Title: Innovations by John T Schofield
Introduction
John T Schofield is a notable inventor based in Villanova, PA (US). He has made significant contributions to the field of environmental technology, particularly in the treatment of process gases and commingled wastes. With a total of two patents to his name, Schofield's work focuses on reducing emissions and improving waste management processes.
Latest Patents
One of Schofield's latest patents is a method of removing sulfur from a process gas stream using a packed bed. This invention aims to reduce sulfur and odor emissions from the paper-making Kraft process by recovering sulfur from non-combustible gases emitted during the process. In the first embodiment, the non-combustible gases are flamelessly oxidized in a thermal oxidizer, resulting in a sulfur oxide-containing gaseous products stream. This stream is then scrubbed to remove sulfur components, allowing for the recovery of sulfur back into the Kraft process. The second embodiment involves a moving, packed bed calcinator that interacts with lime mud from the Kraft process, facilitating the recovery of sulfur/calcium components alongside quick lime.
Another significant patent by Schofield involves improved methods for treating commingled wastes. This process begins with the separation of organic and inorganic waste materials in a primary treatment unit using a carrier fluid. The remaining organic compounds are efficiently destroyed in a flameless oxidizer, with the process gases being recycled back to the primary treatment unit for enhanced efficiency.
