) react with these metal sulfides to generate polythionic acids (

Using heated dry air to ensure the relative humidity is below the dew point, preventing liquid water from forming on the surface.

The most effective way to prevent the formation of polythionic acid is to completely exclude oxygen and moisture from the system.

If your organization requires ongoing access to a wide range of technical documents, a standards subscription service may be a cost-effective alternative. These services provide online access to a vast library of standards, including NACE SP0170, for a fixed annual fee. This can be a particularly good solution for large engineering or inspection teams. nace sp0170 pdf

NACE SP0170 is a standard that outlines the practices and procedures for preventing and controlling corrosion in petroleum refining and petrochemical processes. The standard covers various aspects of corrosion prevention, including:

Beyond copyright issues, those PDFs are often corrupted, watermarked with old revision dates, or missing critical annexes.

Once the equipment is opened, a continuous positive pressure of dry nitrogen is maintained to keep air and humidity out, preventing the oxidation of sulfide scales. 2. Alkaline Washing (Neutralization Method)

Alkaline washing is a widely used, effective method for neutralizing acids that have already formed or preventing their formation, as noted in the NACE SP0170 technical guide. These services provide online access to a vast

Recommending the use of stabilized stainless steel alloys containing Titanium (Grade 321) or Niobium/Columbium (Grade 347) which bind carbon and prevent chromium carbide depletion.
