Thermodynamic Model Selector Skill

Purpose

The Thermodynamic Model Selector Skill guides selection of appropriate thermodynamic property methods based on component characteristics, operating conditions, and accuracy requirements.

Capabilities

• Component analysis (polarity, association, electrolytes)
• Operating condition assessment
• Property method recommendation
• Binary interaction parameter fitting
• VLE/LLE data regression
• Model validation against experimental data
