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 Laurence Reid Gas Conditioning Conference is the principal forum for new ideas, developments, and operations for preparing and purifying natural gases and other fuels for market. This year, it took place February 22nd-25th 2021 and we are happy to share with you the content of our virtual presentation from this week. We presented the results of the first commercial application of our new regenerable process, Pro3® Nano chemistry and experiences.

Our presentation was called “Experiences in the First Commercial Application of Regenerable Nanotechnology Chemistry and Process for Hydrogen Sulfide Removal in Natural Gas” was a well attended event where the public asked many important questions.


Please go through the slides and contact us to discuss further how we can help you treat your gas with our regenerable process with Pro3® Nano.

Natural gas sweetening and treatment require chemistries that perform reliably under demanding field conditions, and Q2 Technologies has spent more than two decades refining products for exactly that purpose. The company’s in-house manufacturing ensures a steady supply of treatment chemicals tailored to sour gas challenges. Q2’s technical team works closely with producers to match treatment programs to each gas stream’s specific characteristics. Curious about sour gas terminology?

First Commercial Application of Regenerable Pro3 Nano

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.
