Title: The Innovations of Sergio Ortega Pierres
Introduction
Sergio Ortega Pierres is a notable inventor based in Mexico City, MX. He has made significant contributions to the field of chemical engineering, particularly in the stabilization of phosphoric acid and the production of ammonium polyphosphate fertilizers. With a total of 2 patents, his work has had a meaningful impact on agricultural chemistry.
Latest Patents
One of his latest patents is focused on the stabilization of wet-process phosphoric acid. This innovation involves adding an inorganic oxidizing agent and silica to impure wet-process phosphoric acid to prevent sludge formation. The treated solution is then concentrated to a P.sub.2 O.sub.5 content of 35% to 42% by weight, allowing for the separation of a solid phase and a substantially solid-free liquid phase of phosphoric acid, which is improved in stability.
Another significant patent by Ortega Pierres is the process for making stable sludge-free ammonium polyphosphate fertilizer. This process entails introducing ammonia and a blend of impure wet-process phosphoric acid into a reactor. The mixed reactants are retained for a brief period before being quenched, resulting in a solution that undergoes aging to precipitate and nucleate suspended insoluble metallic phosphates and organic matter.
