Cryogenic Liquid Carbon Dioxide (CO2) Storage Tanks

Cryogenic Liquid Carbon Dioxide (CO2) Storage Tanks: Efficient and Reliable Solutions

Liquid carbon dioxide (CO2) storage tanks are crucial for a variety of industrial applications, providing a safe and efficient method for storing and dispensing this versatile gas. These tanks are designed to maintain the CO2 in its liquid state at cryogenic temperatures, typically around -40°C.  Our Carbon Dioxide Storage Tank are engineered for optimal performance and longevity, adhering to the highest industry standards.

Tank Types and Insulation Technologies:

We offer two primary types of liquid CO2 storage tanks, each with distinct insulation properties to minimize heat ingress and maintain consistent temperature:

• Vacuum Powder Insulated Tanks:  These tanks utilize a double-walled construction with a vacuum between the inner and outer vessels. This vacuum space is filled with a special powder insulation, such as perlite, to further reduce heat transfer, providing exceptional thermal performance and minimizing CO2 vaporization.  This insulation method is ideal for applications demanding extended storage times and minimal product loss.

• Polyurethane Foam Insulated Tanks: These tanks employ a thick layer of high-density polyurethane foam applied directly to the outer surface of the inner vessel. This foam provides excellent insulation, offering a cost-effective solution for applications where moderate storage durations are sufficient. The polyurethane foam insulation ensures a balance between thermal efficiency and economic viability.

• High Vacuum Multi-Layer Insulated Tanks: This is a advanced technology using a double-walled construction with a high vacuum degree and multi-layer insulation materials. This type of tank offers superior insulation performance, minimizing heat transfer and maintaining CO2 temperature for extended periods.

The construction materials, typically OCr18Ni9 or 16MnDR steel (depending on the specific operating conditions and pressure requirements), are selected for their cryogenic compatibility, strength, and resistance to corrosion.  These materials ensure the structural integrity and safety of the tank over its operational lifespan.

Applications Across Industries:

Our liquid CO2 storage tanks serve a diverse range of industries, including:

• Metallurgy:  Used in various metal processing applications, such as welding, cutting, and inerting.

• Steel Structure Fabrication:  Employed in welding processes to create strong and durable steel structures.

• Automobile Manufacturing:  Utilized in welding, paint spraying, and other manufacturing processes.

• Modern Agriculture:  Used for controlled atmosphere storage of fruits and vegetables, extending shelf life and preserving quality.

• Food and Beverage Industry: In carbonation, packaging, and preservation processes to maintain the freshness and quality of food and beverage products.

• Pharmaceuticals and Biotechnology:  Used in research, development, and manufacturing processes.

• Water Treatment: Employed for pH control and re-carbonation processes.

Key Advantages:
