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 method and composition is described for reducing the levels of hydrogen sulfide in a fluid such as a hydrocarbon stream. The method involves contacting the gas stream with a composition comprising a mixture of amines reacted with formaldehyde. The composition reduces the formation and deposition of solids commonly associated with spent triazine scavengers.

Abstract: A method of determining sulfur content in an aqueous fluid containing spent hydrogen sulfide scavenger from a scrubber or contactor tower is described as is a method of optimizing the hydrogen sulfide scavenger treatment rate in a scrubber or contactor tower. The method includes the steps of providing a sample of an aqueous fluid from the scrubbing tower where the aqueous fluid contains spent hydrogen sulfide scavenger; and using x-ray fluorescence to determine the amount of total sulfur in the sample. The method may also use the total sulfur content in the sample to determine the spent hydrogen sulfide scavenger in the sample and/or determine scavenger uptake. The method may also include the step of adjusting the amount of scavenger introduced into the aqueous fluid in the tower in response to the scavenger uptake, to optimize the scavenger treatment in the scrubber or contactor tower.
