SRK-Peneloux Density Method

Use the following correlation to calculate the Peneloux Volume Shift for Hydro Carbons.

 

Where,

c1 = 2.9056e - 01, c2 = 8.775e - 02

c3 = 0.40768, c4 = 0.29441

 

Tci

=

Critical Temperature for component i, K

Pci

=

Critical Pressure for component i, Kpa

wi

=

Acentric Factor for component i

xi

=

Mole Fraction of component i

N

=

Total number of components

Vs

=

Peneloux Volume Shift, m3/Kmol

 

Use the following correlation to calculate the Peneloux Volume Shift for water.

 

 

A1 = 3.73625

A2 = -2.70717

A3 = 0.642567

 

Calculate Peneloux Density by using the Peneloux Volume Shift, and the Compressibility and Density values obtained from the SRK method.

 

 

Here, Z and Vmix are calculated using the SRK method.

T, P = Temperature and Pressure of the system.

R = Universal Gas Constant.

 

Note: There are special parameters used for polar components.
