Sulphuric Acid & Fertiliser & Ethanol

Specialists in Efficient Heat Exchange for Bulk Chemical Production

These industries operate on a massive scale with mature processes, exhibiting extreme sensitivity to equipment reliability, energy efficiency, and total lifecycle costs. Our plate heat exchangers deliver outstanding performance at critical heat recovery and process heat exchange points.

Core Application Scenarios:

Sulphuric Acid Production Applications:SO₂/SO₃ gas cooling, acid cooling in drying towers, circulating acid cooling in absorption towers.

Fertiliser Production Applications:Conversion gas cooling in ammonia synthesis processes; ammonia synthesis loop heat exchange; formaldehyde condensation in urea processes.

Ethanol Production Applications:Preheating of fermentation mash, preheater/condenser/reboiler in distillation columns, and distillate cooling.

Oudun Product Advantages:

Utilises high-silicon stainless steel or special alloys to resist concentrated sulphuric acid corrosion, efficiently recovering reaction heat across all stages of acid production.

Withstands high pressures, handles corrosion from ammonia-containing media, optimises plant-wide heat balance.

Significantly reduces steam consumption; demountable design facilitates cleaning of mash-derived deposits.
