## 🔎 Thermodynamic Calculations in PyThermoFlash

### 🔵 Bubble-Point Pressure

The bubble-point pressure is the pressure at which the first bubble of vapor forms when heating a liquid mixture at constant temperature. It represents the equilibrium pressure where the liquid starts to vaporize at a given temperature and composition.

### 🔵 Bubble-Point Temperature

The bubble-point temperature is the temperature at which the first bubble of vapor appears when heating a liquid mixture at constant pressure. It marks the onset of vaporization under the specified pressure and composition.

### 🟠 Dew-Point Pressure

The dew-point pressure is the pressure at which the first drop of liquid condenses from a vapor mixture at a constant temperature. It defines the equilibrium pressure where condensation begins at the given temperature and vapor composition.

### 🟠 Dew-Point Temperature

The dew-point temperature is the temperature at which the first droplet of liquid forms when cooling a vapor mixture at constant pressure. It indicates the onset of condensation under the specified pressure and composition.

### ⚡ Isothermal Flash Calculation

The isothermal flash calculation determines the amounts and compositions of the vapor and liquid phases when a mixture partially vaporizes or condenses at a fixed temperature and pressure. This calculation is fundamental in process simulation, as it models phase equilibrium and phase splits for complex mixtures.

## 📚 Thermodynamic Models Supported

PyThermoFlash supports a variety of thermodynamic models to calculate phase equilibria, ranging from ideal to non-ideal mixtures.

### Supported Models:

- **📏 Raoult’s Law**: For ideal mixtures, Raoult’s law is used to calculate the vapor pressure of each component.
- **🔗 NRTL (Non-Random Two-Liquid Model)**: Suitable for non-ideal mixtures, especially those with strong intermolecular interactions.
- **🧪 UNIQUAC (Universal Quasi-Chemical Model)**: Ideal for systems with significant differences in molecular size or polarity.

## 📥 Installation

Install PyThermoFlash via pip:

```bash
pip install PyThermoFlash

import pyThermoFlash as ptf
```

### 🔗 Dependencies

PyThermoFlash depends on the `PyThermoModels` library for thermodynamic calculations. Ensure you have it installed:

Additionally, PyThermoFlash uses `PyThermoDB` as a reference for thermodynamic data. Make sure the required data files are available in your environment.

```bash
pip install PyThermoModels
pip install PyThermoDB
```

## 🧪 Examples

To get started with PyThermoFlash, you can explore the `tests` folder in the project directory. It contains various test scripts and configurations that demonstrate how to use the library for different thermodynamic calculations.
