【Abstract】 The dynamic simulation models for batch reaction processes are developed on the base of kinetics models for condensation reaction developed by rigorous method in the paper. Furthermore, the CSTR is used to conduct the calculations of the mass balance, energy balance and phase equilibrium by means of Eular method. In the phase equilibrium calculation, a constant volume model, which uses two-layer approach to determine the parameters of phase equilibrium, is introduced. Therefore it can not only guarantee the accuracy and stability, but also meet the requirement of the simulation speed. The result of simulation is satisfactory.更多还原
