Technology of highly concentrated NO

Popis výsledku v původním jazyce

The design of concentrated nitric oxide technology based on catalytic oxidation of NH3 by steam-oxygen mixture and the pilot plant unit are presented. The process can be separated into four distinct areas: mixing and preheating of reactants, catalytic oxidation, cooling and steam condensation and gas purification. The reaction mixture is prepared from gaseous NH3, oxygen (ł90 mol. % ) and overheated water vapour. The mixture is cleaned in ceramic or cloth filter and fed to the catalytic reactor. The oxidative reaction of NH3 takes place on Pt-Rh gauzes and hot gas containing NO, O2, N2, H2O and traces of NH3 is cooled with water sprays from 750 - 850 °C to about 150 °C. It is then drawn through a tube counter-current condenser. The apparatuses and their arrangement are designed so that the free volume is minimised and the extent of undesirable reactions of nitric oxide with oxygen was negligible. Output gases from condenser are passed into packed column sprayed with solution of HNO3 wh
