When is TBPS or DTBPS preferred over DMDS?

Refineries may select TBPS/DTBPS when:

  • A lower sulfiding temperature is required.
  • Methane formation (“methane make”) is a concern.
  • Operators prefer less odor and improved safety profile (TBPS/DTBPS are less volatile than DMDS).
  • The unit requires gradual sulfur release for temperature-sensitive catalysts.
