# 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
- Uncertainty quantification

## Usage Guidelines

### When to Use

- Fitting interaction parameters
- Validating thermodynamic models
- Assessing model uncertainty

### Prerequisites
- Component list defined
- Operating ranges specified
- Experimental data available
- Accuracy requirements known

### Best Practices
- Consider all phase equilibria
- Validate with experimental data
- Document model selection rationale
- Assess sensitivity to parameters

## Process Integration

This skill integrates with:
- Process Simulation Model Development
- Distillation Column Design
- Crystallization Process Design
