Abstract: In some embodiments a process includes introducing an aqueous solution to a first hydrocarbon solvent to form an emulsion, wherein the aqueous solution comprises an oxidizing agent containing solution and a surfactant containing solution. The process further includes introducing a cement to the emulsion to form a first mixture within a reactor, wherein the cement comprises a butyl rubber elastomer and a second hydrocarbon solvent that is the same as or different than the first hydrocarbon solvent. The process further includes introducing a halogen source to the first mixture contained within the reactor to form a second mixture comprising a halobutyl rubber elastomer. The process further includes introducing a neutralizing agent with the second mixture to form a third mixture. The process further includes isolating the halobutyl rubber elastomer from the third mixture.

Abstract: Systems and methods are provided for low temperature separation of sweep gas from desorbed components. This can allow for performance of sorption/desorption cycles at reduced temperatures and/or pressures. Methanol is an example of a sweep gas that can be used for desorption at reduced temperatures. CO2 is an example of a component that can be sorbed and desorbed using a sorption/desorption cycle with reduced temperatures and/or pressures.

Abstract: Advantaged separation of xylene isomers may be realized by separating o-xylene and other components, such as styrene, from an aromatic hydrocarbon mixture comprising m-xylene and p-xylene. Separation of xylene isomers may comprise: providing an aromatic hydrocarbon mixture comprising at least o-xylene, m-xylene, and p-xylene; separating the aromatic hydrocarbon mixture into a first stream enriched in o-xylene and lean in m-xylene and p-xylene relative to the aromatic hydrocarbon mixture, and a second stream enriched in m-xylene and p-xylene and lean in o-xylene relative to the aromatic hydrocarbon mixture; and separating the second stream into a third stream enriched in p-xylene and lean in m-xylene relative to the second stream and a fourth stream comprising m-xylene.

Abstract: Thermal imaging may be used for obtaining measurements of a tribological testing apparatus including a contact temperature. For example a method of calculating a contact temperature may include: introducing a testing sample into a contact zone of a tribological testing apparatus; engaging a testing operation of the tribological testing apparatus; measuring a contact emission of a testing surface of the tribological testing apparatus with an infrared camera; and calculating a contact temperature of the testing sample in the contact zone from the contact emission; wherein the tribological testing apparatus has a carbon coating on the testing surface of the contact zone, wherein the carbon coating has a first infrared emissivity, wherein the testing sample has a second infrared emissivity, and wherein the first infrared emissivity is within +/−20% of the second infrared emissivity.

Abstract: Bicomponent carbon fibers may comprise an inner region that is at least partially surrounded by an outer sheath, each comprising at least one carbonized pitch. The inner region comprises 70 wt % or greater mesophase pitch that has been carbonized, and the outer sheath comprises up to 70 wt % mesophase pitch that has been carbonized. An amount of mesophase pitch in the outer sheath is lower than in the inner region. The bicomponent carbon fibers may be formed by extrusion of first and second pitch compositions having the requisite amounts of mesophase pitch, followed by carbonization.

Abstract: A method of full wavefield inversion using simultaneous-source, ocean bottom sensor (OBS) data, including: obtaining, with a computer, simultaneous-source OBS data recorded by receivers in a seismic acquisition; generating, with a computer, synthetic OBS seismic data from a model based on reciprocity; blending, with a computer, the synthetic OBS seismic data; differencing, with a computer, the simultaneous-source OBS data recorded by receivers and the synthetic data to form a pseudo-deblended residual; updating the model based on the pseudo-deblended residual; and prospecting for hydrocarbons at a location derived from the updated model.

Abstract: The present disclosure relates to methods and systems for treating a fluid produced from a biorefinery to remove contaminants, such as metals and sulfur therefrom. Biomass is pyrolysed and activated to form activated carbon used to remove such contaminants. The fluid produced from the biorefinery may be one or more of a biofuel, a biogas, and wastewater.

Abstract: A method for monitor-centric interpretation of offset pressure monitoring measurements includes simultaneously hydraulic fracturing treatment stages corresponding to treatment wells, measuring corresponding pressure data via pressure gauge(s) at monitor well(s), detecting pressure responses corresponding to fracture hits within the pressure data, and determining a reasonable velocity window for when a fracture originating from each treatment stage is likely to affect the pressure data. The method includes detecting treatment stage(s) that are likely to be the origin of each fracture hit based on the reasonable velocity window and, for each fracture hit that only has one likely originating treatment stage, assigning the detected fracture hit to such treatment stage. The method includes determining observation property data corresponding to the treatment stages that have been assigned to the fracture hits and iteratively assigning, based on such data, each unassigned fracture hit to one of the corresponding likely originating treatment stages.

Abstract: A method for producing a deposit resistant fluid includes combining a base stock and one or more additives to form a blended fluid configured to resist forming deposits in an oxidizing environment. The base stock has a viscosity index of at least 80, and either a kinematic viscosity at 40° C. of at least 320 cSt or a kinematic viscosity at 100° C. of at least 14 cSt. The base stock includes greater than or equal to about 90 wt % saturates, less than or equal to about 10 wt % aromatics, and a sum of terminal/pendant propyl groups and terminal/pendant ethyl groups of at least 1.7 per 100 carbon atoms.
