Manufacturing Process Excellence

The sulfuric acid production process using the contact process involves several precision-controlled stages:

Sulfur Preparation: Elemental sulfur is melted, filtered to remove impurities, and prepared for combustion, or alternatively, sulfur-containing gases from smelting operations are captured and processed
Combustion: Molten sulfur is burned in excess air within combustion furnaces at temperatures around 1,000°C, producing sulfur dioxide gas (S + O2 → SO2) with heat recovery through waste heat boilers
Gas Cleaning and Drying: Combustion gases are cooled, cleaned to remove dust particles and impurities, and dried to prevent catalyst poisoning in subsequent conversion stages
Catalytic Conversion: Dried sulfur dioxide gas passes through catalytic converter beds containing vanadium pentoxide (V2O5) catalyst at 400-600°C, where SO2 is oxidized to sulfur trioxide (2SO2 + O2 → 2SO3) in multiple stages with intermediate cooling
Absorption: Sulfur trioxide is absorbed in circulating concentrated sulfuric acid (98-99%) or oleum in absorption towers, forming additional sulfuric acid (SO3 + H2O → H2SO4) while avoiding direct water contact which would create acid mist
Intermediate Absorption: Modern plants employ double-contact, double-absorption (DCDA) process where partially converted gas undergoes intermediate absorption followed by additional catalytic conversion, achieving 99.5%+ sulfur dioxide conversion efficiency
Acid Circulation and Cooling: Concentrated acid is continuously circulated through absorption towers with cooling systems to maintain optimal temperatures and acid strength
Product Withdrawal: Sulfuric acid at desired concentration (typically 93-98%) is withdrawn from the circulation system for storage or further processing
Dilution and Blending: For applications requiring lower concentrations, concentrated acid is carefully diluted with water under controlled conditions (adding acid to water, never reverse)
Quality Testing and Storage: Final product undergoes rigorous quality testing for concentration, purity, and contaminants before storage in acid-resistant tanks or packaging for distribution
