# Industrial Specification: Scrubber Unit

## 1. Technical Definition
A pollution control device that removes pollutants from industrial exhaust gases through contact with a scrubbing liquid.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.5-2.0 bar differential pressure across packing, 20-80°C liquid temperature, 0.1-5.0 m/s gas velocity**. Failure boundary: **Liquid-to-gas ratio falls below 1.5 L/m³, pH drops below 4.0 or exceeds 9.0, packing pressure drop exceeds 2.5 bar**, Mechanism: **Acid gas absorption failure due to Henry's law equilibrium shift (H₂S K_H=0.102 mol/L·bar at 25°C), liquid film breakdown at Reynolds number &lt;2000, packing flooding at F-factor &gt;2.5 Pa^0.5**.

### 2.1 Analytical Physics Model
Governed by the **Hansen Solubility Distance (HSP)**:

> **Primary Equation**: $R_a = \sqrt{4\Delta\delta_d^2 + \Delta\delta_p^2 + \Delta\delta_h^2}$  
> **Engineering Impact**: Predicts seal/gasket swelling when exposed to CIP chemicals.

| Symbol | Variable Definition | Localized Reference |
| :--- | :--- | :--- |
| \delta_d | Dispersive | Engineering Constant |
| \delta_p | Polar | Engineering Constant |
| \delta_h | Hydrogen | Engineering Constant |

### 2.2 FMEA (Failure Mode & Effects Analysis)
| Event Trigger | Severity | Failure Mode | Mitigation Strategy |
| :--- | :--- | :--- | :--- |
| CaCO₃ scaling formation exceeding 3 mm thickness on packing surfaces | 8 | Gas channeling with 40% reduction in mass transfer coefficient | Integrated ultrasonic scaling prevention system operating at 25 kHz with automatic citric acid injection at pH&lt;6.2 |
| Mist eliminator mesh clogging at 85% porosity reduction | 8 | Liquid carryover exceeding 0.1 g/Nm³ in exhaust stream | Dual-stage demister with 150 μm primary mesh and 50 μm secondary mesh, automated high-pressure (40 bar) spray cleaning every 8 hours |

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

### Q: What materials are available for scrubber unit construction in chemical applications?
**A**: Our scrubber units are constructed from corrosion-resistant materials including stainless steel for high-temperature applications, fiberglass reinforced plastic (FRP) for chemical resistance, and polypropylene for cost-effective acidic gas treatment.

### Q: How does the scrubber unit remove pollutants from chemical plant exhaust gases?
**A**: The scrubber unit uses a liquid distribution system to spray scrubbing solution through packing media, creating maximum contact between exhaust gases and liquid to absorb pollutants, with mist eliminators preventing liquid carryover.

### Q: What maintenance is required for the scrubber unit's spray nozzles and packing media?
**A**: Regular inspection of spray nozzles for clogging and packing media for fouling is recommended, with cleaning or replacement based on operating conditions and the specific pollutants being removed from your chemical process exhaust.
