TANSCIENT™ is changing refiner’s perspectives
on High Temperature Corrosion Inhibitors

  • TANSCIENT delivers safer corrosion protection and reduced risk of downstream fouling with up to 80% less phosphorous than traditional corrosion inhibitors

  • TANSCIENT is patented technology using a high molecular weight phosphorus carrier to make the partial ester more resistant to heat, reacted with ethylene oxide to eliminate product acidity


  • TANSCIENT advantage is superior thermal stability that results in improved phosphorus solubility (see graph on right). Improved phosphorus solubility and reduced product acidity results in better surface reactivity for more compact, stable and adherent protective scale.

Benefits and Performance

Why P matters – more effective
passivation with up to 80% less phosphorous

  • Reduces risk of precipitation, fouling and catalyst impairment
  • Superior thermal stability and oil solubility
  • Low acidity, does not require cooled slip stream for injection
  • Requires no highly reactive sulfur in the blend
  • Familiar easy to implement phosphorous based passivation
