How it Works

SO3CleanTM

Sulfur trioxide (SO3) and oleum are essential intermediates used in the production of many important products.Supply chain risks and the rapidly rising cost of transportation have become very serious concerns for users.Production in situ, near the point of use, has long been a coveted arrangement but not necessarily practical or economical…until now.

How it Works

  • The SO3Clean process was developed by Calabrian Corporation in collaboration with Chemithon Corporation.
  • SO3Clean produces pure SO3 gas directly from sulfur and oxygen in one step using Calabrian’s proprietary submerged combustion technology, known as SO2Clean and Chemithon’s proprietary SO2 to SO3 converter design to safely and economically produce an undiluted, 100% pure SO3 gas stream.
  • Shutdown and start-up controlled by oxygen flow.
