With a total of 2 patents to his name, Lewis has demonstrated a commitment to advancing industrial processes.

Latest Patents

One of his latest patents focuses on a two-stage continuous crystallization process for the production of urea phosphate. This innovative method involves the reaction of impure wet-process orthophosphoric acid, which contains approximately 54 percent P.sub.2 O.sub.5, and urea. The process also includes the simultaneous addition of a selected acidifying agent, such as sulfuric acid, hydrochloric acid, or phosphoric acid, to the clarified mother liquor used as a recycle in the process. The addition of the acidifying agent effectively decreases the pH during crystallization, which increases the solubility of a contaminating water-insoluble iron phosphate-urea salt. As a result, the purity of the crystalline urea phosphate product is significantly improved, and the useful storage life of the recycle mother liquor is prolonged.
