two new correlations are first presented for calculating the pseudo- critical pressure and temperature of the gas mixture as a function of the gas specific gravity.Then,a simple correlation on the basis of the standard gas compressibility factor chart is introduced for a quick estimation of sweet...
Equation 1.34: Alternative pseudocritical temperature calculation using specific gravity (1.34)TpC=94.72+170.75γ Where: TpC: Pseudocritical temperature (Kelvin) γ: Gas specific gravity (dimensionless) The next step is to calculate the pseudocritical reduced pressure and pseudocritical reduced temperature...

The hydrate formation chart given by Guo and Ghalambor (2005) shows that a natural gas with specific gravity of 0.70 should form gas hydrate at 300 psia and 49°F. Therefore the air flow rate of 4500 scfm should cause ice/hydrate balling problem. If an air flow rate of 3000 scfm is ...
In their work, the California Natural Gas Association method is used to model compressibility as a function of specific gravity and pressure. The sources feeding the transmission network do not necessarily supply gas with equal specific gravity. In their model, they assumed that when different flow...
