Title: Maria G Norell: Innovator in Chlorine Dioxide Production
Introduction
Maria G Norell is a prominent inventor based in Sundsvall, Sweden. She has made significant contributions to the field of chemical engineering, particularly in the production of chlorine dioxide. With a total of three patents to her name, Norell's work has advanced the methods used in chemical processes.
Latest Patents
Norell's latest patents include innovative processes for preparing chlorine dioxide. One patent describes a method for producing chlorine dioxide and chlorine by reacting sodium chlorate with chloride ions and sulfuric acid. In this process, chlorine obtained as a by-product is reacted with sulfur dioxide in a reactor equipped with a condenser. The heat of reaction is managed by maintaining the reactor at or above the boiling point of the reaction medium, allowing the vapors to be condensed and returned to the reactor. The resulting mixed acid, which comprises sulfuric acid and hydrochloric acid, is then returned to the chlorine dioxide reactor. Another patent outlines a process for producing a mixture of sulfuric acid and hydrochloric acid, which is essentially free from dissolved sulfur dioxide, to be used in a chlorine dioxide reactor. This is achieved by reacting chlorine and sulfur dioxide in at least two reaction zones, ensuring efficient production of the mixed acid.
