Latest Patents

Lage M Sandgren holds a patent for a process for the production of chlorine dioxide. This process involves a mixture of sulfuric acid and hydrochloric acid that is essentially free from dissolved sulfur dioxide. The method includes reacting chlorine and sulfur dioxide in at least two reaction zones. In the primary reaction zone, the total amount of sulfur dioxide needed for mixed acid production is introduced in an aqueous mixture of sulfuric and hydrochloric acid containing dissolved chlorine and gaseous chlorine. The sulfur dioxide reacts with chlorine in the aqueous phase to produce sulfuric acid and hydrochloric acid. The mixed acid produced is then forwarded to a secondary reaction zone where chlorine is introduced, ensuring an efficient production process.
