Governing Standards for Acetic Acid (CH₃COOH) Service

What to Avoid in Acetic Acid (CH₃COOH) Service

  • Carbon steel valves - severely corroded
  • Bronze/brass - attacked by acetic acid
  • SS 316 for hot concentrated service without corrosion allowance review

Service Considerations

  • PTA oxidation service: air + acetic acid + xylene at 180–220°C is extremely aggressive - Hastelloy or titanium mandatory
  • PTFE-lined valves acceptable for lower-temperature dilute acetic acid circuits
  • Fire-safe valve design required in ATEX Zone 1 PTA production areas
