Additional Stream Properties

HCURVE Additional Stream Properties

In addition to the default properties that the heating/cooling curve module generates for various process and internal streams, you can request additional stream property information to be reported if desired. The additional properties are calculated at every point where the flash calculation is performed, for all the requested curves, with the existing pressure, temperature and enthalpy conditions.

Usage

On the Heating/Cooling Curve Main Window, click the Additional Stream Properties button. HCURVE Additional Stream Property window appears.

Select the required additional stream properties by selecting the appropriate options. The following table gives a list of properties that will be reported for different stream phases when they are selected:

Additional Property	Total Stream	Vapor Phase	Liquid Phase	L1 Phase	L2/Decant Water Phase
Molecular Weight		X	X	X	X
Actual Density		X	X	X	X
Volumetric Flowrate		X
Compressibility Factor		X
Specific Gravity			X
Flowing Entropy		X
Enthalpy		X	X	X	X
Latent Heat (for points in two phase region)		X
Heat Capacity			X	X	X
Transport Properties
Viscosity		X	X	X	X
Thermal Conductivity		X	X	X	X
Surface Tension			X	X	X
Critical Properties
Temperature		X	X	X	X
Pressure		X	X	X	X
Compressibility Factor		X	X
API Gravity		X	X
Watson K		X	X
Molar Normal Boiling Pt.		X	X

L1-L2 properties will be calculated only when VLLE thermo is present and LLE phase split is possible. VLWE properties will be calculated only when both VLWE thermo and decant water are present.
