Metallurgical Sulfuric Acid Plants

Turning Emissions into Valuable Resources

Metallurgical Sulfuric Acid Plants

Industrial processes, such as metal ores roasting and metals smelting, often emit large quantities of sulfur dioxide (SO₂), a harmful pollutant. MECS and Ballestra are offering metallurgical sulfuric acid plants to address this issue, transforming polluting SO₂emissions into commercial-grade sulfuric acid.

Key Process Steps for Metallurgical Plants:

  • SO₂-containing gas quenching and cleaning
  • Dry catalytic conversion of SO₂ to SO₃
  • Heat recovery for gas heating and steam production
  • Absorption in concentrated acid
This approach mitigates environmental impact and converts waste into valuable products.

Spent Acid Regeneration Plants

Large amounts of spent sulfuric acid are generated in the oil and gas industry, particularly in alkylation processes. Ballestra's spent acid regeneration plants recover and recycle sulfur compounds, converting them into fresh SO2 and sulfuric acid through thermal decomposition and dry catalysis.

Key Process Steps for Spent Acid Regeneration:

  • Decomposition Furnace for breaking down sulfur compounds
  • Waste heat recovery for energy efficiency
  • Gas quenching and cleaning to remove impurities
  • Dry catalytic conversion of SO₂ to SO₃
  • Absorption in concentrated acid

By implementing these technologies, industries can achieve sustainable operations, minimize emissions, and recover valuable resources.
