| Summary: | The focus of this work is on the behavior of hydrocarbon gas viscosity and gas density. The viscosity of hydrocarbon gases is a function of pressure, temperature, density, and molecular weight, while the gas density is a function of pressure, temperature, and molecular weight. This work presents new approaches for the prediction of gas viscosity and gas density for hydrocarbon gases over practical ranges of pressure, temperature and composition. These correlations can be used for any hydrocarbon gas production or transportation operations. In this work we created a large database of measured gas viscosity and gas density. This database was used to evaluate existing models for gas viscosity and gas density. From the work performed in this thesis we provide new models for gas density and gas viscosity, as well as optimization of existing models using our new database. The objectives of this research are: To create a large-scale database of measured gas viscosity and gas density data. This database will contain all of the information necessary to determine the applicability of various models for gas density and gas viscosity over a wide range of pressures and temperatures. To evaluate a number of existing models for gas viscosity and gas density. To develop new models for gas viscosity and gas density using our research database - these models will be proposed and validated. We created a large database for this study. A total of 13,656 data points were used for this study, these data points have properties such as composition, viscosity, density, temperature, pressure, pseudoreduced properties and gas compressibility factor. We used this database to evaluate the applicability of the exis-ting models to determine hydrocarbon gas viscosity, and hydrocarbon gas density (or more specifically, the gas z-factor). Finally, we developed new models/calculation approaches to determine hydrocarbon gas viscosity and also provided an optimization of the existing equations-of-state (EOS) for the calculation of the gas compressibility factor. |
