Title: Willibald Dafinger: Innovator in Chemical Processes
Introduction
Willibald Dafinger is a notable inventor based in Röhrnbach, Germany. He has made significant contributions to the field of chemical engineering, particularly in the production of vinyl acetate and the removal of oxygen from hydrocarbon-containing gas mixtures. With a total of 9 patents to his name, Dafinger's work has had a considerable impact on industrial processes.
Latest Patents
One of Dafinger's latest patents is a method for producing vinyl acetate. This invention addresses the fouling of the acetic acid saturator by recycle gas in the continuous gas phase process for the manufacture of vinyl acetate. The method involves adding an N-oxyl fouling inhibitor to the saturator and/or at one or more other addition sites in the process. The concentration of the N-oxyl compound that accumulates in the saturator bottoms is maintained between 10 to 100 ppm, with a preferred range of 10-50 ppm. The effectiveness of this method is evidenced by a reduction in the lowering of the heat transfer coefficient of the saturator over time.
Another significant patent by Dafinger relates to the removal of oxygen from hydrocarbon-containing gas mixtures. This invention describes a method where a hydrocarbon-containing gas mixture, consisting of 50 vol % of one or more hydrocarbons and 2 to 10 vol % of oxygen, is introduced into an isothermally operated reactor. In this reactor, the oxygen is at least partially converted into carbon dioxide and water in the presence of one or more catalysts.
