Q2 Technologies, a former subsidiary of Quaker Chemical which developed the MEA-Triazine scavengers used world-wide today, along with its Gulf Coast region distributor, Additive Direct Services, have brought to market two remarkable mercaptan scavenger series – the ProM® series of non-amine/non-triazine mercaptan scavengers and the Pro3® series of non-triazine H2S scavengers. These cutting-edge H2S and mercaptan scavenger solutions are revolutionizing the industry, offering superior performance and a range of benefits.

The ProM® series represents the next generation of mercaptan scavengers, replacing MEA-Triazine in liquid hydrocarbon streams. By utilizing non-amine/non-triazine technology, ProM® addresses the challenges associated with fouling and corrosion, enhancing operational efficiency and equipment lifespan. These innovative mercaptan scavengers provide significant benefits, including reduced fouling/corrosion, enhanced operational efficiency, and superior mercaptan removal performance.

Similarly, the Pro3® series is a non-triazine-based H2S scavenger solution that delivers exceptional performance in the removal of H2S from liquid hydrocarbon streams. Pro3® leverages advanced non-triazine technology to achieve outstanding H2S scavenging capabilities, ensuring high product quality and purity. With its non-triazine formulation, Pro3® offers superior performance while overcoming the limitations associated with traditional triazine-based scavengers.

  • A leading Midstream company in the Permian had an active Producer bringing 50,000 bpd of crude oil on pipe into their facility, but was faced with the challenges of high levels of H2S and Mercaptans.
  • High volumes of non-triazine scavenger from a 3rd party were being used but failed to meet spec. and was fouling gathering lines.
  • Producer faced risk of being shut-in so Midstreamer reached out to
    Q2 Technologies to provide a non-triazine solution
  • A combination of the Pro3® and ProM® was implemented into the Midstreamer’s overall system, not only in the Permian, but also at the Gulf Coast where they had additional infrastructure. Both products work in tandem.
  • Q2 Technologies in combination with the Midstream’s facilities team installed injection pumps, placed storage vessels, and connected the system to their SCADA system.
  • End goal was achieved: Crude volume treated to allow volume to flow on pipe and not to turn away potential throughput volume
  • Pre-Treatment Mercaptan level: 200 -600 ppm w/w per UOP-163/D-3227
  • Post-Treatment Mercaptan level: meets spec of <75 ppm
  • Pre-Treatment H2S level: 4,000 – 5,000 ppm v/v per ASTM 5705
  • Post Treatment H2S level: <10 ppm


  • Pro3® and ProM® chemistries allowed customer to consistently meet H2S and Mercaptan specifications that 3rd party chemistry was unable to reach.
  • Overall cost of treatment was reduced by >25%.
