CO₂ RECOVERY PLANTS

"Energy-Efficient. High-Purity. Built for Performance"

With over 42 years of experience in carbon dioxide recovery, Prime Gases Pvt. Ltd. is a trusted leader in designing and delivering customized CO₂ recovery plants tailored to your operational needs. Using our proprietary in-house technology, we offer state-of-the-art recovery systems suitable for multiple CO₂ sources, including:

  • Fertilizer plants (Ammonia-based)
  • Distilleries & Ethanol plants (Fermentation)
  • Breweries

Our plants are designed to recover CO₂ at capacities ranging from 100 kg/hr to 7000 kg/hr, while maintaining 99.99% purity, meeting Food Grade and ISBT standards.

  • Meets ISBT and Food Grade specifications
  • High energy efficiency and cost-effective design
  • Fully expandable for future plant upgrades
  • Comprehensive after-sales service and support
  • Suitable for a wide range of industries
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.
