# Industrial Specification: Product Collection Tank

## 1. Technical Definition
A storage vessel designed to collect and temporarily hold purified solvent products in an automated solvent recovery and purification system.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.1-2.0 bar gauge pressure, 20-80°C temperature, 50-95% fill level**. Failure boundary: **3.5 bar internal pressure (yield strength threshold), 120°C thermal degradation point, 0% or 100% fill level sensor failure**, Mechanism: **Von Mises yield criterion exceeding 250 MPa at 3.5 bar internal pressure for 316L stainless steel, Arrhenius degradation kinetics above 120°C for polypropylene linings, capacitive level sensor dielectric constant shift at boundary conditions**.

### 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 |
| :--- | :--- | :--- | :--- |
| Pressure relief valve mechanical seizure due to polymer deposition | 8 | Tank overpressure exceeding 3.5 bar causing permanent deformation | Dual redundant pressure relief valves with staggered setpoints (2.8 bar primary, 3.2 bar secondary) and quarterly mechanical cycling protocol |
| Electrochemical corrosion at weld seams from chloride ion concentration exceeding 25 ppm | 8 | Through-wall pitting corrosion leading to solvent leakage at 0.5 mm/year penetration rate | Post-weld electropolishing to Ra 0.4 μm surface finish and cathodic protection system maintaining -0.85 V vs Ag/AgCl reference electrode |
