Study of the Reaction Mechanism of Triazines and Associated Species for H₂S Scavenging.

ABSTRACT: Natural gas produced worldwide contains, among other compounds, H₂S and CO₂. Both gases in the presence of free water can generate problems of corrosion in pipes and subtract calorific value to this gaseous hydrocarbon. Natural gas containing H₂S and CO₂ above the permissible limits should be treated to remove these components. Particularly, H₂S is removed mainly using hexahydro-1,3,5-tris-(-2-hydroxyethyl)-s-triazine (TZ), which is the liquid scavenger of H₂S leading on the market. By means of computational methods, we have studied the reaction of H₂S with TZ, oxazolidine, and oxazinane to elucidate, explain, or confirm different aspects related to their proposed reaction mechanisms. Our results validate t
