Title: Innovations of Johan C Wanngard in Chlorine Dioxide Production
Introduction
Johan C Wanngard is a notable inventor based in Sundsvall, Sweden. He has made significant contributions to the field of chemical engineering, particularly in the production of chlorine dioxide. His innovative approach has led to the development of a unique process that enhances the efficiency of chlorine dioxide production.
Latest Patents
Wanngard holds a patent for a process for preparing chlorine dioxide. This process involves the reaction of sodium chlorate with chloride ions and sulfuric acid, where chlorine ions are partially derived from hydrochloric acid. The method also includes a mechanism for reacting the chlorine obtained as a by-product with sulfur dioxide in a specially designed reactor equipped with a condenser. The heat generated from the reaction is effectively managed by maintaining the reactor at or above the boiling point of the reaction medium. The resulting vapors are condensed and returned to the reactor, ensuring a continuous cycle. The mixed acid, which consists of sulfuric acid and hydrochloric acid, is then redirected back to the chlorine dioxide reactor. Wanngard's innovative process is encapsulated in his 1 patent.
