خلاصه مقاله:
In recent years, there has been an increase of interest in the flow of gas at relatively high pressures and temperatures. The energy losses calculations in the flow of gases in conduits, as well as through the porous media constituting natural petroleum reservoirs, requires knowledge of theviscosity of the fluid at the pressure and temperature involved. This work presents a new empirical correlation for calculating viscosity of natural gas mixtures. The empirical modelderived from 2870 experimental data of viscosity at different temperatures and pressures. Also the model can predict viscosity of natural gas accurately for variety ranges pseudo reduced pressure from 0.01 to 21 and pseudo reduced temperatures from 1 to 3. The accuracy of the new model iscompared to mostly used empirical models used in this work. The results showed that the new empirical correlation has 0.88% of average absulte relative deviation percent (AARD%) relative to experimental data. The comparison indicates the superiority of the new method in simplicity and low deviation relative to other methods used in this work for calculating of natural gas viscosity
