Title: The Innovations of Karl-Heinz Schonberg
Introduction
Karl-Heinz Schonberg is a notable inventor based in Marl, Germany. He has made significant contributions to the field of polymer chemistry, particularly in the area of vinyl chloride emissions. With a total of 2 patents, his work has focused on improving industrial processes to enhance environmental safety.
Latest Patents
One of his latest patents is titled "Avoidance of vinyl chloride emissions in batch suspension polymerizations." This invention eliminates the necessity of opening a large polymerization reactor to introduce a polymerization catalyst. By isolating a segment of a charging conduit for a polymerization reactor containing vinyl chloride under pressure, he has developed a method that avoids vinyl chloride emissions into the atmosphere. The process involves partially filling the isolated segment with water, charging it with a water-insoluble polymerization catalyst, and displacing the water and catalyst into the reactor with vinyl chloride under pressure.
Another significant patent is the "Process for the production of emulsion polyvinyl chloride." This innovation reduces vinyl chloride emissions from the gaseous phase of large-scale vinyl chloride batch emulsion polymerizations. It involves discharging the liquid phase only of the polymerizate to a discharge zone at a pressure differential lower than the reactor, maintaining the reactor unopened, and conducting another vinyl chloride polymerization in the presence of residual vinyl chloride from the prior polymerization.
Career Highlights
Karl-Heinz Schonberg has worked with prominent companies in the chemical industry, including Chemische Werke Huels Aktiengesellschaft. His experience in these organizations has allowed him to develop and refine his innovative processes.
