  H₂S is a colorless, poisonous and corrosive gas that is either present in natural gas or can evolve from crude oil. H₂S poses a threat to workers and it also causes corrosion problems.

   

  There exist various physical and chemical processes for the purification of crude oil or gas (=“sweetening”). The technology employed depends on the content of hydrogen sulfide and/or purity requirements for the the final product.

   

  H₂S scavengers are appropriate for use at low treatment volumes and/or low H₂S concentrations where conventional catalytic reduction (Claus process), chemical absorption (e.g. iron sponge, SulfaTreat^TM process, zinc oxide, etc.) and physical solvents are not economical.

   

  Common scavengers are based either on aldehyde or triazine chemistry.

  H₂S Scavengers - Mode of Action

  • Chemicals like glyoxal or triazine derivatives react with H₂S or mercaptanes to form stable, water soluble compounds that can be separated from gas or crude oil and disposed. 
  • Scavengers may be utilized in contacting towers or sprayed directly into the gas pipeline or oil flowline (continuous injection treatment).
  • As with all chemical reactions, speed and efficiency of H₂S absorption is influenced by: pH, heat, mixing, and reaction/contact time.
  • Other products workon a 1:1 molar basis, meaning one molecule triazine scavenges one molecule H₂S or mercaptane.  NuFlo H2S 40 is more efficient depending on the conditions (pH, temp).  Its mode of action is only in the water not gaseous phase.
