# Industrial Specification: Industrial Chemical Crystallization Unit

## 1. Technical Definition
Standalone machine for controlled solid crystal formation from chemical solutions

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.1-2.0 MPa (1-20 bar) pressure, 20-80°C temperature, 0.5-5.0 m³/h flow rate**. Failure boundary: **Crystallizer wall stress exceeds 150 MPa yield strength of 316L stainless steel at 2.5 MPa internal pressure with 120°C thermal gradient**, Mechanism: **Thermal-mechanical fatigue from cyclic heating/cooling during batch processing causes crack initiation at stress concentrators (nozzle welds, agitator penetrations)**.

### 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 |
