Title: The Innovations of Thomas A. Edwards

Introduction

Thomas A. Edwards is a notable inventor based in Lakeland, Florida, recognized for his contributions to the field of chemical engineering. He holds a patent for a unique method of producing ammonium polyphosphate solutions, which has significant implications for agricultural applications.

Latest Patents

Edwards' patent focuses on the production of ammonium polyphosphate solutions. This innovative process involves using a pipe reactor where ammonia is injected countercurrent to superphosphoric acid. The method promotes vigorous backmixing of the reactants, resulting in a melt of ammonium polyphosphate. To prevent the formation of insoluble scale within the reactor, the sidewalls are cooled to form a layer of ammonium polyphosphate melt. The final product solution is achieved by dissolving the melt in recycled aqueous ammonium polyphosphate and further diluting it with water. Additionally, the process may include minor amounts of urea to enhance stability and conversion.
