Title: Innovations in Fertilizer Production by Xavier Rondeau

Introduction

Xavier Rondeau is a notable inventor based in Compiègne, France. He has made significant contributions to the field of fertilizer production, particularly through his innovative methods that enhance the efficiency of urea and ammonium sulfate fertilizers.

Latest Patents

Rondeau holds a patent for a method of producing a fertilizer containing urea and ammonium sulfate. This method involves the production of solid urea ammonium sulfate (UAS) fertilizers from sulfuric acid, ammonia, and urea. The process ensures that free ammonia and/or carbamate, which is decomposed from urea production, reacts with sulfuric acid without substantially decomposing urea in the process stream. After this reaction, urea and ammonium sulfate are mixed and particulated. The integration point of ammonium sulfate production in the urea production process is strategically chosen based on the desired product composition. The reaction occurs in a pipe reactor, where the reactor's head enhances the chemical reaction between sulfuric acid and ammonia, while the urea solution surrounds the formation of ammonium sulfate.
