Study Explores Effects of H2S Scavenger Byproducts on Carbon Steel

In the complete paper, the authors seek to understand the effect of triazine on the electrochemical response of a carbon-steel surface in a mixed-gas system.

Triazines are commonly used as hydrogen sulfide (H2S) scavengers. However, stress corrosion cracking (SCC) has been reported recently when using certain triazines, making it necessary to understand the failure mechanism to control this phenomenon. In the complete paper, the authors seek to understand the effect of triazine on the electrochemical response of a carbon-steel surface in a mixed-gas system.

Introduction

One of the more frequently used H2S scavenger triazines is hexahydro-1,3,5-tris(hydroxyethyl)-s-triazine, or monoethanol amine (MEA)-triazine. It is a yellow, viscous liquid that can be injected into gas streams or used in a contactor tower.
