Olefinverbund Integration

Chemistry & Engineering

Reaction Equation	Calcination
Thermodynamics	Endothermic
Catalyst System	None
Reactor Class	Kiln
Process Considerations	Dead burned for refractories.

Extraterrestrial Production Pattern

1. MgCO₃ → MgO + CO₂ (calcination at 700-1000°C)
2. Mg(OH)₂ → MgO + H₂O (dehydration)
3. Seawater + Ca(OH)₂ → Mg(OH)₂ → MgO
4. Dead-burned MgO at 1500-2000°C for refractories

Applications

• Refractory linings
• Antacid (milk of magnesia)
• Animal feed supplement
• Cement and fertilizer

Reaction Diagram

Overall Reaction: Mg(OH)2 -> MgO + H2O (or MgCO3 -> MgO + CO2)

Unit Operations

Process steps following chemical engineering unit operation principles:

Step	Operation	Description
1	Raw Material Prep	Crush magnesite or prepare Mg(OH)₂
2	Calcination	Heat to 700-1000°C in kiln
3	Dead-Burning	Optionally heat to 1500-2000°C for refractory grade
4	Cooling	Cool in counterflow cooler
5	Grinding	Mill to desired particle size
6	Classification	Separate into grade specifications

**Key S88 Concepts:**
- **Process Cell**: The physical grouping containing all equipment for this process
- **Unit**: The major equipment that performs the synthesis
- **Equipment Modules**: Individual pieces of equipment (reactors, columns, etc.)
- **Unit Procedure**: The sequence of operations to produce the product
- **Phases**: The lowest level of procedural control (e.g., REACT, SEPARATE, PURIFY)

Key S88 Concepts:
• Process Cell: Physical grouping containing all equipment
• Unit: Major equipment performing synthesis
• Equipment Modules: Individual pieces (reactors, columns, etc.)
• Phases: Lowest level of procedural control (REACT, SEPARATE, etc.)
