Q2 Technologies has brought to market the Enviro-Solve™ Pro3™ series; an innovative non-amine/non-aldehyde H2S scavenger for crude oil applications. Q2 Technologies and its former partner Quaker Chemical developed the triazine technology that is used world-wide today. A need was identified to reduce fouling created by amine based scavengers in refineries, production streams and crude oil terminals while keeping treating costs in the same level as triazines.

Reaction Overview:

R(Pro3™) + H2S                           R’SO4-2 + H2O

  • Pro3™ will react with the H2S molecules and turns them into aqueous non-toxic sulphate salt.
  • The heavier sulphate salt molecule will drop into produced water stream.
  • Reaction is fast and irreversible.

Pro3™ will react instantaneously with H2S once contact is made. It will also react with lower chain mercaptans. Mercaptan reaction time may take up to 24 hours depending on mercaptan species.

  • Pro3™ will not react with double bonded sulfur compounds.

Field Data:

Q2 Technologies has found that a injection dosage between 0.18-0.5 ppm of 33% active Pro3™ is needed per 1 ppmv of H2S in crude oil in a pipeline. Comparatively a 40% triazine is typically dosed at a 1 ppm 40% active triazine per 1 ppmv of H2S in a pipeline. Dosage rates are greatly dependent on contact efficiency and residence times.

A brief analysis is presented below to showcase economics between 40% MEA Triazine and Pro3™:

(Estimates based on 100,000 barrels of crude oil and 1,000 ppmv H2S)

Scavenger ppm scavenger/ ppmv H2S Lbs. scavenger Treatment Cost
Pro3™ 0.25 7,348 45-50% savings
Pro3™ 0.5 14,696 20-25% savings
MEA Triazine 40% 1 29,392
