Title: The Innovative Contributions of Carl M. Wilwerding
Introduction
Carl M. Wilwerding is a notable inventor based in Klamath Falls, Oregon. He has made significant contributions to the field of environmental technology, particularly in the degradation of hazardous materials and the treatment of drilling muds. With a total of 3 patents, his work reflects a commitment to innovation and sustainability.
Latest Patents
One of Wilwerding's latest patents focuses on the degradation of polychlorinated biphenyls (PCBs). This process involves the chemical degradation of PCBs through contact with a Lewis acid catalyst in a non-aqueous liquid medium. The method utilizes a cation that combines with the chlorines on the PCBs, forming a solid chloride that precipitates out of the liquid medium. Preferred Lewis acids for this process include metal halides, particularly a combination of aluminum chloride and ferric chloride, with potassium hydroxide being the preferred cation. This innovative process can be applied in both batch and continuous operations.
Another significant patent by Wilwerding addresses the treatment of drilling muds. This process renders used drilling muds, which contain substantial quantities of organic liquids and water-soluble salts, environmentally acceptable for disposal. The method involves drying the muds to evaporate all liquids, preferably using a shell-and-tube type heat exchanger. The vapors generated during this process flow counter-current to the mud, while water-soluble salts are removed by dissolving them with water. The vapors can be condensed and phase-separated for further purification and reuse.
