# Industrial Specification: Integrated Process Control System (PCS)

## 1. Technical Definition
A centralized automation system that monitors and controls the continuous ammonium nitrate melt production and concentration process.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.8-1.2 MPa (8-12 bar) at 180-210°C**. Failure boundary: **Pressure exceeding 1.5 MPa (15 bar) at 210°C or dropping below 0.6 MPa (6 bar) at 180°C**, Mechanism: **Thermal decomposition of ammonium nitrate melt initiating at 210°C under pressure exceeding 1.5 MPa, following Arrhenius kinetics with activation energy of 125 kJ/mol**.

### 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 |
| :--- | :--- | :--- | :--- |
| Corrosion-induced pitting in 316L stainless steel control valve stems from chloride stress corrosion cracking at &gt;50 ppm Cl⁻ concentration | 8 | Valve stem seizure causing loss of flow control within 2.3 seconds | Duplex stainless steel (UNS S32205) valve construction with cathodic protection at -850 mV vs. Ag/AgCl reference |
| Electromagnetic interference from 60 Hz harmonics exceeding 150 V/m field strength in control cabinet | 8 | PLC processor memory corruption manifesting as PID loop oscillation at 0.5 Hz frequency | Faraday cage enclosure with 80 dB attenuation at 60-1000 Hz and optical isolation of I/O signals |
