Issues regarding the selection of equipment materials for industrial wet oxidation plants
Thread Content
I have two questions for the experts here. 1. What materials are generally used for industrial wet oxidation equipment? Titanium or zirconium? 2. What material should be used when the chloride ion content is high and the temperature is 280 degrees? Titanium or zirconium, or Hastelloy?
Zirconium materials: high salt content, high COD, high temperature and pressure – the conditions are simply too harsh
Zirconium also needs to be examined in detail – what is the chloride ion content? Hastelloy can be considered; the specific grade to use depends on the operating conditions. Pure titanium cannot be used at temperatures above 120 degrees; titanium-molybdenum-nickel or titanium-palladium alloys are also not recommended.
Consider Hastelloy materials – the universal alloy
