Title: Hermann Dallmeyer: Innovator in Chemical Engineering
Introduction
Hermann Dallmeyer is a notable inventor based in Odenthal, Germany. He has made significant contributions to the field of chemical engineering, particularly in the purification of chemical compounds. With a total of 5 patents to his name, Dallmeyer has demonstrated a commitment to innovation and excellence in his work.
Latest Patents
Dallmeyer's latest patents include a process for the purification of mixtures of toluenediisocyanate. This innovative process involves fractionating a crude distillation feed that contains toluenediisocyanate, an organic solvent, and less than 2% by weight of phosgene. The system is designed with an upstream distillation column, an interchanger, and a downstream distillation column connected in series. The vapor recovered from the upstream column is utilized to reboil the bottoms product of the downstream column or the feed to the downstream column in the interchanger. The process effectively separates the crude distillation feed into three product fractions, enhancing the efficiency of chemical production.
Another significant patent is for a reactor designed to carry out exothermic reactions. This reactor improves heat transfer and simplifies the cooling system's construction, particularly in stirrer reactors. It features vertical boiling tubes sealed at the bottom, with a condensate collecting and liquid distributing chamber above. This design allows for efficient heat exchange between the cooling fluid and vapor produced during reactions.
