Triazines have been an industry standard as hydrogen sulfide scavengers for the past 40-50 years but their use has been associated with scaling issues and detrimental effects in the refineries. In our efforts to develop a new hydrogen sulfide scavenger, the current work has led to the development of a new non-triazine, non-scaling, low nitrogen content, and thermally stable hydrogen sulfide scavenger.

The laboratory performance evaluations and field data of the novel non-triazine based high temperature stable H2S scavenger will be discussed. The new H2S scavenger acts as a corrosion inhibitor and is thermally stable up to 200°C. Furthermore, it does not promote scale as observed during dynamic scale loop evaluations. The H2S scavenger also exhibited very little effect on the refinery operations regarding desalting, fouling, corrosion, and wastewater treatment based on the laboratory data. Refinery evaluation data will be provided for the new product along with supplemental field studies.
