WebJun 2, 2015 · Calculating properties of natural gas Find the density, formation volume factor (FVF), viscosity, and isothermal compressibility of a gas with the following properties and conditions: γg = 0.7 H 2 S = 7% CO 2 = 10% p = 2,010 psia T = 75°F. Solution The density is calculated from Eq. 3 in Gas formation volume factor and density : Now, the molecular weight of gas is 28.87 lb/lb-mole: γ g = M W g 28.97 Equation 3.72b Real Gas Viscosity, μg. The viscosity of natural gases can be determined by the correlation of Lee, Gonzalez, and Eakin [14]: μ g = 1.0 × 10 − 4 K e X ρ g Y Equation 3.73 with K = ( 9.379 + 0.01607 M W g) T 1.5 209.2 + 19.26 M W g … See more The gas supercompresibility factor, Z (or Z-Factor, or Real Gas Deviation Factor), is a function of pressure and temperature that corrects the Ideal … See more The isothermal compressibility of a real gas can also be determined directly from the Real Gas Law. Starting with the definition of isothermal compressibility: Substituting the Real Gas Law, Equation 3.27, into Equation … See more The Formation Volume Factor, Bg, of a real gas, like its oil phase analog, is used to convert one standard cubic foot, SCF, of gas at reference conditions to its volume at reservoir conditions. For natural gases, in the U.S. domestic … See more The density of a real gas can also be determined directly from the Real Gas Law. Starting with the Real Gas Law: pV=ZnRT Now the number of moles is equal to a mass divided by the molecular weight, n = m / MWg. … See more scottish celtic paganism
