Title: Josiah S Lewis, Jr: Innovator in Fertilizer Production
Introduction
Josiah S Lewis, Jr. is a notable inventor based in Florence, AL (US). He has made significant contributions to the field of fertilizer production through his innovative processes. His work focuses on the efficient production of granular ammonium phosphate sulfate and monoammonium phosphate.
Latest Patents
Lewis holds a patent for a process that utilizes phosphoric and sulfuric acids, liquid anhydrous ammonia, and water to produce fertilizers. The ammonia is premixed with a small quantity of water in a common pipe. This mixture is then combined downstream with the acids introduced through a pipe cross. The acids and aqua ammonia react within the pipe cross and the extension of the pipe, which measures 7 feet in length and is cooled by a water jacket. In an alternative variation, the cooling water jacket is omitted, and the reaction tube is constructed from either Hastelloy C metal or Teflon-lined mild steel pipe. The slurry produced from the reactor is granulated with recycle fines, additional phosphoric and sulfuric acids, and ammonia in a rotary drum. The final product is cooled and screened for size removal. This uncomplicated and cost-effective equipment has successfully produced various grades of ammonium phosphate sulfate and monoammonium phosphate.
