Materials Selection for Process Environments
MTS assists companies to select materials to resist degradation due to mercury in process streams. Dr. Wilhelm has over 20 years experience in the investigation of the effects of mercury on materials and conducts research on the interactions of mercury with engineering materials.
Projects include:
- Materials selection in gas processing (LPG) to resist condensed mercury
- Tubing hanger seals for production of gas containing mercury
- Effects of mercury and methanol on aluminum corrosion
- Corrosion of carbon steel in glycol containing mercury
- LME of aluminum and monel
- Effect of mercury in multi-phase flow on martensitic steels
- Integrity of pipelines contaminated by mercury
Research in progress is examining the effects of mercury in natural gas on pipeline corrosion, cracking of Monel 400 distillation tower linings and mercury cracking of brass propane valves. More on mercury corrosion.
