# Industrial Specification: Venturi Scrubber

## 1. Technical Definition
A wet scrubber that uses the Venturi effect to remove particulate matter and gaseous pollutants from industrial exhaust streams.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.5-2.5 bar differential pressure, 15-85°C liquid temperature, 10-100 m/s throat velocity**. Failure boundary: **Throat velocity exceeding 120 m/s causes liquid film rupture, differential pressure below 0.3 bar reduces collection efficiency to &lt;85%, liquid pH outside 6.5-8.5 range accelerates corrosion**, Mechanism: **Venturi effect breakdown at low velocities (&lt;10 m/s) due to insufficient pressure drop for droplet atomization; cavitation erosion at throat velocities &gt;120 m/s where local pressure drops below liquid vapor pressure; chemical corrosion when scrubbing liquid pH deviates from neutral range**.

### 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.

### 2.2 FMEA (Failure Mode & Effects Analysis)
| Event Trigger | Severity | Failure Mode | Mitigation Strategy |
| :--- | :--- | :--- | :--- |
| Particulate loading exceeding 50 g/m³ at throat inlet | 8 | Throat erosion rate exceeding 0.5 mm/year, leading to geometry distortion | Install pre-filter cyclone for particles &gt;10 μm, implement real-time pressure monitoring with automatic bypass at 2.8 bar ΔP |
| Liquid-to-gas ratio falling below 0.5 L/m³ for more than 30 seconds | 8 | Droplet size increases to &gt;200 μm, reducing collection efficiency below 90% for particles &lt;2.5 μm | Dual redundant metering pumps with flow verification sensors, automatic system shutdown at L/G ratio &lt;0.4 L/m³ |

- **Caution**: 

### Q: What materials are best for Venturi scrubbers in chemical manufacturing?
**A**: For chemical applications, 316L stainless steel offers excellent corrosion resistance, while FRP and polypropylene provide cost-effective alternatives for less aggressive environments. Rubber-lined carbon steel is suitable for abrasive particulate streams.

### Q: How does the Venturi effect improve scrubber efficiency?
**A**: The Venturi throat accelerates gas flow, creating high turbulence that breaks liquid into fine droplets, maximizing contact between pollutants and scrubbing liquid for superior particulate and gas removal efficiency.

### Q: What maintenance do Venturi scrubbers require in chemical plants?
**A**: Regular inspection of liquid injection nozzles for clogging, monitoring throat wear in abrasive applications, and checking material integrity against chemical corrosion are key maintenance tasks for reliable operation.
