## Description

This MCP server provides specialized engineering tools for designing Vacuum Distillation Units (VDU). It allows engineers to calculate critical column parameters such as diameter using `calculate_column_geometry`, determine required separation levels with `estimate_separation_stages`, and evaluate thermodynamic conditions via `analyze_flash_zone`. Additionally, users can predict mass distribution between VGO and vacuum residue using `predict_product_yields`. It is designed to help optimize vacuum distillation processes by managing residue rates, vacuum pressures, and product specifications.

## Tools

### analyze_flash_zone
Evaluates the thermodynamic conditions at the point of feed entry

### calculate_column_geometry
Determines the physical size of the column needed to handle the vapor load

### estimate_separation_stages
Calculates the number of theoretical stages required to meet product specifications

### predict_product_yields
Predicts the mass distribution between VGO and Vacuum Residue

## Frequently Asked Questions

**How do I calculate the column diameter?**
You can use the `calculate_column_geometry` tool by providing the residue rate, vacuum pressure, and vapor density.

**Can I predict the VGO yield?**
Yes, the `predict_product_yields` tool calculates the mass distribution between VGO and vacuum residue based on your target cut point.

**How many stages are needed for a specific purity?**
Use the `estimate_separation_stages` tool with the required product purity and relative volatility to find the theoretical and actual stages.
