Patents by Inventor David R. Papanek

David R. Papanek has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 11970393
    Abstract: A method of controlling a chemical reaction is disclosed. The method may include feeding a solution at a first flow rate into a reactor and detecting a sound in the reactor using a sound sensor that is adjacent to the reactor. The sound sensor may convert the sound into a sound signal. After the sound signal is acquired, it is compared to a stored sound signal or a stored sound threshold to detect a reaction event. The method may include adjusting the flow rate of solutions into the reactor in response to the reaction event.
    Type: Grant
    Filed: July 3, 2019
    Date of Patent: April 30, 2024
    Assignee: ECOLAB USA Inc.
    Inventors: Kun Xiong, Nicholas Ryan Denny, Stephen Joseph Hinterlong, Emily Rader, David R. Papanek, Shawn Dalke

  • Patent number: 10501345
    Abstract: The present disclosure generally relates to methods of treating process water using a reactor for generating chlorine dioxide onsite. The onsite generation system may include double ensured precursor feeding, effective reactor, automated control/alarm, and effective product delivery. The reactor may include a mixing device, a first feed line connected to the mixing device, and a second feed line connected to the mixing device. The reactor may include a proximal portion in fluid communication with the mixing device and a distal portion in fluid communication with a motive water line. The mixing device, the reactor, a portion of the first feed line, and a portion of the second feed line may be positioned within the motive water line.
