Description
In this work, the Least Squares Support Vector Machine (LSSVM) algorithm is employed to present several numerical models for calculation/estimation of the clathrate hydrate dissociation conditions of methane, carbon dioxide, nitrogen, and hydrogen in the presence of 3 most-widely used water " soluble" organic promoters including tetrahydrofuran (THF), 1,4-dioxane, and acetone. The Hybrid Genetic Algorithm (H-GA) is applied to obtain the optimal models parameters. The final results indicate the accuracy and reliability of the proposed models with the absolute average relative deviations (AARD) of generally less than 10% and squared correlation coefficients of generally greater than 0.99. It was found that the models contribute to high deviations for the representations/predictions of the N 2+THF, CH 4+1,4-dioxane, and H 2+acetone clathrate hydrates phase equilibria. © 2011 Elsevier B.V.
