Neural networks for predicting mass transfer parameters in supercritical extraction

Abstract: Neural networks have been investigated for predicting mass transfer coefficients from supercritical Carbon Dioxide/Ethanol/Water system. To avoid the difficulties associated with reduce experimental data set available for supercritical extraction in question, it was chosen to use a technique to generate new semi-empirical data. It combines experimental mass transfer coefficient with those obtained from correlation available in literature, producing an extended data set enough for efficient neural network ident… Show more

“…These models are assessed using cross validation, which leverages the available data for both the construction and validation of the predictive models. Fonseca et al 2000, investigated the use of neural networks for predicting mass transfer coefficients from supercritical Carbon Dioxide/Ethanol/Water system. They used a technique which combines experimental mass transfer coefficient with those obtained from correlations available in literature to generate new semi-empirical data for the network training.…”
