The only process simulator fully specialized in the nitric acid manufacturing process.

ProSim Plus HNO3 is a product of the French company Fives ProSim, designed based on over 30 years of experience in modeling and simulating nitric acid plants and nitrous acid vapor absorption systems (mainly referencing Professor Xavier Joulia's 1981 paper "Contribution au développement d’un programme général de simulation – Application à l’analyse du fonctionnement d’un atelier de production d’acide nitrique"). In addition to the standard features of ProSim Plus as a process simulator, it incorporates rigorous models for chemical reactions and mass transfer rates in gas-liquid phases in absorption towers and condensers, as well as oxidation reactions in the gas phase within heat exchangers and piping. Notably, the oxidation reaction from NO to NO2 in the gas phase applies a rate model rather than an equilibrium model.

basic information

• Component database (H2O, NO, NO2, N2O4, N2, O2, HNO3, NH3, N2O, N2O3, HNO2, CO2, CO, CH4, H2) • Strict thermodynamic model for high-concentration nitric acid aqueous solution • Absorption model with mass transfer rate limitation (packed columns, filling, spray columns) • Liquid phase chemical reaction model (hydrolysis of HNO3 and HNO2, decomposition of HNO2) • Gas phase chemical reaction model (kinetic model for the oxidation reaction from NO to NO2, dimerization equilibrium reaction model from NO2 to N2O4, equilibrium reaction model for N2O3 formation, equilibrium reactions in the NOx-H2O-HNO3 system) • Nitrous acid vapor compressor model (isentropic model or polytropic efficiency model)
