# Industrial Specification: Vacuum/Pressure System

## 1. Technical Definition
A system that creates and maintains controlled vacuum or pressure conditions within a crystallization vessel to facilitate chemical crystallization processes.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.001-10 bar absolute (vacuum: 0.001-1 bar, pressure: 1-10 bar)**. Failure boundary: **Vacuum: 0.0001 bar absolute (cavitation threshold), Pressure: 12 bar absolute (material yield strength limit)**, Mechanism: **Vacuum failure: Cavitation at vapor pressure of process fluid (e.g., water at 0.006 bar at 0°C). Pressure failure: Exceeding yield strength of 316L stainless steel (205 MPa at 20°C) at vessel wall thickness of 10 mm.**.

### 2.1 Analytical Physics Model
Governed by the **Thin-Wall Pressure Vessel Stress Analysis**:

> **Primary Equation**: $\sigma_h = \frac{P \cdot D}{2t}$  
> **Engineering Impact**: Determines the hoop stress boundary to prevent rupture.

| Symbol | Variable Definition | Localized Reference |
| :--- | :--- | :--- |
| P | Internal Pressure | Engineering Constant |
| D | Diameter | Engineering Constant |
| t | Wall Thickness | Engineering Constant |

### 2.2 FMEA (Failure Mode & Effects Analysis)
| Event Trigger | Severity | Failure Mode | Mitigation Strategy |
| :--- | :--- | :--- | :--- |
| Seal degradation due to chemical attack from 5% HCl solution at 80°C | 8 | Vacuum leak rate exceeding 0.1 mbar·L/s, system unable to maintain 0.01 bar absolute | PTFE-coated double mechanical seals with secondary containment and leak detection sensors |
| Condensate accumulation in vacuum pump oil reducing vapor handling capacity | 8 | Pump ultimate vacuum degraded from 0.001 bar to 0.01 bar absolute, extended pump-down time | Gas ballast valve with automatic moisture sensing and oil temperature control at 80±5°C |
