# Industrial Specification: Collection Tank

## 1. Technical Definition
A vessel designed to collect and temporarily store recovered solvents within a solvent recovery system.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.1-2.0 bar gauge pressure, -20°C to 80°C temperature**. Failure boundary: **Yield strength exceeded at 3.5 bar internal pressure or -40°C brittle fracture temperature**, Mechanism: **Plastic deformation from hoop stress exceeding 316L stainless steel yield strength (205 MPa) or brittle fracture below ductile-to-brittle transition temperature**.

### 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 |
| :--- | :--- | :--- | :--- |
| Solvent-water azeotrope formation creating 1.8 bar vapor pressure at 95°C | 8 | Overpressure rupture at welded seam with 0.8 safety factor | Pressure relief valve set at 2.4 bar with ASME Section VIII Div. 1 certification |
| Chlorinated solvent hydrolysis producing 50 ppm hydrochloric acid concentration | 8 | Pitting corrosion at 0.5 mm/year rate exceeding 3 mm wall thickness | Duplex 2205 stainless steel construction with 3.2 mm minimum wall thickness per NACE MR0175 |

- **Caution**: 

### Q: What materials are available for the collection tank in corrosive chemical environments?
**A**: Our collection tanks are available in Stainless Steel 316L for excellent corrosion resistance, Carbon Steel for cost-effective non-corrosive applications, and Fiberglass Reinforced Plastic (FRP) for highly corrosive chemical solvents.

### Q: What safety features are included in the solvent collection tank?
**A**: Each tank includes a pressure relief valve for overpressure protection, a manhole/access port for safe inspection and maintenance, and a level sensor to prevent overfilling and ensure proper inventory management.

### Q: How does the collection tank integrate with solvent recovery systems?
**A**: The tank features an inlet nozzle for receiving recovered solvents from distillation units, an outlet valve for controlled discharge to downstream processes or storage, and is designed for temporary holding to maintain continuous recovery operations.
