Hydrogen sulfide is a common product in natural gas in many of the gas fields in Alberta, Canada. This gas is extremely toxic to human health and highly corrosive to pipelines and gas plant infrastructure. A common method for removal of H2S is the use of liquid hydrogen sulfide scavengers, most commonly, 1,3,5,-tris(2-hydroxyethyl)hexahydro-s-triazine (triazine, 1). Triazine reacts with 2 mol of H2S to produce 5-(2-hydroxyethyl)hexahydro-1,3,5-dithiazine (dithiazine, 3) and two moles of monoethanolamine (MEA, 4). The reaction proceeds through 3,5-bis(2-hydroxyethyl)hexahydro-1,3,5-thiadiazine (thiadiazine, 2) as an intermediate. “Overspent” scavenger, triazine that has been heavily consumed by H2S can lead to formation of solid dithiazine or amorphous dithiazine, leading to downstream plant problems. Qual. characterization of the reaction products would allow for plant operators to determine “how spent” their scavenger is and evaluate its potential scavenging capacity. NMR characterization remains uncommon industrially, despite triazine and its reaction products extensive characterization in the literature. Presented herein is the application low-field benchtop NMR for characterization of spent triazine, from both field and laboratory samples, using 1H and 13C NMR. By using low-field NMR, the authors were able to determine that even under aggressive field conditions, the starting triazine will not be fully used and that the scavenger stops effective removal of HS before both 1 or 2 are completely consumed. The experimental process involved the reaction of 2,2′,2”-(1,3,5-Triazinane-1,3,5-triyl)triethanol(cas: 4719-04-4).Related Products of 4719-04-4
