Dry Ice Tail Gas Recovery System

Product Overview

The Dry Ice Tail Gas Recovery System is a high-efficiency, energy-saving gas recovery solution specifically designed for the CO₂ tail gas generated during dry ice production. During dry ice manufacturing, liquid CO₂ is compressed into solid dry ice, producing significant amounts of gaseous CO₂ as a by-product. This system recovers and converts tail gas into food-grade liquid CO₂, with approximately 1.2 tons of liquid CO₂ recoverable per ton of dry ice produced, effectively reducing production costs and maximizing resource utilization.

Working Principle

The system utilizes gas condensation, liquefaction, and separation technologies to cool and condense CO₂ tail gas generated during dry ice production. Subsequent separation and purification processes remove impurities, producing high-purity liquid CO₂. Equipped with automatic control and monitoring devices, the system enables fully automated operation and allows process parameters to be adjusted flexibly based on production scale.

Key Features

• Advanced and Mature Technology: Streamlined process flow ensures stable, reliable operation under various production conditions.
• High Economic Efficiency: Low power consumption and high liquid CO₂ recovery rate significantly reduce operating costs.
• High Automation: Supports remote network monitoring and unattended operation, improving operational efficiency and safety.
• Customizable Design: Process and equipment can be optimized to meet specific production requirements.
• Resource Conservation: Recovers approximately 1.2 tons of liquid CO₂ per ton of dry ice, achieving efficient use of energy and raw materials.

Applications

• Dry Ice Production: Recovers tail gas to improve energy efficiency and enable CO₂ reuse.
• Brewing & Fermentation: Captures CO₂ tail gas generated during fermentation and converts it into high-purity liquid CO₂.
• Food Processing: Supplies food-grade liquid CO₂ for preservation, packaging, and various food processing operations.
