Waste Acid Recovery

INDUSTRY OVERVIEW

Recover More Energy from Corrosive Acid Recovery Processes

Waste acid recovery systems generate large volumes of hot process gas containing sulfuric acid mist, hydrochloric acid vapor, chlorides, and acidic condensate. These streams contain valuable recoverable thermal energy but often create severe corrosion challenges for conventional heat exchangers.
Fluoroplastic-steel systems enable reliable low-temperature heat recovery while maintaining stable operation under aggressive acidic conditions.

    A real waste acid recovery facility featuring:
  • ● Acid regeneration units
  • ● Waste acid treatment systems
  • ● Process gas ducting
  • ● Absorption towers
  • ● Heat recovery equipment
  • ● Corrosion-resistant piping systems
