# Industrial Specification: Solution Storage Tank

## 1. Technical Definition
A tank designed to store chemical solutions as part of a recirculation system.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.1-2.0 bar (gauge pressure), 5-40°C, 0-95% fill capacity**. Failure boundary: **Yield stress of 316L stainless steel at 250 MPa, buckling pressure at 3.5 bar, brittle fracture below -20°C**, Mechanism: **Stress corrosion cracking from chloride ions at &gt;60°C, hydrogen embrittlement from cathodic protection over-polarization, fatigue failure from &gt;10^6 pressure cycles at &gt;1.5 bar amplitude**.

### 2.1 Analytical Physics Model
Governed by the **Thin-Wall Pressure Vessel Stress Analysis**:

> **Primary Equation**: $\sigma_h = \frac{P \cdot D}{2t}$  
> **Engineering Impact**: Determines the hoop stress boundary to prevent rupture.

| Symbol | Variable Definition | Localized Reference |
| :--- | :--- | :--- |
| P | Internal Pressure | Engineering Constant |
| D | Diameter | Engineering Constant |
| t | Wall Thickness | Engineering Constant |

### 2.2 FMEA (Failure Mode & Effects Analysis)
| Event Trigger | Severity | Failure Mode | Mitigation Strategy |
| :--- | :--- | :--- | :--- |
| Chloride concentration exceeding 25 ppm at &gt;60°C | 8 | Stress corrosion cracking initiating at weld heat-affected zones | Duplex stainless steel (2205) construction with post-weld heat treatment at 1050°C for 30 minutes |
| Thermal cycling between 5°C and 40°C at &gt;3 cycles/hour | 8 | Low-cycle fatigue at nozzle-to-shell junctions exceeding 0.2% strain amplitude | Reinforcing pads with 2:1 elliptical cutouts and radius-to-thickness ratio &gt;10 at all penetrations |

- **Caution**: 

### Q: What materials are best for storing aggressive chemical solutions?
**A**: Stainless Steel 316L offers excellent corrosion resistance for most chemicals, polypropylene handles acids and bases well, and Fiberglass Reinforced Plastic (FRP) provides durability against corrosive environments at lower temperatures.

### Q: How does the agitator improve solution storage in recirculation systems?
**A**: The agitator prevents sedimentation and maintains uniform solution concentration by continuously mixing the chemical, ensuring consistent quality and preventing solids from settling at the bottom of the tank.

### Q: What safety features should a chemical solution storage tank include?
**A**: Essential safety features include a secure manhole for safe access, properly sized inlet/outlet nozzles to prevent overpressure, and a reliable level sensor to monitor solution volume and prevent overfilling or dry running.
