Sulfuric Acid Systems

INDUSTRY OVERVIEW

Recover More Energy from Corrosive Process Gas Streams

Sulfuric acid production generates large volumes of hot process gas containing sulfur oxides, sulfuric acid mist, and acidic moisture. While these streams contain significant recoverable thermal energy, severe corrosion and acid dew-point conditions often limit the performance of conventional heat recovery equipment.
Fluoroplastic-steel systems enable reliable low-temperature heat recovery while maintaining long-term operational stability under highly corrosive conditions.

    A real sulfuric acid production facility featuring:
  • ● Absorption towers
  • ● Acid plant process units
  • ● Sulfur recovery systems
  • ● Process gas ducting
  • ● Heat recovery equipment
  • ● Heavy industrial piping
