We are designing a caustic tower. The caustic solution has ~10% NaOH, ~10%Na2S, ~5% Na2CO3, ~50ppmw Cl, and ~20ppmW NaClO3. It also has about 4% (CH3SNa + CH3SH). The design temperature is 190DegC.
We are trying to use Ni alloy for this tower. But we still worry about the effects of Chlorides and sulfides. Do you know the resistance of Ni alloy to chlorides and sulfides in the solution mentioned above?
If Monel or Inconel are suitable for the corresponding service, which one is the best? alloy 400, alloy 600, alloy 625?
