Application

Crude oil production, pipelines, terminals, barges and refineries experience the release of H2S.  Increasing government regulations and finished product specification as well as concern for internal corrosion control is requiring the removal of H2S from the crude oil.  Recent studies have demonstrated that the use of amine or triazine sulfide scavengers to control sulfide can result in the formation of monoethanolamine (MEA) triazines which have shown to be very problematic and corrosive to refineries.  Many crude transporters and traders are now requiring amine and/or triazine free crude.

"The use of amine-based scavengers is not new to the Petroleum and Refining Industry. Treatment of “sour” crude oils with commodity and proprietary amine formulations to remove H2S is routinely

performed. However, concerns regarding the use of amine-based H2S scavenging compounds and the effects these formulations have during the processing of treated crude oils have recently surfaced.Crude unit corrosion and fouling in overhead systems and tower trays are attributed to the use ofamine-based H2S scavengers.  

Of the chemical families of nitrogen based H2S scavengers, triazine chemistry is most often employed to abate H2S from crude oil and as such the use of triazine chemistry is ubiquitous throughout the Petroleum and Refining Industry. Worldwide, the most versatile and economical of the triazine family used to abate H2S are monomethylamine (MMA) and monoethanolamine (MEA) triazines."  Garcia, J. and Lordo, S. 2007.

ENVIRO-SOLVE® PRO3® can be applied in crude oil production streams and for cargo treatment in barges and tankers of fuel oil and crude. The product can also be used in storage tanks and be recirculated. It is recommended to maximize the contact time of the product to enhance its performance. For treatment of hydrocarbon streams, it should be injected near the inlet valve of a transfer pump. Once the product reacts, it will migrate into the heavier water phase where it can be disposed of in the produced water stream or go directly into a waste water treatment facility. 

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

•  Non-amine/non-aldehyde chemistry 
• Fast reacting and more effective than MEA triazine 
• Demonstrated less chemistry used as compared to amine or Triazine
• Resistant to temperatures up to 100ºC/212ºF. 
• Does not cause sludge formation with over treatment

It is highly engineered for the treatment of hydrocarbon streams that will be processed in refineries, and is recommended to treat from downhole to the refineries.

ENVIRO-SOLVE® PRO3® will convert H2S into a non-toxic, stable, irreversible sulphate salt and water.
