- Rectification: Fractional distillation separates CO₂ from other gases.
- Liquefaction: Condensing evaporator converts purified CO₂ into liquid phase.
- Storage: Liquid CO₂ is stored in insulated tanks at -20°C.
Applications
- Oil & Gas: Enhanced oil recovery (EOR) and natural gas sweetening.
- Manufacturing: Welding shielding gas, metal casting cooling.
- Fire Safety: CO₂ fire suppression systems.
- Food & Beverage: Carbonation, freezing, and packaging.
- Healthcare: Medical-grade CO₂ for laparoscopy and cryotherapy.
Service Support
- Turnkey Solutions: Installation, commissioning, and operator training.
- Spare Parts: Inventory of critical components for quick replacements.
