Abstract: While some triazines have low reactivity, a method and composition is described for improving their reactivity. The H2S scavenging composition and method utilizes a tertiary amine to catalyze the scavengers with slower kinetics to achieve improved results over traditional systems with the scavenger alone. A hydrogen sulfide scavenging composition comprises: a tertiary amine as a catalyst in at least one of (i) a triazine scavenger selected from the group consisting of: methyl amine, C2-C5 alkyl amine, dimethylaminopropylamine, isopropanolamine, aniline, cyclohexylamine, isobutanolamine and methoxypropylamine triazines/bisoxazolidines; or (ii) an aldehyde-based scavenger such as glyoxal.

Abstract: A carrier fluid or fluidizer for use in fuel performance additives or fuels including such additives is described herein. The novel carrier fluids include a unique blend of alkoxylated alcohols or polyols providing unexpected performance improvements to fuel performance additives and fuels incorporating the additives. The carrier fluids, when combined with at least a detergent, provide desired valve stick performance and unexpectedly improve the intake valve deposit performance at the same time.

Abstract: An absorbent for selective removal of hydrogen sulfide from a fluid stream comprises an aqueous solution of a) a tertiary amine, b) a sterically hindered secondary amine of the general formula (I) in which R1 and R2 are each independently selected from C1-4-alkyl and C1-4-hydroxyalkyl; R3, R4, R5 and R6 are each independently selected from hydrogen, C1-4-alkyl and C1-4-hydroxyalkyl, with the proviso that at least one R4 and/or R5 radical on the carbon atom bonded directly to the nitrogen atom is C1-4-alkyl or C1-4-hydroxyalkyl when R3 is hydrogen; x and y are integers from 2 to 4 and z is an integer from 1 to 4; where the molar ratio of b) to a) is in the range from 0.05 to 1.0, and c) an acid in an amount, calculated as neutralization equivalent relative to the protonatable nitrogen atoms in a) and b), of 0.05 to 15.0%. One preferred amine of the formula I is 2-(2-tert-butylaminoethoxy)ethanol. The absorbent allows a defined H2S selectivity to be set at pressures of the kind typical in natural gas processing.
