Rafael Lopes Duarte Barros 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).

  • SYSTEM AND METHOD FOR OPTIMIZATION OF THE FERMENTATION PROCESS
    Publication number: 20220348862
    Abstract: The invention comprises one or more gas volume fraction measurement devices operatively connected to one or more controllers and one or more deaeration mechanisms which receive control signals from said one or more controllers and perform an act on the system, such as by controlling a level of deaeration chemistry into some portion of the fermentation system. In one embodiment, the deaeration mechanism is an antifoam feed pump which pumps antifoam chemistry into a feed line of the fermenter in response to the measured gas volume fraction in the fermenter's recirculation loop, in an amount determined by the controller to be effective to reduce foaming and lower column height in the fermenter.
    Type: Application
