H2S and mercaptan scavengers of PS-1, PS-2, PS-3 brand
TU 2458-049-53501222-2005
H2S and mercaptan scavengers of PS brand are designed to capture H2S and mercaptans at well killing for maintenance or conservation, at the flushing of bottom hole, as well as during oil, gas and petrochemical production and transportation.
Depending on the grade and type of chemical the H2S and mercaptan scavengers of PS brand have the following nature:
PS-1 type 1 is a cyclic and aliphatic aldehyde based H2S scavenger; doesn’t contain formaldehyde; concentrated form.
PS-1 type 2 is a cyclic and aliphatic aldehyde based H2S scavenger; doesn’t contain free formaldehyde and amines; concentrated form.
PS-2 is a cyclic and aliphatic aldehyde based H2S scavenger; doesn’t contain formaldehyde; low concentration commodity form i.e. water-alcohol solution.
PS-3 is low a molecular aldehyde based H2S scavenger; doesn’t contain formaldehyde; water or water-alcohol solutions.
Application Area
- Н2S and mercaptan neutralization in the commercial oils.
- Treatment of natural gas and oil-well gas.
- Killing operations in oil and gas wells having high hydrogen sulfide and mercaptan emission.
- Treatment of water, which contains hydrogen sulfide and mercaptans.
- Treatment of produced water prior its injection into the formation.

Customer Benefits
Process Technique
Treatment with H2S and mercaptan scavengers of PS brand can be performed both by continuous injection and by batch treatment of the fluids with increased chemical concentration.
Consumption of the chemicals is calculated depending on the type of the treated medium (water/well-killing brine/oil/fuel oil), initial concentration of H2S and its minimum required content of H2S and mercaptans, operating temperature of the treated product, mass exchange effectiveness and time given for the reaction.
