Modeling the hydrogen solubility in methanol,ethanol, 1-propanol and 1-butanol

Modeling hydrogen solubility in primary normal alcohols (methanol, ethanol, 1-propanol and 1-butanol) has been studied in this article. Equations of state (EOS), simple correlations and Artificial Neural Networks (ANN) have been compared to find the best modeling technique. Utilizing an equation of state requires an iterative calculation procedure and optimized interaction parameters. Iterative calculation is not suitable when time is important and optimized interaction parameters are not always available. In addition, selection of proper equation of state and mixing rules are serious problems. Simple correlations can be applied to avoid iterative calculations but they have limited flexibility.
