摘要： In accordance with this invention, a method is provided for decreasing hydrogen sulfide atmosphere, over sour heavy fuel oils to a predetermined acceptable level, which comprises treating such fuel oil with an effective amount of a choline base at a temperature above the decomposition temperature of the choline base. Surprisingly, this is effective to treat sour heavy fuel oils having atmospheric hydrogen sulfide content exceeding 5,000 ppm.

摘要： The present invention provides a method for inhibiting the evolution of H2S from sulfhydryl compounds in molten sulfur by using scavenging agents such as anhydrides and polymers thereof, conjugated ketones, carbonates, epoxides, monoesters and diesters of unsaturated dicarboxylic acids and polymers of these esters, and the like and mixtures thereof. In one embodiment, it is preferred that the scavenging agent is in liquid form at contact temperature with the molten sulfur. In another embodiment, the scavenging agent may be atomized into the vapor space over the molten sulfur to contact the sulfur with the agent.

摘要： It has been discovered that the polymerization of vinyl aromatic compounds, such as styrene, may be inhibited by the addition of a composition that contains a hindered hydroxylamine, and, optionally, a synergist together with the hindered hydroxylamine. In one embodiment of the invention, the hindered N,N-disubstituted hydroxylamine has the formula: [(R1R2R3)C]2N—OH where R1, R2, and R3 are independently selected from the group consisting of hydrogen, straight, branched or cyclic alkyl, aryl, aralkyl, and alkaryl moieties; where no more than two of R1, R2, and R3 on each C can be hydrogen at a time; where one or more of R1, R2, and R3 on one C may be joined to a R1, R2, and R3 on the other C to form a cyclic moiety selected from the group consisting of alkylene, and aralkylene moieties; where any two of the R1, R2, and R3 on any one C may be joined together to form a cycloalkyl; where any of the above definitions of R1, R2, and R3 may contain one or more heteroatoms selected from the group consisting of N, O and S; and where the total number of carbon atoms in the hindered N,N-disubstituted hydroxylamine ranges from 6 to 70. Optional synergists may include alkyl-substituted hydroxyarenes such as 2,5-di-tert-butylhydroquinone, and hydrogen transfer agents such as 1,2,3,4-tetrahydronaphthalene; and the like, and mixtures thereof.

摘要： Hydroxalkylaminium polysulfides are used to provide cold stability to ammonium polysulfide solutions. Hydroxyalkylaminium sulfides or polysulfides also are used to solubilize unwanted sulfur. Preferred aminium ions are monohydroxyalkylaminium ions, preferably monoethanolaminium ions. When added to an aqueous stream comprising free cyanide ions (including HCN), the polysulfide solution reduces corrosion of metal equipment contacted by the stream by converting the free cyanide ions into thiocyanate ions.
