Title: The Innovative Contributions of Gerrit Op Den Dries
Introduction
Gerrit Op Den Dries, an accomplished inventor based in Bergen op Zoom, Netherlands, has made significant strides in the field of chemical engineering. With two patents to his name, he has demonstrated a strong commitment to improving industrial processes, particularly in the production of bisphenols.
Latest Patents
Op Den Dries' latest patents focus on methodologies that enhance the efficiency of reactors used for acid-catalyzed production of bisphenols. His innovative “Method for cleaning reactors used for acid-catalyzed production of bisphenols” involves the introduction of steam into the shell surrounding the reactor. This process not only heats the reactor wall but also facilitates the melting or dissolution of bisphenol:phenol adducts that form on the wall of the reaction chamber. By introducing steam for a recommended duration of 5 to 60 minutes, the cleaning process is significantly improved. Furthermore, he has developed a variation of this method where a solubility-increasing composition, such as hydrochloric acid, water, or mixtures of acetone and phenol, can be introduced to increase bisphenol solubility during steam application.
Another notable patent is the “Descaling of bisphenol-A reactor using water,” which outlines an integrated process for the preparation and recovery of BPA in pure form. This process involves a series of steps to crystallize the 1:1 adduct of phenol and bisphenol-A, employing periodic descaling of the crystallizer surfaces with a specially modified reactor containing water at concentrations ranging from 1 to 40 percent.
