## Description

This MCP server provides specialized engineering tools for designing pressure relief systems in refinery environments. It follows the industry-standard API 520/521 methodology to ensure safety and regulatory compliance. Users can use `calculate_relief_load` to determine mass flow rates for various overpressure scenarios like fire or blocked outlets. The server also includes `size_relief_valve` to calculate required orifice areas, `evaluate_disposal_capacity` to verify flare or vent sufficiency, and `analyze_system_contingency` to assess safety margins between design and operating pressures.

## Tools

### analyze_system_contingency
Determines how much "room for error" exists in the design regarding pressure and flow

### calculate_relief_load
Determines the mass flow rate required for a specific overpressure scenario

### evaluate_disposal_capacity
Checks if the existing disposal system can handle the relief loads from multiple scenarios

### size_relief_valve
Calculates the required orifice area for a relief valve to handle a specific load

## Prompt Examples

**Prompt:** 
```
Calculate the relief load for a fire scenario with a vessel volume of 50m3 and surface area of 25m2.
```

**Response:** 
```
The calculated relief load for the fire scenario is 1250 kg/s with a high criticality rating.
```

**Prompt:** 
```
What is the required orifice area for a relief load of 500 kg/s with a set pressure of 20 bar?
```

**Response:** 
```
The required orifice area is 0.045 m2, which corresponds to a recommended orifice size of 'J'.
```

**Prompt:** 
```
Check the safety margin for a design pressure of 50 bar and operating pressure of 40 bar with a load of 200 kg/s and safety factor of 1.2.
```

**Response:** 
```
The system has a pressure margin of 10 bar and a flow margin of 240 kg/s, resulting in a 'Safe' status.
```

## Frequently Asked Questions

**What standards does this tool follow?**
The tool follows the API 520 and API 521 methodologies for pressure-relieving systems.

**Can I check if my flare system is large enough?**
Yes, you can use the `evaluate_disposal_capacity` tool to compare calculated relief loads against your existing disposal system capacity.

**How do I calculate the required valve size?**
First, determine the load using `calculate_relief_load`, then pass that value into `size_relief_valve` along with fluid and operating properties.
