Title: Rolf Ambrassat: Innovator in Ethylene Glycol Recovery

Introduction

Rolf Ambrassat is a notable inventor based in Frankfurt am Main, Germany. He has made significant contributions to the field of chemical engineering, particularly in the production of polyethylene terephthalate (PET). With a total of 2 patents, his work focuses on improving the efficiency of ethylene glycol recovery processes.

Latest Patents

Ambrassat's latest patents include an "Apparatus for the recovery of ethylene glycol in the production of polyethylene terephthalate." This innovative apparatus involves mixing water accumulating in the esterification reaction with a process fluid containing 2-methyl-1,3-dioxolane (MDO) in a tank upstream of a rectification column. The increase in water content shifts the reaction equilibrium, leading to the cleavage of MDO into ethylene glycol and acetaldehyde. The resulting mixture is then processed in a rectification column, allowing the ethylene glycol produced to be returned to the PET production process. His second patent, titled "Process and apparatus for the recovery of ethylene glycol in the production of polyethylene terephthalate," describes a similar method and apparatus for achieving the same goal.
