Pfaudler Systems offers purification technology for:

  • Nitric Acid
  • Sulfuric Acid
  • Hydrochloric Acid

Based on chemo-thermal treatments, volatile compounds can be removed through stripping and/or evaporation. Salts and non-volatile compounds can be removed through evaporation of the product acid.

Adding reactive compounds, the volatility of certain impurities can be influenced to optimize separation.

Non-volatile organic contaminants can be decomposed through oxidation and high temperature treatment.

We have developed a special thermal oil heated glass-lined steel heat exchanger, Pfaudler HTX, which allows treatment temperatures up to 250°C.
