# Industrial Specification: Catalyst Baskets

## 1. Technical Definition
Specialized containers that hold catalyst pellets within high-pressure ammonia synthesis reactors

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **150-300 bar, 400-500°C**. Failure boundary: **Material yield strength exceeded at 350 bar internal pressure or 550°C thermal stress**, Mechanism: **High-cycle fatigue from pressure cycling (150-300 bar) combined with thermal expansion mismatch (ΔT=100°C) between Inconel 718 basket and catalyst pellets**.

### 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.
