Abstract: This paper describes the modeling methods of normal functioning of a system of continuous distillation with variable working point of methylcyclohexane from a binary mixture (toluene / methylcyclohexane) using techniques of artificial Intelligence. Initially; the learning basis of the neural network was composed of 577 samples. In a second step; the weights and biases are determined by using the Levenberg Marquardt algorithm. Once the architecture; weights and biases of the neural network were established; it was necessary to know if the neural model is likely to be widespread. The validation of the neural architecture [7-14-1] is therefore to assess its ability to predict the temperature at the column head using the weights and biases calculated during learning; and apply them to another database tests basis composed of 384 data samples. The model of artificial neural network MLP-type [7-14-1] gave a factor of success for the testing and validation phase of 81.9 %. A comparative study was established between the neural model MLP type and classical statistical models; i. e. the total multiple linear regression.
