# Industrial Specification: Gas Reforming Unit

## 1. Technical Definition
A unit that converts hydrocarbon feedstocks into synthesis gas (syngas) containing hydrogen and carbon monoxide for use in direct reduction iron processes.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **25-35 bar operating pressure, 800-950°C catalyst bed temperature, 2.5-4.0 m³/s syngas flow rate**. Failure boundary: **Catalyst bed temperature exceeding 1050°C causes nickel catalyst sintering, pressure differential across reformer tubes exceeding 15 bar causes tube rupture, steam-to-carbon ratio below 2.0 leads to carbon deposition**, Mechanism: **Metal dusting corrosion at 400-800°C due to carbon supersaturation (ac &gt; 1), thermal stress cracking from ΔT &gt; 150°C across tube walls, creep rupture at sustained temperatures above 900°C with stress &gt; 80 MPa**.

### 2.1 Analytical Physics Model
Governed by the **LMTD Logarithmic Mean Temperature Difference**:

> **Primary Equation**: $Q = U \cdot A \cdot \Delta T_{lm}$  
> **Engineering Impact**: Sizing validation for pasteurization and cooling tunnels.

| Symbol | Variable Definition | Localized Reference |
| :--- | :--- | :--- |
| U | Heat Transfer Coeff | Engineering Constant |
| A | Area | Engineering Constant |
| \Delta T_{lm} | LMTD | Engineering Constant |

### 2.2 FMEA (Failure Mode & Effects Analysis)
| Event Trigger | Severity | Failure Mode | Mitigation Strategy |
| :--- | :--- | :--- | :--- |
| Feedstock sulfur content &gt; 50 ppm poisoning nickel catalyst active sites | 8 | Catalyst deactivation reducing hydrogen yield by &gt;40% within 72 hours | Install dual-bed zinc oxide guard vessels with automatic bypass at H₂S &gt; 30 ppm |
| Burner flame impingement creating localized tube wall temperatures &gt; 1000°C | 8 | Reformer tube hot spots leading to circumferential cracks at 0.5 mm/year growth rate | Implement infrared pyrometer array with automatic burner tilt adjustment maintaining ΔT &lt; 50°C |
