Title: The Innovations of Donald D. Tiggelbeck

Introduction

Donald D. Tiggelbeck is a notable inventor based in Pittsburgh, PA, with a remarkable portfolio of eight patents. His work primarily focuses on methods for regenerating activated carbon and particulate adsorbents, showcasing his expertise in environmental technology and materials science.

Latest Patents

One of his latest patents is a method and apparatus for regenerating activated carbon. This innovative process involves a downwardly moving bed where superheated steam moves upwardly through the bed. The steam is maintained in a closed loop system, which includes a steam treatment vessel, a steam pump, and a steam superheater. The low-pressure superheated steam, typically less than about 10 psig, provides the necessary heat for volatilizing water and desorbed organic volatiles. The resulting dry, partially regenerated activated carbon can be reused directly or treated in a vacuum chamber to remove residual water and additional adsorbate. Another significant patent is a method for regenerating particulate adsorbents. This method includes heating the adsorbent, passing inert gas through the heated adsorbent to collect vaporized adsorbate, and chilling the inert gas to condense the adsorbate. The process further involves lowering the pressure within the vessel, collecting withdrawn gases containing volatilized adsorbate, and chilling these gases to condense the adsorbate.
