An assessment test for phase equilibrium data of water soluble and insoluble clathrate hydrate formers

摘要: Abstract In this communication, the validity of experimental data reported in literature for structure II and H hydrate dissociation conditions presence water soluble/insoluble promoters are assessed. Outliers identified using a statistical method. The Leverage mathematical based approach is employed determination Hat matrix, sketching Williams plot, computation residual values (difference between calculated data) specific model. addition, range applicability applied model quality available determined. Because high accuracy least squares support vector machine (LSSVM) method which has been used previous studies, prediction clathrate hydrates methane, carbon dioxide, nitrogen, hydrogen soluble organic (tetrahydrofuran (THF), 1,4-dioxane, acetone) twenty-one insoluble hydrocarbon promoters. It expected that results study would provide better understanding reliability equilibrium data. This enable development more accurate thermodynamic models on reliable
