Product Overview
The liquid CO₂ recovery system is designed for food processing plants to capture and purify CO₂-rich off-gas from decarbonization processes, producing high-purity liquid CO₂ (≥99.9% purity) that meets national industrial-grade standards. This system is ideal for environments with high CO₂ waste concentrations, helping to enhance economic value and meet environmental regulations.
Product Features
- High Recovery Efficiency: Achieves over 75% CO₂ recovery, significantly improving resource utilization.
- High Purity: Produces liquid CO₂ with ≥99.9% purity, suitable for applications in the beverage, food, and other industries.
- Stable Operation: Features a well-designed process flow for safe, stable, and cost-effective operation.
- Environmental and Economic Benefits: Reduces CO₂ emissions effectively, providing both environmental and economic value.
Applications
- Beverage and Food Processing: Used in carbonated drinks, beer, and food preservation.
- Tobacco Industry: Supports moisture retention and gas filling in tobacco production.
- Welding and Aluminum Processing: Used as a shielding gas in welding and surface treatment for aluminum products.
- Other Industries: Applied in CO₂ recovery for nitrogen fertilizer production, hydrogen refining, and other industrial processes.
