Title: The Innovative Contributions of Hans Wewer
Introduction
Hans Wewer is a notable inventor based in Schoneck, Germany. He has made significant contributions to the field of environmental technology and polymer production. With a total of 2 patents, Wewer's work focuses on processes that enhance efficiency and reduce waste.
Latest Patents
One of Wewer's latest patents is a process for the removal of nitrogen oxides. This innovative method aims to eliminate nitrous gases from gas mixtures quickly and cost-effectively, without generating secondary waste. The process involves scrubbing the nitrous gases using a 15-50% nitric acid solution, which is then treated with gaseous oxygen, particularly atmospheric oxygen.
Another significant patent is a column system process for polyester plants. This new method is designed for continuously operated plants that produce polyester polymers suitable for fibers, bottles, and films. The process reacts ethylene glycol and terephthalic acid in the presence of a catalyst, allowing for the continuous rectification of vapor by-products. This results in high-purity ethylene glycol (99.85%) being returned to the process, along with wastewater containing 400 ppm ethylene glycol and a heavy fraction of oligomers and diethylene glycol. Notably, the esterified product quality is improved, containing less than 0.6% diethylene glycol without the use of diisopropylamine, a toxic additive.
Career Highlights
Throughout his career, Hans Wewer has worked with several prominent companies, including Davy International Aktiengesellschaft and Nukem Limited. His experience in these organizations has contributed to his expertise in developing innovative processes.
