Disclosed herein are beta-amino ester surfactant compounds and compositions useful in applications relating to inhibition of gas hydrate agglomerates in the production, transportation, storage, and separation of crude oil and natural gas. Also disclosed herein are methods of using the compounds and compositions as gas hydrate inhibitors, particularly in applications relating to the production, transportation, storage, and separation of crude oil and natural gas.

The present invention concerns a suspension comprising carbonaceous material particles, an alkoxylated phenol surfactant, and an aqueous liquid phase providing a high stability to the suspensions over time. The invention also concerns a process for the production of said suspensions and methods for generating power comprising combustion of said suspensions, notably with appropriate devices.

An anti-static fuel additive composition and method for using the composition to reduce or prevent buildup of electrostatic charge is described. The anti-static fuel additive composition comprises a polysulfone and a copolymer derived from reaction of an alkanolamine and a hydrocarbyl-substituted 4-membered to 7-memebered ring anhydride; for example, a hydrocarbyl-substituted succinic anhydride, a hydrocarbyl-substituted maleic anhydride, a hydrocarbyl-substituted phthalic anhydride, or a combination thereof.

Biological source oils, including, but not limited to, algae oil, stabilize the presence of asphaltenes in petroleum feedstocks, such as crude oil, to help avoid or prevent fouling and/or corrosion in the production, transferring and processing of the petroleum feedstocks. Chemical additives such as phenol-based resins, and reaction products or combinations of long chain alpha-olefins and/or small chain aldehydes and/or long chain alkyl phenate sulfides and/or metal oxide-based colloidal hydrocarbon-based nanodispersions, may also stabilize the presence of asphaltenes in petroleum feedstocks. By stabilizing is meant keeping the asphaltenes in solution in the petroleum feedstocks.

Additive composition mixtures and methods for synergistically maintaining low surface voltages of distillate fuels that include a synergistic conductivity improver additive composition for a distillate fuel. The additive composition includes: A) a mixture of (i) alkenyl polysulfone polymer, (ii) C16-C24 substituted maleic/polyamine copolymer, (iii) sulfonic acid, and (iv) aromatic solvent; and B) a mixture of (i) alkenyl polysulfone polymer, (v) polymeric reaction product of a C8-C18 aliphatic amine or diamine with epichlorohydrin; (iii) sulfonic acid, (iv) aromatic solvent; and optionally (vi) a quaternary ammonium compound. The additive composition contains from 30 to 60 wt. % component (A) and from 30 to 60 wt. % component (B) based on a total weight of the additive composition.

A synergistic mixture comprising from 1 to 99.9% by weight of compounds having structural elements (I) ##STR00001##
in which the free valencies on the oxygen atom and on the nitrogen atom may be combined to form a five-, six- or seven-membered ring and the benzene ring may also bear substituents at one or more of the free positions, and from 0.1 to 99% by weight of sulfur-containing organic compounds with antioxidant action. This synergistic mixture is suitable as a stabilizer for stabilizing inanimate organic material, especially mineral oil products and fuels, against the action of light, oxygen and heat.
