1. What is a CO₂ recovery system, and how does it work?

The CO₂ recovery system is an add-on to your existing dry ice production operation. It captures and recovers vented CO₂ gas that is unused during the regular manufacturing process, ensuring it can be utilized to make more dry ice.

2. How does the CO₂ recovery system lower the conversion ratio for dry ice production?

The CO₂ recovery system can reduce the conversion ratio from 2.2 lbs of liquid CO₂ to 1 lb of dry ice to an improved ratio of 1.3 lbs of liquid CO₂ to 1 lb of dry ice. This results in significant savings in CO₂ usage or increased dry ice production with the same amount of liquid CO₂.

3. Can the CO₂ recovery system be integrated into my existing dry ice production setup?

Yes, the CO₂ recovery system is designed to seamlessly integrate with your current dry ice production equipment. It can be easily added to enhance the efficiency of your operations.

4. Does the recovered and reliquefied CO₂ from the CO₂ recovery system go back into the bulk CO₂ tank?

No, the recovered and reliquefied CO₂ from the CO₂ recovery system does not go back into the bulk CO₂ tank. Instead, the new liquid CO2 is directed through a valve into the piping that feeds liquid to the pelletizer. It is important to note that gas companies have strict regulations prohibiting the introduction of external substances or recovered CO₂ back into the bulk CO₂ tank. Our CO₂ recovery system ensures compliance with these regulations while maximizing production output and minimizing waste by delivering a continuous flow of high-quality liquid CO₂ to the pelletizer.

5. How much liquid CO₂ can I save by implementing the CO₂ recovery system?

By incorporating the CO₂ recovery system, you can save up to 40% of liquid CO₂ that would otherwise be exhausted during the dry ice manufacturing process.

6. Does the CO₂ recovery system require any additional equipment or modifications to my existing setup?

The CO₂ recovery system is designed to be easily installed alongside your current dry ice production equipment, requiring minimal additional equipment or modifications.

7. What are the benefits of using the CO₂ recovery system for my dry ice production?

The CO₂ recovery system offers two primary benefits: significant cost savings in CO₂ procurement by reducing waste and increased dry ice production capacity with the same amount of liquid CO₂.

8. Will implementing the CO₂ recovery system affect the quality of the dry ice produced?

No, the CO₂ recovery system has no impact on the quality of the dry ice. It ensures that the recovered CO₂ gas is of the same high quality as the liquid CO₂ used in the production process. The process is a closed-loop system, which eliminates the chance of any contamination.

9. Are there any specific operational considerations or maintenance requirements for the CO₂ recovery system?

The CO₂ recovery system is designed for easy operation and requires minimal maintenance. Regular checks and maintenance of the system are recommended to ensure optimal performance.

10. What kind of return on investment can I expect by implementing the CO₂ recovery system?

Implementing the CO₂ recovery system can result in significant cost savings on CO₂ procurement and increased production capacity. The return on investment will depend on your specific production volume and CO₂ usage, but in many cases the ROI period can be 12 months or less.
