| Abstract: | Based on the Edwards′ thermodynamic model,the program of simulation calculation has been developed for NH 3 CO 2 H 2O solution.The comparison with literature data reveals a good agreement.This program has been applied for calculating the phase equilibrium of the condensers in the urea process successfully.The calculated results agreed well with the design values. |
