Abstract: A process to remove H2S from a stream comprising the steps of adding a glyoxal, a silica nanoparticle composition, and optionally a triazine to the stream. The stream is selected from the group consisting of Oil streams, Gas streams, CO2 point source purification streams and Geothermal Energy System streams.

Abstract: A method to reduce the deposition of solid sulfur (Ss(s)) in a natural gas producing well, is described wherein the inside of the pipes used in the well are coated with a coating comprising polar surface treated nanoparticles. The polar surface treated nanoparticles interact with the sulfur gas and interfere with the deposition of solid sulfur onto the surface of the pipe. The polar surface treated nanoparticles are selected from the group consisting of silica, alumina and silica-aluminate, metal sulfates and metal oxides.

Abstract: A method to reduce the deposition of solid sulfur (S8(s)) in a natural gas producing well is described where hydrophobic surface modified silica nanoparticles are added into the tubing string, and the hydrophobic surface modified silica nanoparticles interact with the gaseous sulfur (S8(g)) present in the gas resulting in the reduction of the deposition of solid sulfur (S8(s)), The hydrophobic surface modified silica nanoparticles are selected from the group that includes silica, alumina and silica-aluminate. The hydrophobic surface modified silica nanoparticles may be added to the tubing string either dry or mixed first into a carrier fluid, which carrier fluid may be a liquid or a gas.

Abstract: A system can include a filter assembly with a filter and a substance in the filter assembly, and at least one optical computing device having an integrated computational element which receives electromagnetic radiation from the substance. A method can include receiving electromagnetic radiation from a substance in a filter assembly, the electromagnetic radiation from the substance being received by at least one optical computing device having an integrated computational element, and the receiving being performed while a filter is positioned in the filter assembly. A detector may receive electromagnetic radiation from the integrated computational element and produce an output correlated to a characteristic of the substance. A mitigation technique may be selected, based on the detector output.

Abstract: Methods including preparing a treatment fluid comprising a bulk amount of anhydrous ammonia, wherein the anhydrous ammonia is present in an amount greater than about 10% by weight of a liquid portion of the treatment fluid, and wherein the anhydrous ammonia is in a phase selected from the group consisting of a liquid phase, a gaseous phase, supercritical phase, and any combination thereof; and introducing the treatment fluid into a subterranean formation.

Abstract: A memristor element is used to create a spectrally programmable optical computing device for use in, for example, a downhole environment. An electromagnetic field is applied across the memristor element in order to alter its spectral properties. In turn, the spectral properties of sample-interacted light optically interacting with the memristor element are also altered. This alteration in spectral properties allows the memristor to be “programmed” to achieve a variety of transmission/reflection/absorption functions.
