  • Phosphoric acid production gypsum filtration flocculant pre-dilution (make down) with post-filtration phosphoric acid
    Patent number: 9187327
    Abstract: A method for minimizing the addition of water to a phosphoric acid production process is described. The method uses phosphoric acid to make down a flocculant that is added to the process in order to promote filtration or clarification of crude phosphoric acid. Preferably, the phosphoric acid is a crude, clarified phosphoric acid that is recycled from the phosphoric acid production process itself.
    Type: Grant
    Filed: January 4, 2011
    Date of Patent: November 17, 2015
    Assignee: Nalco Company
