Typical Sulfuric Acid Production Process Flow
The sulfuric acid production process in modern plants is typically realized through the catalytic Contact Process, which ensures high yield and purity. Here’s a detailed stepwise visualization:
Process Flow Diagram
- 1. Sulfur Burning or Feed Gas Cleaning
- Molten sulfur or alternative feedstock is combusted to generate SO2 gas.
- 2. Gas Cooling and Purification
- Hot SO2 gases are cooled and washed to remove dust, arsenic, and heavy metals.
- 3. Catalytic Oxidation
- SO2 is converted to SO3 over a platinum or vanadium pentoxide catalyst, using precise temperature control (410–450°C).
- 4. Gas Absorption
- SO3 is absorbed into circulating 98% sulfuric acid to form additional H2SO4.
- 5. Heat Recovery and Product Storage
- Energy integration for steam generation and acid cooling, followed by storage in corrosion-resistant tanks.
