Acid Regeneration Plants

ANDRITZ METALS acid regeneration technology provides advanced and state-of-the-art systems for:

• Hydrochloric acid recovery ( available)
• Mixed acid recovery (Pyromars)
• High-quality oxide production from metal chlorides (Fe, Ni, Co, Ti, Mg, etc.)

ANDRITZ METALS acid regeneration – keep the acid loop closed

Most steel producers use either hydrochloric acid (in the carbon steel industry) or HF-HNO3 mixed acid (for stainless steel) for steel pickling. The waste acid produced can either be discharged and neutralized – which results in high costs and a high fresh acid demand – or regenerated.

• Highly economical in operation
• Short payback period for the investment
• Tremendous cost savings for fresh acid demand
• Closed acid loop between the pickling plant and the regeneration system
• Proven and sophisticated design with more than 220 references worldwide
• Environmental protection
• Lowest possible energy consumption with
