H2S Scavenger

-------TPS-3

Product Composition and Features

The H2S Scavenger consists of the steric structure of heterocyclic amines derivatives, catalyst, stabilizer, organic solvent. It is marked by high efficient sulfur capacity, high boiling point, low condensation point, etc.

The main ingredient’s molecular formula:

R1/R2/R3 refers to straight chain alkyl group with the same structure or different chain length, or functional groups in which the carbon chain contains O2-/N+.

Such a compound can interact with HS-/S2- generated by sulfide ionization to stable and water soluble compound, without effect on crude oil purification. It is studied that such a kind of H2S Scavenger has positive effect on corrosion protection in produced water treatment system.

Inside our compound, we choose two activators, activator A is selective for H2S and can accelerate the reaction. Activator B enhances the miscibility of solvents and crude oil, promotes the contact efficiency of H2S Scavenger and H2S, and has dispersing effect on scale. Organic solvent has stable chemical performance and good thermal stability, making it a good physical absorbent solution. It can accelerate the absorbent process.

Technical Features

2.1 Fast speed and high efficiency: it has higher efficient sulfur capacity and faster

absorption speed than normal desulfurizers.

2.2 Wide application areas: We have series of H2S Scavenger formulations for different stages of oil field.

For drilling mud: it is applicable to both oil and water based drilling mud, can effectively protect drilling rigs from the corrosion by H2S from ground and sulfide decomposed under HT&HP. It has no negative effect on mud, so suitable to drilling under HT&HP.

For well completion fluids: it has better effect than zinc salts, has good compatibility with well completion fluid.

For pipelines: We have specific formulations for the desulfurization of single well and transportation pipelines. Our products have earned good reputation by Chinese national oil company: Petro China and Sinopec.

2.3 The outcome after desulfurization has no negative effect on crude oil processing: Its main ingredient is Alkyl group. After reaction with H2S, it converts into water soluble products, which directly enter into liquid during demulsification, dehydration and desalination, without negative effect on crude oil.
