CO2 Recovery & Liquefaction Unit

 

COâ‚‚ Recovery & Liquefaction Unit

 

Product Overview
CRYO-TECH’s CO₂ Recovery & Liquefaction Unit is a turnkey solution designed to efficiently capture, purify, and liquefy CO₂ from industrial waste streams. By integrating compression, drying, rectification, and refrigeration processes, this unit produces high-purity liquid CO₂ (industrial and food-grade) for applications in oilfield mining, welding, metal casting, firefighting, food processing, and healthcare.

Key Features

 

  1. Energy-Efficient Refrigeration: Uses eco-friendly refrigerants to minimize energy consumption (0.3–0.34 kW·h/Nm³ CO₂).
  2. Modular Design: Skid-mounted configuration for rapid on-site installation and scalability.
  3. Robust Compression: Mature screw compressor technology with low maintenance requirements and high reliability.
  4. Precision Purification: Advanced desulfurization and drying systems ensure water content ≤20ppm and H₂S ≤0.1ppm.
  5. Flexible Operation: Adjustable load capacity to handle varying COâ‚‚ concentrations in feed gas.

Process Flow

 

  1. Compression: COâ‚‚-rich gas is pressurized using a screw compressor.
  2. Purification: Desulfurization and drying remove impurities (Hâ‚‚S, moisture).
  3. Rectification: Fractional distillation separates COâ‚‚ from other gases.
  4. Liquefaction: Condensing evaporator converts purified COâ‚‚ into liquid phase.
  5. 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: COâ‚‚ fire suppression systems.
  • Food & Beverage: Carbonation, freezing, and packaging.
  • Healthcare: Medical-grade COâ‚‚ for laparoscopy and cryotherapy.

Service Support

 

  • Turnkey Solutions: Installation, commissioning, and operator training.
  • Spare Parts: Inventory of critical components for quick replacements.
  • Performance Optimization: Regular maintenance and energy audits.
