摘要： The use of a composition that includes a metal salt and an oil soluble amine formaldehyde reaction product scavenges H
2 S that is present in aqueous fluids (e.g. produced water liquid streams), natural gas and in oil and mixtures thereof (e.g. mixed production streams that contain all three phases) better than either component when used alone. The resulting scavenger combination significantly increases the reaction rate and the overall scavenging efficiency, i.e. capacity over each component when used alone, in the same total amount. Non-limiting examples of the metal salt include zinc or iron carboxylates, and a non-limiting example of an oil soluble amine formaldehyde reaction product is the reaction product of dibutylamine with formaldehyde.

摘要： Trace amount levels of heavy metals such as mercury in crude oil are reduced by contacting the crude oil with a sufficient amount of a reducing agent to convert at least a portion of the non-volatile mercury into a volatile form of mercury, which can be subsequently removed by any of stripping, scrubbing, adsorption, and combinations thereof. In one embodiment, at least 50% of the mercury is removed. In another embodiment, the removal rate is at least 99%. In one embodiment, the reducing agent is selected from sulfur compounds containing at least one sulfur atom having an oxidation state less than +6; ferrous compounds; stannous compounds; oxalates; cuprous compounds; organic acids which decompose to form CO
2 and / or H
2 upon heating; hydroxylamine compounds; hydrazine compounds; sodium borohydride; diisobutylaluminium hydride; thiourea; transition metal halides; and mixtures thereof.

摘要： The present invention provides selective extraction of sulfoxides, or sulfoxides in combination with sulfones, from hydrocarbon mixtures containing these compounds. A significant advantage of the invention is that oxidation products resulting from oxidative desulfurization of hydrocarbon feedstocks are selectively extracted with minimum co-extraction of non-oxidized products such as valuable hydrocarbon fuel components.

摘要： Polymeric naphthenate inhibitors may be delivered into production fluids for contact with mixtures of oil and water, such as in a hydrocarbon producing formation, production equipment, or processing systems. These polymeric naphthenate inhibitors exhibit surface-active properties that cause the inhibitors to self-associate at oil- water interfaces. The relatively large surface area makes these polymers more persistent and more efficient in terms of required concentration. The presence of these polymers on the oil/water interface inhibits interactions between organic acids in the oil with cations or cation complexes in water. These compounds also inhibit aggregation of organic acid carboxylate salts that form when pH and pressure conditions are amenable to organic acid ionization. Preferred inhibitors do not form emulsions due to the formation of unstable mixed interface structures that result in coalescence of dispersed droplets. Naphthenate inhibitor compound dosages of less than 100 ppm can effectively inhibit naphthenate salts or other organic acid salts that can form precipitates or emulsions during crude oil production or processing.

摘要： The use of neutral aqueous solutions of glyoxal (pH approximately 6 to 8.5) scavenges H
2 S that is present in natural gas and in oil better than glyoxal alone or base alone. The resulting scavenger combination significantly increases the reaction rate and the overall scavenging efficiency, i.e. capacity over glyoxal used alone. A buffer may be optionally used. In another embodiment, the combination of non-nitrogen-containing surfactants and glyoxal results in a significant increase in the reaction rate and the overall scavenging efficiency, i.e. capacity as compared to glyoxal used alone.

摘要： Low molecular weight gelators, methods of making such gelators, organogels comprising such gelators and systems and methods of using such gelators for the containment and/or remediation of a release and/or spill of a crude oil, a petroleum product and/or a chemical is described. In exemplary systems and methods, gels and/or emulsions formed from the combination and/or contact of such gelators and at least one of a crude oil, a petroleum product and a chemical from a release and/or spill into the environment can be used to recover these oils or chemicals while allowing the gelators to be recovered and reused to clean up or contain additional crude oil, petroleum products or chemicals.

摘要： Multi-valent metals, such as iron, may be removed from crude oil by introducing at least one metal removal chemical to the crude oil before, during or after the crude oil is charged to a settling tank. After mixing the metal removal chemical with the crude oil, the crude oil is kept still or held quiescent for an effective period of time to allow the metal species to settle to the bottom of the tank. Oil having reduced metal content may be removed from the top of the tank and/or metal-rich oil may be drained from the bottom of the tank or both. The crude oil having reduced metal content will cause fewer problems downstream in the refinery.
