Latest Patents

Hiroyuki Nishikawa holds a patent for a process titled "Process for concurrently treating process waste waters and flue gases." This process involves stripping ammonium nitrogens and organic materials from waste waters, which are discharged from plants that manufacture gases for ammonia synthesis. The method includes selectively decomposing organic materials in the presence of a catalyst at temperatures ranging from 120°C to 400°C. The remaining gases are then mixed with flue gases to create a gaseous mixture containing ammonia, which is reacted over a catalyst at temperatures between 150°C and 700°C. This innovative process effectively oxidizes any unreacted ammonia, rendering harmful substances innocuous.
