A statistical method for evaluation of the experimental phase equilibrium data of simple clathrate hydrates

摘要: We, herein, present a statistical method for diagnostics of the outliers in phase equilibrium data (dissociation data) simple clathrate hydrates. The applied algorithm is performed on basis Leverage mathematical approach, which Hat matrix, Williams Plot, and residuals selected correlation results lead to define probable outliers. This not only contributes but also identifies range applicability model quality existing experimental data. available literature exponential form used represent/predict hydrate dissociation pressures three-phase conditions (liquid water/ice–vapor-hydrate). investigated formers are methane, ethane, propane, carbon dioxide, nitrogen, hydrogen sulfide. It interpreted from obtained that calculation/estimation behavior systems statistically valid correct, 5 found be doubtful ones 10 points out domain correlation.
