Title: Innovations by Theo Olffers
Introduction
Theo Olffers is a notable inventor based in Gersthofen, Germany. He has made significant contributions to the field of chemical engineering, particularly in processes that enhance environmental safety. With a total of 2 patents, his work focuses on reducing harmful substances in industrial processes.
Latest Patents
One of Olffers' latest patents is a process for producing chlorine-free hydrochloric acid low in AOX. This innovative method involves subjecting crude gases containing hydrogen chloride and organic impurities to thermal treatment at temperatures ranging from 800 to 1600 degrees in a reducing atmosphere. The resulting hydrochloric acid is chlorine-free and contains virtually no organic impurities, ensuring that the waste gas is also chlorine-free.
Another significant patent addresses the reduction of mercury content in industrial waste waters, particularly those from chlorine-alkali electrolysis using the amalgam process. This invention converts all mercury present in the waste water into Hg++ ions by adding chlorine. Subsequently, Fe++ ions are introduced, and the pH of the solution is adjusted to achieve a specific redox potential. The mercury precipitated, along with the formed iron oxide hydrate, can be filtered from the waste water, achieving residual mercury contents of about 50 mg/m³ in the filtrate.
