| Abstract: | Correlation and representation of the excess Gibbs energy(GEm) with the temperature(T),pressure(p),composition(x) and activity coefficient(γ) of a system by using neural network have been studied in this paper.Predictions of the excess Gibbs energy based on the trained neural network models have been compared with experiments.The inaccuracy of the predictions was lower than 1.42%. |

| Keywords: | excess Gibbs energy neural network correlation parameter of free energy |
