All Implemented Interfaces:

Serializable, Cloneable, SystemInterface

public class SystemPitzer
extends SystemEos

Thermodynamic system using the Pitzer GE model for the aqueous phase and SRK EOS for gas and optional oil phases.

Supports vapor-liquid-liquid equilibrium (VLLE): gas (SRK), oil (SRK), aqueous (Pitzer). Enable VLLE by calling setMultiPhaseCheck(true) before running the flash.

Constructor Details

SystemPitzer

public SystemPitzer()

Default constructor.

SystemPitzer

public SystemPitzer(double T,
 double P)

Constructor for SystemPitzer.

Parameters:

T - temperature in K

P - pressure in bara

SystemPitzer

public SystemPitzer(double T,
 double P,
 boolean checkForSolids)

Constructor for SystemPitzer.

Parameters:

T - temperature in K

P - pressure in bara

checkForSolids - include solid phase

Method Details

setMultiPhaseCheck

public void setMultiPhaseCheck(boolean multiPhaseCheck)

method to specify if calculations should check for more than two fluid phases.

Overridden to create a SRK EOS oil phase (not a Pitzer clone) when enabling multi-phase (VLLE) checks. Phase layout: [0]=SRK(gas), [1]=Pitzer(aqueous), [2]=SRK(oil).

Specified by:

setMultiPhaseCheck in interface SystemInterface

Overrides:

setMultiPhaseCheck in class SystemThermo

Parameters:

multiPhaseCheck - Specify if the calculations should check for more than two fluid phases. Default is two fluid phases (gas and liquid). If set to true the program will check for gas and multiple liquid phases (eg. gas-oil-aqueous).

setMixingRule

public void setMixingRule(String typename)

method to set the mixing rule for the fluid.

Parameters:

typename - a String object

clone

public SystemPitzer clone()

clone.

Specified by:

clone in interface SystemInterface

Overrides:

clone in class SystemThermo

Returns:

a SystemInterface object
