Abstract

In this study, the simulation model for the decomposition section of the urea plant was developed by using Aspen Plus. The decomposition reaction in the physical equipments such as heat exchanger, separator and stripper was handled with the use of the combination of the equilibrium reactors and built-in physical equipments in Aspen Plus. The thermodynamic model SR-Polar was used for the estimation of phase and chemical equilibria, density and other thermodynamic properties of the system. The results of the simulation were compared with the existing plant data and a good agreement was observed. Effects of the important parameters such as temperature, pressure and CO2 VWULSQJDHPRÀZKOTXGEQ separator were also discussed in the decomposition section of urea plant.
