| Abstract: | The vapor-liquid phase equilibrium data of binary system of ethanol-cyclohexane has been correlated and predicted by means of BP neural network.In addition,a comparative study between the correlation of three parame-ter NRTL equation counteracting and the predicted result has been made.The result shows that BP neural network is obviously superior to NRTL equation in terms of accuracy. |
