Constructor Details

SystemPCSAFT

public SystemPCSAFT()

Constructor for SystemPCSAFT.

SystemPCSAFT

public SystemPCSAFT(double T,
 double P)

Method Details

addTBPfraction

public void addTBPfraction(String componentName2,
 double numberOfMoles,
 double molarMass,
 double density)

Add a true boiling point (TBP) fraction.

The density parameter is the specific gravity (relative density) of the fraction, which numerically equals the density in g/cm3. Typical values for petroleum fractions range from 0.65 (light naphtha) to about 1.1 (heavy residues). If a value greater than 1.5 is supplied (e.g. 738.0), it is assumed to be density in kg/m3 and is automatically converted by dividing by 1000.

Specified by:

addTBPfraction in interface SystemInterface

Overrides:

addTBPfraction in class SystemThermo

Parameters:

componentName2 - selected name of the component to be added

numberOfMoles - number of moles to be added

molarMass - molar mass of the component in kg/mol

density - specific gravity (relative density) of the component, i.e. density in g/cm3. Typical range: 0.65 to 1.1. Values above 1.5 are auto-converted from kg/m3.

clone

public SystemPCSAFT clone()

clone.

Specified by:

clone in interface SystemInterface

Overrides:

clone in class SystemSrkEos

Returns:

a SystemInterface object

commonInitialization

public void commonInitialization()
