Title: Ovidiu Dicoi: Innovator in Polymer Technology
Introduction
Ovidiu Dicoi is a notable inventor based in Offenbach, Germany. He has made significant contributions to the field of polymer technology, particularly in the production of high molecular weight polyethylene terephthalate (PET) and polyester polymers. With a total of 3 patents to his name, Dicoi's work has advanced the efficiency and quality of polymer manufacturing processes.
Latest Patents
One of Dicoi's latest patents is for a continuous moving bed reactor designed for the manufacture of high molecular weight PET. This innovative reactor allows for the solid state polycondensation of low molecular weight polymer granulate or chips. The system utilizes gravity flow to move the crystallized polymer chips through a cylindrical, vertical reactor. An automatic sampling system continuously analyzes the intrinsic viscosity of the chips, enabling precise control over the chip quality by adjusting the gas flow and residence time based on the viscosity profile.
Another significant patent is a column system process for polyester plants. This new process is tailored for continuously operated plants that produce polyester polymers suitable for fibers, bottles, and films. It involves the reaction of ethylene glycol and terephthalic acid in the presence of a catalyst, with the vapor by-products being continuously rectified in two in-line columns. This process yields high-purity ethylene glycol, which is returned to the production process, while also improving the quality of the esterified product by minimizing the presence of diethylene glycol.
