Process Overview
1. CO₂ Recovery & Fermentation Gas Handling
- Foam Trap: Removes foam from raw CO₂ feed gas.
- Low Pressure Scrubber: Washes out water-soluble impurities (e.g., alcohols, aldehydes, ketones).
- Blower with VFD: Boosts gas pressure for efficient compressor suction.
2. Compression & Gas Purification
- CO₂ Receiver & Compressors: Increases gas pressure up to 20 kg/cm².
- High Pressure Scrubber: Efficiently removes water-soluble impurities using structured packing.
- Deodorizer Towers: Filled with activated carbon to remove odorous and microbial impurities; towers are steam-regenerated.
- Precooler & Dual Drier Towers: Reduces temperature and removes remaining moisture to required limits.
3. Liquefaction & Purification
- Refrigeration System: Uses NH₃ refrigerant to liquefy CO₂ at -23°C and 20 kg/cm².
- LCO₂ Storage: Final liquid CO₂ is stored in tanks for transport and use
4. Dry Ice Production (Optional Module)
- Converts food-grade Liquid CO₂ into solid dry ice via hydraulic press.
- Operates via PLC automation or manual control.
- Conversion Ratio: ~2.3–2.5 kg Liquid CO₂ per kg of Dry Ice.
- Vaporized CO₂ is either vented or recovered through a closed-loop compression system.
