Q2 Technologies Team

Experts in H2S Scavenging Solutions

With decades of combined experience, the Q2 Technologies team specializes in innovative hydrogen sulfide (H2S) scavenging solutions for the oil and gas, wastewater treatment, and industrial sectors.

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.

Performance in H2S Removal Efficiency

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, Pro 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.

Final Verdict: Are Pro3 GT and GT+ the Future?

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.

When introduced into a stream afflicted with H2S, the hemiformal decomposes to release formaldehyde, which then reacts with hydrogen sulfide to form stable, non-volatile byproducts such as thiomethylene glycol.  The reaction is typically fast and efficient, particularly in aqueous or mixed-phase environments. Unlike some traditional scavengers, hemiformal can maintain activity across a broad pH range and is less likely to generate problematic solids. When considering if hemiformal is the right product, certain operating conditions are reviewed, such as pH and temperature.

Key Benefits:

  • Controlled formaldehyde release 
  • Lower vapor pressure and improved safety profile 
  • Broad applicability across liquid and gas-phase systems 
  • Reduced scaling in sour water stripping and other high-temp operations 
  • Hemiformal can make the scavenger safe for transport as it is a very stable compound 

Heading 5

Hemiformal is used in a variety of upstream and midstream applications, including: 

  • Gas sweetening systems 
  • Produced water treatment 
  • Crude oil storage and transport 
  • Sour water stripper overheads 
  • Temporary H2S mitigation during maintenance or turnaround

Its adaptability makes it especially useful in operations where system conditions fluctuate or where traditional triazine-based products may underperform. 

Heading 6

While hemiformal offers many advantages, it is not a one-size-fits-all solution. The rate of formaldehyde release can vary depending on formulation and environmental conditions. Additionally, while safer than raw formaldehyde, hemiformal must still be handled with care and appropriate PPE. 

For optimal results, formulation expertise and application-specific customization are key—something we at Q2 Technologies excel at delivering.
