Title: Hellmut A Herrmann: Innovator in Thermal Engineering
Introduction
Hellmut A Herrmann is a notable inventor based in Kassel, Germany. He has made significant contributions to the field of thermal engineering, particularly in the design and optimization of heat exchangers and thermal decoking processes. With a total of 5 patents to his name, Herrmann's work has had a lasting impact on industrial applications.
Latest Patents
One of Herrmann's latest patents is the Quench Cooler, which serves as a transfer line heat exchanger for quenching the effluent from a thermal cracking furnace. This innovative design features an inlet connector that connects the cracking furnace tubes to the tubes of the quench cooler. The tubes are arranged in a circular pattern, and the flow passage is engineered to initially decelerate and then re-accelerate the gas. This design includes a conical diverging diffuser, a radial diffuser, and an annular converging section, all with smooth transitions to minimize pressure loss and avoid dead spaces. Another significant patent addresses the thermal decoking of cracking gas coolers that operate under low gas pressure. This process involves controlling the temperature of a cleaning gas delivered to the cooler by mixing a heated cleaning gas with a cooler stream upstream of the cooler.
