# Industrial Specification: Reagent Storage Tank

## 1. Technical Definition
A sealed container designed for the safe storage and containment of chemical reagents within an industrial system.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.1-2.0 bar internal pressure, -10°C to 40°C ambient temperature, 0-95% relative humidity**. Failure boundary: **3.5 bar internal pressure (yield strength threshold), -20°C (brittle fracture temperature), 150°C (polymer seal degradation)**, Mechanism: **Von Mises yield criterion exceeding 250 MPa stress at 3.5 bar pressure, glass transition temperature of polypropylene seals at -20°C, Arrhenius degradation kinetics of EPDM seals above 150°C**.

### 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 |
| :--- | :--- | :--- | :--- |
| Hydrogen embrittlement from 50 ppm H2S contamination in stored reagent | 8 | Intergranular cracking in 316L stainless steel tank walls | Duplex stainless steel (2205) construction with 22% chromium minimum |
| Thermal cycling between -5°C and 35°C at 2 cycles/hour | 8 | Low-cycle fatigue cracking at welded nozzle junctions | Finite element analysis-optimized reinforcement pads with 3:1 taper ratio |

- **Caution**: 

### Q: What materials are recommended for corrosive reagent storage?
**A**: For corrosive chemicals, 316L stainless steel offers excellent corrosion resistance, while HDPE is ideal for acids and solvents where chemical compatibility is required.

### Q: How does the pressure relief valve enhance safety?
**A**: The pressure relief valve automatically releases excess pressure to prevent tank rupture, maintaining safe operating conditions during temperature fluctuations or chemical reactions.

### Q: What maintenance is required for reagent storage tanks?
**A**: Regular inspection of seals, valves, and sensors; cleaning between reagent changes; and pressure testing according to industry standards ensure long-term reliability and safety.
