Willi Fischer

Title: Willi Fischer: Innovator in Distillation Technology

Introduction

Willi Fischer is a notable inventor based in Seligenstadt, Germany. He has made significant contributions to the field of distillation technology, holding two patents that showcase his innovative approaches to recycling and high-vacuum distillation processes.

Latest Patents

Fischer's latest patents include a "Method and apparatus for short-path distillation." This invention involves a high-vacuum distillation process that utilizes plate-like evaporating surfaces. The method allows distillable fractions to evaporate and condense onto surfaces located a short distance away. The liquid is placed on the evaporating surfaces at a temperature that enables the energy required for evaporation to be partially sourced from the still-unevaporated fraction of the liquid. Another significant patent is the "Process for recycling of used lubricating oils." This process involves drying and gasoline removal, followed by distillation and treatment with sodium or sodium hydride at elevated temperatures. Both distillations occur at temperatures below 300 degrees Celsius, with low volatility oil fractions distilled in a molecular distillation apparatus at pressures below 2 mbar.

Career Highlights

Throughout his career, Willi Fischer has worked with prominent companies such as Leybold Heraeus GmbH and Degussa Aktiengesellschaft. His experience in these organizations has contributed to his expertise in distillation technologies and recycling processes.

Collaborations

Fischer has collaborated with notable colleagues, including Friedrich Fauser and Helmut Knorre. Their joint efforts have likely enhanced the development and implementation of innovative distillation methods.

Conclusion

Willi Fischer's contributions to distillation technology through his patents and career experiences highlight his role as an influential inventor in the field. His work continues to impact the processes of recycling and high-vacuum distillation.
