Title: Innovations by Alfred Widmann
Introduction
Alfred Widmann is a notable inventor based in Mutterstadt, Germany. He has made significant contributions to the field of chemical engineering, particularly in the synthesis of melamine and the treatment of waste gases. With a total of 2 patents, his work has had a considerable impact on industrial processes.
Latest Patents
Widmann's latest patents include a process for isolating liquid urea from the off-gas of melamine synthesis. This innovative method involves the fractional condensation of gas that has been freed from melamine, followed by washing with molten urea. The off-gas, which contains 2-10 kg of melt per kg of pure gas, is introduced tangentially into a separation zone at speeds of 8-30 m/sec. This process effectively separates the gas and liquid phases, allowing for their individual collection at the bottom of the separation zone, with a minimum residence time of 0.5 seconds.
Another significant patent focuses on the cooling of melamine synthesis waste gases. In this process, the waste gases are first treated to remove melamine through condensation. Subsequently, they are cooled indirectly using urea-containing melts, with parts of the cooling occurring simultaneously in a single zone. This innovative approach enhances the efficiency of waste gas treatment.
