Triazine vs. Pro3 GT & GT+: Is it time to Make the Switch for H2S Removal?

The natural gas industry faces a constant challenge: removing harmful hydrogen sulfide (H2S) from its product for safe and efficient transportation. Traditionally, triazine has been the go-to solution, but recent innovations have sparked a question – are there better options available?

Our team at Q2 Technologies made a laboratory investigation to compare the performance of triazine, Pro3® GT, and GT+. This wasn’t just about finding alternatives, it was about discovering solutions that could streamline operations and overcome the limitations of existing methods. 

The Experiment Unfolds 

We first pitted 40% active MEA triazine against Pro3® GT, its chemically similar counterpart designed as a direct substitute. Both performed neck and neck in H2S removal efficiency until the point of breakthrough. As expected, Pro3® GT+, as a concentrated form of Pro3® GT, was able to last longer in this controlled application.

Beyond Efficiency: The Challenge of Solids 

But our investigation didn’t stop there. We delved into the byproducts formed during H2S removal. Triazine, under excessive dosing, readily formed solid compounds – dithiazine and trithiane – which can wreak havoc on equipment, causing blockages and operational headaches. Pro3® GT and GT+, on the other hand, remained liquid even under overdosing, showcasing their resistance to solid formation.

When the Temperature Drops: 

We then turned our focus towards extreme cold, mimicking harsh winter conditions. Unfortunately, triazine faltered again, solidifying – exactly mimicking what we see in cold conditions -icing up hinders the ability to operate. In contrast, Pro3® GT and GT+ maintained their liquid state, proving their ability to withstand harsher environments.

The Verdict: A Promising New Chapter 

While this study offers a glimpse into the potential advantages of Pro3® GT and GT+, it’s crucial to remember that the real world presents a complex landscape. Field conditions and economic factors like cost and treatment longevity also play a vital role in the decision-making process. 

However, the impressive performance of Pro3® GT and GT+ in H2S removal efficiency, resistance to solid formation, and cold temperature resilience suggests they can be strong contenders in the H2S removal arena. We encourage you to explore further, consult with professionals, and consider all factors before embarking on your own journey towards a streamlined and efficient H2S removal solution.
