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.

ENVIRO-SOLVE PRO3 is a non-fouling, water-soluble, oil-dispersible hydrogen sulphide scavenger.

  • Non-amine/non-aldehyde chemistry
  • Fast reacting and more effective than MEA triazine
  • Resistant to temperatures up to 100ºC/212ºF.
  • Non-fouling
  • It is highly engineered for the treatment of hydrocarbon streams that will be processed in refineries.

ENVIRO-SOLVETM PRO3 will convert HS into a non-toxic, stable, irreversible sulphate salt and water.

Q2 Technologies has built a reputation as an industry leader in hydrogen sulfide and mercaptan treatment for crude oil, offering proprietary scavenger chemistries engineered for the full range of sour crude qualities producers encounter. The company’s formulations are developed and manufactured in-house, allowing rapid adjustments as crude composition changes across a well’s life cycle. Producers across every major basin depend on Q2 to keep crude oil within pipeline and refinery H2S specifications.

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.

FAQs

  1. What industries can benefit from using PRO3?

    Enviro-Solve Pro3 is designed for refineries, gas plants, and upstream production facilities dealing with hydrogen sulfide challenges. Its non-amine formulation makes it especially useful in applications where solids, fouling, or amine reactivity are concerns, offering broader compatibility and cleaner performance.

  2. Is Enviro-Solve Pro3 safe for refinery equipment?

    Yes. Pro3 is specifically engineered to be non-corrosive and non-solid forming, which helps protect heat exchangers, compressors, and other sensitive refinery equipment. It reduces the risk of buildup and unplanned downtime, making it a safe and efficient choice for refinery environments.

  3. Can PRO3 be used in high-temperature environments?

    Absolutely. We have variations of Pro3, such as Pro3HT that perform well in high-temperature and high-pressure conditions, making it ideal for harsh processing environments. It maintains its H2S scavenging effectiveness even where traditional scavengers may degrade or lose efficiency.
