Introduction
Stephen J Dunn is a notable inventor based in Glens Falls, NY (US). He has made significant contributions to the field of pulp delignification and ozone bleaching, holding a total of four patents. His work focuses on improving the efficiency and effectiveness of ozone applications in paper pulp processing.
Latest Patents
One of his latest patents is titled "Method of controlling pressurized ozone to a pulp delignification reactor." This invention describes a method and apparatus for supplying ozone-containing gas under superatmospheric pressure to an ozone delignification device. The system controls the speed of a water ring compressor to ensure that it compresses the required amount of ozone gas without excess. The ozone gas is then fed through a separator buffer tank, which levels out pressure pulses and separates cooling water from the compressed ozone gas before it enters the delignification unit. Additionally, he has developed a patent for "Medium consistency pulp ozone bleaching," which effectively bleaches medium consistency paper pulp using ozone in a carrier gas. This process involves efficient separation of the carrier gas from the pulp after the reaction with ozone, ensuring optimal results.
