Information to Insights, for safer, more profitable operation

Monitoring systems deliver accurate and timely corrosion rates.

Correlating changes in corrosion rates with changes in operating parameters creates insights enabling more informed decisions about

  • feedstocks – including opportunity crudes
  • production rates
  • chemical inhibitor strategy
  • turnaround timing
  • metallurgical upgrades.
High-risk corrosion areas in HF Alkylation process

Safer operation

Managing HF Alkylation corrosion failure risk

Contact between highly concentrated acid and carbon steel forms a stable iron fluoride layer.

Contact with an acid/water mix forms an unstable and non-protective hydrate scale – this swells and can detach.

Process upsets – temperature or water content variations, or changes in feedstock quality changes – drive aggressive, transient corrosion.


More profitable operation

Avoiding unplanned outages in crude overhead lines


HCl, NH4Cl, amine hydrochloride salt corrosion

Visibility of corrosion rate, and correlating this with changes in process parameters informs mitigation

  • desalter performance optimisation
  • chemical inhibitor strategy
  • dew point control
  • feedstock blending

Example overhead configuration, with inhibitor injection and corrosion locations.
