Multielectrode array sensors are developed by SwRI for localized corrosion monitoring.

In collaboration with a major international chemical company, our corrosion monitoring systems are being tested in a chemical processing plant.

In the United States alone, corrosion costs more than $270 billion annually. Statistics show that approximately half of these costs can be avoided by applying corrosion protection and mitigation technologies.

 

In an effective corrosion protection and mitigation program, corrosion monitoring is a key component. Corrosion monitoring provides real-time and earlier warnings for corrosion damage so preventive measures can be implemented before it is too late. Corrosion monitoring is also used to monitor the performance of corrosion protection mechanisms implemented in particular systems so any deficiency can be corrected in a timely manner. If integrated in a corrosion control system, fast-response corrosion monitoring techniques may be used to automatically adjust the dosing of corrosion inhibitors or biocide to prevent overdosing, which often causes environmental concerns in addition to higher costs, and to avoid underdosing, which results in ineffective control.

 

Southwest Research Institute (SwRI) has extensive experience in corrosion monitoring techniques for both localized and general corrosion and in implementing the techniques in laboratory and plant systems, particularly:

 

  • Chemical process streams

  • Industrial cooling water systems

  • High-pressure systems

  • High-temperature systems

  • Vapor phases

  • Atmosphere

  • Under deposits

  • H2S systems
