Class TBPfractionModel.LeeKesler

java.lang.Object

neqsim.thermo.characterization.TBPfractionModel.TBPBaseModel

neqsim.thermo.characterization.TBPfractionModel.LeeKesler

All Implemented Interfaces:

Serializable, Cloneable, TBPModelInterface

Enclosing class:

TBPfractionModel

public class TBPfractionModel.LeeKesler
extends TBPfractionModel.TBPBaseModel

Lee-Kesler property estimation method.

The Lee-Kesler (1976) correlations use boiling point and specific gravity as primary inputs to estimate critical properties. This model is particularly useful when Watson characterization factor data is available.

Correlations:

• Tc = 341.7 + 811·SG + (0.4244 + 0.1174·SG)·Tb + (0.4669 - 3.2623·SG)·10⁵/Tb
• ln(Pc) = 8.3634 - 0.0566/SG - f(Tb, SG)
• ω from Kesler-Lee correlation (different for Tbr < 0.8 and Tbr ≥ 0.8)
