Title: Heinz Wendt: Innovator in Chemical Processes

Introduction

Heinz Wendt is a notable inventor based in Sulzbach, Germany. He has made significant contributions to the field of chemical engineering, particularly in the preparation of ketene and the manufacturing of potassium sorbate. With a total of 2 patents to his name, Wendt's work has had a meaningful impact on industrial processes.

Latest Patents

Wendt's latest patents include a process for the preparation of ketene. This innovative process involves the thermal, catalytic cracking of acetic acid under reduced pressure. The hot cracked gases are cooled to approximately 0 to -10 degrees Celsius, resulting in the condensation of water, unreacted acetic acid, and acetic anhydride. The process specifies that the quantity of acetic acid used for thermal cracking should range from 0.5 to 2.5 tons per hour per cubic meter, relative to the volume of a shell-and-tube heat exchanger. Additionally, the pressure drop in the tubular heat exchanger is designed to be between 50 to 150 mbars, with a surface/volume ratio of 60 to 120 m^-1.

Another significant patent by Wendt is related to the fluidized bed treatment of granular potassium sorbate. In this process, granular potassium sorbate is continuously manufactured by spraying an aqueous potassium sorbate solution onto a bed of potassium sorbate particles that are fluidized by heated air. This method enhances the efficiency and quality of potassium sorbate production.
