# Industrial Specification: Gas Cleaning Plant

## 1. Technical Definition
A system for removing impurities from blast furnace gas in steelmaking.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.8-1.2 bar inlet pressure, 0.5-0.8 bar outlet pressure, 150-250°C operating temperature**. Failure boundary: **Inlet pressure &lt;0.5 bar causes flow reversal, outlet pressure &gt;1.5 bar ruptures bag filters, temperature &gt;280°C melts PTFE filter media**, Mechanism: **Pressure differential collapse across venturi scrubbers at ΔP&lt;0.3 bar, thermal degradation of polypropylene demisters above 120°C, sulfuric acid dew point corrosion at 120-150°C with H2S&gt;200 ppm**.

### 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 |
| :--- | :--- | :--- | :--- |
| Cyclic thermal stress from 150-250°C temperature swings during BF gas surges | 8 | Thermal fatigue cracking in quench tower refractory lining | Install silicon carbide refractory with 0.8 W/m·K thermal conductivity and 4.5×10^-6 /°C expansion coefficient |
| Ammonium chloride deposition from NH3&gt;50 ppm and HCl&gt;20 ppm at 120-180°C | 8 | Flow restriction and pressure drop increase to ΔP&gt;1.0 bar across electrostatic precipitator | Maintain gas temperature above 180°C through preheater with 2.5 MW capacity and install soot blowers at 40 bar steam pressure |

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

### Q: What impurities does this gas cleaning plant remove from blast furnace gas?
**A**: Our gas cleaning plant effectively removes particulate matter, dust, moisture, and corrosive elements from blast furnace gas, ensuring cleaner emissions and protecting downstream equipment in steelmaking operations.

### Q: Why is stainless steel used in specific zones of the gas cleaning plant?
**A**: Stainless steel is strategically employed in corrosive zones to withstand harsh chemical environments and high temperatures, enhancing durability and reducing maintenance needs in the gas cleaning process.

### Q: How does the venturi scrubber component improve gas cleaning efficiency?
**A**: The venturi scrubber uses high-velocity gas flow to atomize scrubbing liquid, creating fine droplets that capture fine particulates and contaminants from blast furnace gas with high efficiency.
