Triazine-based H₂S Scavenging: Development of a Conceptual Model for the Understanding of Fouling Formation

Abstract

The authors studied the applicability of a previously suggested model to describe the reaction between 1,3,5-tri-(2-hydroxypropyl)-hexahydro-s-triazine and H₂S and thereby predict formation of fouling. To investigate the reaction system, electrospray ionization mass spectrometry was employed to analyze the composition of the generated mixture as H₂S is bubbled through the scavenger. The results of the study confirm that the suggested model is capable of explaining how the scavenger reacts with H₂S, which may be used to explain from where and how the fouling originates, and how a scavenging process can be designed to avoid fouling.
