# Industrial Specification: Vapor-Liquid Separator

## 1. Technical Definition
A device that separates vapor from liquid phases in a vacuum evaporation system.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.1-1.0 bar absolute pressure, 20-150°C temperature, 0.5-5.0 m/s vapor velocity**. Failure boundary: **Vapor velocity exceeds 6.0 m/s causing entrainment, liquid level drops below 15% of vessel height causing vapor bypass, pressure drop exceeds 0.3 bar causing flooding**, Mechanism: **Droplet entrainment due to excessive vapor velocity exceeding terminal settling velocity (Stokes' law violation), vapor bypass through demister pad due to insufficient liquid seal height, flooding from excessive pressure drop across separation media**.

### 2.1 Analytical Physics Model
Governed by the **Darcy-Weisbach Pressure Drop**:

> **Primary Equation**: $\Delta P = f \cdot \frac{L}{D} \cdot \frac{\rho v^2}{2}$  
> **Engineering Impact**: Critical for sizing CIP (Clean-In-Place) pump heads.

| Symbol | Variable Definition | Localized Reference |
| :--- | :--- | :--- |
| f | Friction Factor | Engineering Constant |
| L | Pipe Length | Engineering Constant |
| v | Velocity | Engineering Constant |

### 2.2 FMEA (Failure Mode & Effects Analysis)
| Event Trigger | Severity | Failure Mode | Mitigation Strategy |
| :--- | :--- | :--- | :--- |
| Demister pad fouling with 0.5 mm particulate accumulation | 8 | Pressure drop increase to 0.4 bar causing liquid carryover | Install dual-stage demister with 150 micron pre-filter and automated backflush system |
| Thermal expansion differential of 2.1 mm between vessel and internals at 150°C | 8 | Internal component misalignment causing 40% separation efficiency loss | Design with Invar 36 alloy internals (CTE 1.2×10⁻⁶/°C) matching carbon steel vessel expansion |

**Downstream Applications**: Concentrated Fruit Juice, Pharmaceutical Intermediates, Desalinated Water  

## 5. Engineering Risks & FAQ
- **Caution**: 
- **Caution**: 
- **Caution**: 

### Q: What materials are used in your vapor-liquid separators?
**A**: Our separators are constructed from corrosion-resistant stainless steel grades 304 and 316L, ensuring durability in demanding industrial environments.

### Q: How does the demister pad work in a vapor-liquid separator?
**A**: The demister pad or mesh captures liquid droplets from the vapor stream through impingement, allowing clean vapor to exit while collected liquid drains back into the separator.

### Q: What industries use vapor-liquid separators in machinery manufacturing?
**A**: These separators are essential in chemical processing, pharmaceutical production, food and beverage manufacturing, and any industry using vacuum evaporation systems for phase separation.
