OXYSULF OL H₂ SO₄ / OLEUM production

The OXYSULF OL enables the integrated production of sulfuric acid and oleum within a single facility, combining two process lines into a highly efficient and optimized system. This dual-line configuration allows for flexible operation and maximized resource utilization, ensuring that both products can be generated simultaneously without  compromising performance or product quality.

At the core of the process, liquid sulfur is thermally oxidized to form sulfur dioxide (SO_), which is subsequently converted to sulfur trioxide (SO_) in a catalytic reactor system. The generated SO_ is then distributed between two dedicated downstream processing paths: One line directs the SO_ to a concentration and condensation system for the production of high-purity sulfuric acid (_98 wt%). The second line feeds the SO_ into an oleum formation and absorption system, producing oleum concentrations up to 25 wt%.

This integrated approach allows for precise balancing between sulfuric acid and oleum production depending on plant operational requirements.
