摘要： A process for producing a silicon nitride compound is presented. A starting solution comprising fluorosilicic acid is provided. The starting solution is derived from a silicon, etching process wherein silicon is etched with a solution comprising hydrofluoric acid and where silicon powder has been removed. The starting solution is heated to yield a vapor solution comprising silicon tetrafluoride, hydrogen fluoride, and water. The hydrogen fluoride is separated from the vapor solution wherein a pure stream of silicon tetrafluoride and water vapor remain. The silicon tetrafluoride and water vapor are hydrolyzed to yield a concentrated fluorosilicic acid solution. The fluorosilicic acid is reacted with a base to yield a fluorosilicic salt. The fluorosilicic salt is heated to yield anhydrous silicon tetrafluoride. The anhydrous silicon tetrafluoride is reacted with a metal hydride to yield a monosilane. The monosilane is reacted to form a silicon compound and a silicon nitride compound. The silicon and the silicon nitride compounds are recovered. In an alternate embodiment, the hydrogen fluoride is recovered from the reaction process and reintroduced into the porous silicon etching process.

摘要： In accordance with the present invention, there are provided simplified systems and methods for deactivating, removing, or reducing the levels of reactive component(s) from vapor phase fluids prior to introduction thereof into fuel storage tanks. The simple apparatus described herein can be utilized to replace complex systems on the market. Simply stated, in one embodiment of the invention, the vapor phase fluid contemplated for introduction into the fuel storage tank is passed through a reaction zone (e.g., a catalytic bed) operated at appropriate temperatures to allow the reaction between free reactive components therein (e.g., oxygen and hydrogen or other fuel vapor), thereby deactivating reactive component(s) in the gas phase.

摘要： A ceramic bodied sensor having helical metallized electrodes for measuring the capacitance of an oil-water-gas or oil-water mixture flowing through a central bore of the sensor is disclosed. The sensor generally is a hollow cylinder with an inner ceramic layer which is very thin, a thicker outer ceramic layer which forms a strong structural unit, and a pair of isolated metallized electrodes which are generally approximately located between the inner and outer ceramic layers. The inner ceramic layer, outer ceramic layer and metallized electrodes form a dense monolithic ceramic tube. The electrode plates are preferably identical in size and shape and are isolated from one another electrically so that a condenser is formed by the separated plates. The inner ceramic layer is preferably very thin to minimize its capacitance value in comparison to the capacitance value of the water-oil-gas or oil-water mixture flowing through the central bore of the sensor. the sensor measures changes in the capacitance with changes in composition of the oil-water or oil-water-gas concentrations. Because the dielectric properties of oil and/or water and/or gas are considerably different, the relative composition of each fluid component can be mathematically modeled and thus measured.

摘要： In accordance with the present invention, there are provided systems and methods for contacting two or more fluids, useful, for example for purifying or infusing a fluid (by allowing efficient and/or uniform addition of components to or removal of components from the fluid). The components may be undesirable components to be removed from a fluid, or a desired component or components to be added to the fluid, for example, each of which is referred to herein as “component”. In this regard, the disclosed embodiments provide for the purification or infusion of a fluid by passing a liquid and a fluid through a contacting zone which facilitates intimate mixing of the liquid and the fluid. A differential of partial pressure, activity, fugacity or concentration of the components between the liquid and the fluid facilitates the transfer of the components between the liquid and the fluid in the intimately mixed liquid and fluid.
