Measurement and prediction of dew points of six natural gases
Dew point measurements for six natural gases, originating from different gas fields of the Norwegian Continental Shelf, were performed using a custom made chilled mirror apparatus. The natural gas samples were taken from different points of the Norwegian pipeline network and their composition was determined by gas chromatography. The experimental dew point data diver a temperature range from 259 to 297 K and a pressure range from 12 to 110 bar. The performance of SRK, PR, PC-SAFT and UMR-PRU models has been evaluated against the experimental data. The results indicate that the best model for hydrocarbon dew point predictions, especially at high pressures and the cricondenbar pressure, is the UMR-PRU model. (C) 2015 Elsevier B.V.
