A novel way has been developed to utilize a proprietary catalyst incorporated into the liquid scavenging chem., called ENVIRO-TEK, to regenerate the spent chem. The regeneration is accomplished with air. This technol. innovation has dramatically reduced the cost of removing sulfur from several gas streams. The chem. of the process may be summarized as: REACTION 1 (contactor): triazine (1,3,5-tri(2-hydroxyethyl)hexahydro-s-triazine) + H2S ———-> dithiazine (5,6-dihydro-5-(2-hydroxyethyl)-4H-1,3,5-dithiazine) REACTION 2 (regeneration tank): dithiazine + O2 + catalyst —-> triazine + S0 + H2O. Single use triazine based liquid scavengers have been widely and successfully used in the natural gas industry for a long time to remove small amounts of H2S. The global natural gas industry is projected to spend more than $60 million/yr on chem. scavenging operating costs. However operators have been reporting difficulties in obtaining acceptable H2S removal costs and performance. The process utilizes a scrubbing tower or in line injection to contact the ENVIRO-TEK with the sulfur bearing gas. H2S and mercaptans are removed from the gas in the contactor and the sulfur is chem. bound in the spent chem. The chem. is then regenerated with the use of air in a sep. regeneration tank. Finally, the elemental sulfur formed in the regeneration tank is removed with the use of a solids separation step such as a settling tank, a centrifuge, or a filter press. The regenerated Enviro-tek is then ready for re-use in the scrubbing tower or direct injection pipeline. The experimental process involved the reaction of 2,2′,2”-(1,3,5-Triazinane-1,3,5-triyl)triethanol(cas: 4719-04-4).Synthetic Route of 4719-04-4
