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.

ANOTHER PRO-3™ NON-AMINE H2S SCAVENGER PROCESS UP AND RUNNING!

The heat is on in the Eagle Ford Shale as we supply our PRO-3™ Non-Amine H2S Scavenger Process to one more upstream application. Since we are proud of all our projects and pleased to help our clients get more value for their barrel, we want to share how it all looks as it is happening. On the first picture, a trench was being dug in preparation for injecting our PRO-3™ Non-Amine H2S Scavenger into our client’s oil stream. On the second one, the well flowback was being tested in order to start production.

After successful pilot testing and careful planning, all the steps were completed for our clients to start using the PRO-3™ process and get more value for their barrel. Today the project is completely operational and we expect to continue growing with them in the promising Eagle Ford Shale. Together with our partner Additive Direct Services, we brought with us a team of experienced professionals.  We made sure that installation flowed smoothly and that operations were not interrupted. We will do the same in the next projects during the fall.

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.
