintain the fluid at the elevated temperature during a heating period; c) an agitator for agitating the fluid during the heating period; d) an aerator for aerating the fluid during the heating period; e) a holding vessel; and f) a pump for transferring the metal-working fluid from the heating vessel into the holding vessel after the heating period.

摘要： Difluoromethane (R-32) is of current interest as a partial replacement for chlorodifluoromethane (R-22) refrigerant heretofore widely used in vapor compression refrigeration systems. R-32 has, however, proved to be more reactive than is desirable with the zeolite A adsorbent-desiccant compositions used in such systems to prevent corrosion and freeze-up problems. The potassium cation form of a zeolite A molecular sieve—with at least 60 percent of the sodium cations replaced with potassium ions, agglomerated with a clay binder, and pore-reduced to essentially exclude the adsorption of R-32 having essentially no reactivity with difluoromethane, and having a surface ratio of silicon to aluminum of less than about 1.7 mol/mol as determined by X-ray photoelectron spectroscopy—has been found to be an effective desiccant for refrigerants comprising difluoromethane.

摘要： A method and product for removing at MTBE molecules from a solution, such as a contaminated aquifer, includes exposing the solution to a plurality of molecularly imprinted polymer beads (MIPS) that have receptor sites on the surfaces thereof that include imprints that match the physical shape of at least a portion of an MTBE molecule. A quantity of the MTBE molecules align with and adhere to some of the receptor sites and, accordingly, they are removed from the solution producing a remediated solution. According to one embodiment, the MIPS are contained in an enclosure having a plurality of openings large enough to permit the solution to pass through and small enough so as to prevent the MIPS from passing through. According to a preferred embodiment the MIPS are applied (i.e., coated) to the inside surface of a conduit and the solution is forced or allowed to flow through the conduit thereby removing some of the MTBE molecules therefrom.
