Title: Innovations of Wolfgang Wöll in Epoxidation Processes
Introduction
Wolfgang Wöll is a notable inventor based in Maintal, Germany, recognized for his significant contributions to the field of chemical engineering. With a total of 13 patents to his name, Wöll has made remarkable advancements, particularly in the epoxidation of propene.
Latest Patents
Among his latest patents, Wöll has developed a process for the epoxidation of propene that involves continuously reacting a propene feed with hydrogen peroxide in the presence of an epoxidation catalyst. This innovative method utilizes propene in excess to hydrogen peroxide, resulting in a liquid reaction mixture that minimizes safety risks associated with oxygen during the work-up phase. By employing an inert gas to strip the liquid reaction mixture, Wöll's process effectively reduces the oxygen concentration in the strip gas stream, enhancing safety and efficiency. Another patent details a similar process where propene is reacted with hydrogen peroxide, followed by the separation of propene oxide and a recovered propene stream. This method also incorporates a C-splitter column to optimize the separation of propane, thereby reducing the size and energy consumption of the equipment involved.
