Fluid Critical Point Modules

Calculate gas compressibility factor or Z factor from the cubic equation (Poling).

The compressibility factor is used to account for the non ideal behaviour of real gases. The non ideal gas law is expressed as

`P V = Z Ro T `

where :

P = gas pressure
T = gas temperature
V = gas mole volume
Z = gas compressibility factor
Ro = universal gas constant

The compressibility factor can be calculated using either the Peng Robinson, Soave, Redlich Kwong or Van Der Waals cubic equations of state (EOS). The gas data is taken from Poling.

Calculate gas density from critical pressure, critical temperature and acentric factor data for organic and inorganic fluids (Yaws).

The compressibility factor can be calculated from either the Peng Robinson, Soave, Redlich Kwong, or van der Waals cubic equation. The compressibility factor calculation is valid for gas phase only. The gas specific gravity is approximately equal to the ratio of the gas molar mass over the molar mass of air (28.964 g/mol).
