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.
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.
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|
|MEA Triazine 40%||1||29,392|
