Latest Patents

Johnson's latest patents reflect his expertise in chemical engineering and agriculture. One of his notable inventions is an apparatus for removing vanadium from phosphoric acid. This invention includes a precipitator that processes vanadium-containing phosphoric acid by adding an oxidant, which leads to the formation of precipitates containing both phosphorus and vanadium. The solid precipitate is subsequently filtered out, allowing for the production of phosphoric acid with reduced vanadium content. A key aspect of this process is the recycling of the phosphoric acid, ensuring a sustainable approach to chemical processing.

In addition, Johnson has developed a process for the granulation of fertilizer materials. This method utilizes urea phosphate as a granulating agent to help unify finely divided solid particles into consistently sized granules. By dissolving urea in phosphoric acid, urea phosphate is created and coated onto fertilizer materials, facilitating the agglomeration of the particles. This innovative process enhances the efficiency of fertilizer production, offering a beneficial advancement in agricultural practices.
