dc.description.abstractHydrogen sulfide (H2S) is an environmentally hazardous, corrosive and toxic gas in oil and gas productions. It must be removed to meet the pre-determined specification. There are many chemicals being used in the gas sweetening process. Formaldehyde-MEA Triazine is one of the common H2S scavengers in use. The objective of this research was to review different chemistries and field applications applicable as H2S scavengers in oil and gas, understand the Formaldehyde-MEA Triazine’s properties and behaviors in the sweetening process, and determine technical achievements on custom-made finished blends for successful field applications. The Formaldehyde-MEA Triazine is synthesized by the reaction of formaldehyde and monoethanolamine (MEA). Triazine, water, free formaldehyde or free MEA are fundamental components. Each ingredient has its unique function in process scavenging H2S. There are three steps for triazine’s chemical reaction absorbing H2S. Free formaldehyde can boost the capacity and breakthrough efficiency. However, it makes triazine degradation for shorter shelf life as well. A sufficient water amount, minimum 40% more than triazine, is a must to avoid pre-mature breakthrough in bubble tower uses. Triazine based H2S scavengers are custom made blends for field use. Besides the Formaldehyde-MEA Triazine, other factors such as the solvent package, other additives, plant synthesis, low temperature operation, spent solids treatment, sour liquid sweetening and capacity monitoring are all important considerations for successful H2S sweetening applications in the western Canadian oil and gas industry.en_US
