Technical specifications for carbon dioxide storage tanks can be formulated based on different application fields and/or regional standards. The following are some common technical specifications and standards for reference: ASME Standards: The American Society of Mechanical Engineers (ASME) has issued a series of standards for pressure vessels, including specifications for carbon dioxide storage tanks, such as ASME BPVC Section VIII Division 1 and ASME BPVC Section VIII Division 2. ISO Standards: The International Organization for Standardization (ISO) has released some standards related to pressure vessels, such as ISO 9809-1 and ISO 9809-2, covering design, manufacturing, and inspection requirements for steel gas cylinders. GB Standards: The China National Bureau of Standards has issued a series of standards related to pressure vessels, such as GB 150 "Pressure Vessels" and GB 5099 "Steel Gas Cylinders," which include design, manufacturing, and inspection requirements for carbon dioxide storage tanks. DOT Standards: The United States Department of Transportation (DOT) has issued some standards related to pressure vessels and cylinders, such as DOT-3AA and DOT-4BA, covering design, manufacturing, and transportation requirements for liquefied gas storage tanks. EN Standards: The European Committee for Standardization (CEN) has issued some standards related to pressure vessels, such as EN 13445 and EN 14382, covering design, manufacturing, and inspection requirements for liquefied gas storage tanks. Additionally, other industry standards and specifications may apply to carbon dioxide storage tanks based on specific application needs, such as those related to the food and beverage industry or specific industry standards. When using carbon dioxide storage tanks, it is essential to select appropriate technical specifications according to specific application requirements and local regulations, ensuring that the tank's design, manufacturing, and use comply with the corresponding standards and specifications.

Carbon dioxide storage tanks possess the following characteristics: - High-pressure Vessel: These tanks are typically designed as high-pressure vessels, capable of withstanding significant pressure. This is due to the fact that carbon dioxide requires high pressure to maintain a liquid state at room temperature. - High Oxidizing Property: Carbon dioxide has a high oxidizing property, which supports combustion. Therefore, when handling and storing carbon dioxide, precautions must be taken to prevent contact to avoid the risk of fire and explosion. - Low-temperature Storage: Carbon dioxide is in a gaseous state at room temperature but can be compressed into a liquid at lower temperatures. As a result, these tanks usually need to have good insulation properties to maintain the低温 of the stored liquid carbon dioxide. - High Density: Liquid carbon dioxide has a high density, allowing for the storage of large amounts of carbon dioxide in a relatively small volume. This makes carbon dioxide storage tanks useful in scenarios requiring substantial carbon dioxide supplies. - Safety Valves and Pressure Control: To ensure the internal pressure of the tank remains within a safe range, carbon dioxide storage tanks are usually equipped with safety valves and pressure control devices. These devices monitor and control the internal pressure of the tank to prevent excessive pressure from causing the tank to rupture. - Corrosiveness: Carbon dioxide has some corrosive properties, particularly in high humidity environments. Therefore, the materials and corrosion prevention measures for the tank need to consider the corrosiveness of carbon dioxide to ensure the tank's durability and safety. These characteristics make carbon dioxide storage tanks widely applicable in many industries, such as the food and beverage industry, fire suppression, and the gas industry. When using carbon dioxide storage tanks, it is necessary to follow relevant safety operating procedures and standards to ensure operational safety.

When using carbon dioxide cylinders, the following precautions should be taken: Safety Operation: Prior to operating a carbon dioxide cylinder, it is essential to be familiar with and adhere to the relevant safety operating procedures and guidelines. Ensure that operators have received necessary training and understand the cylinder's working principles, operating procedures, and emergency measures. Cylinder Inspection: Regularly inspect the external and internal condition of the carbon dioxide cylinder, including checking for corrosion, leaks, and welds on the cylinder walls. If any anomalies or damages are found, take immediate corrective or replacement actions. Cylinder Pressure Control: Ensure that the internal pressure of the cylinder remains within a safe range. Monitor and control the cylinder's pressure to avoid damage or safety risks from either excessive or insufficient pressure. Fire Prevention Measures: Carbon dioxide is a flammable gas, and fire prevention measures must be taken during use. Avoid open flame work near the cylinder and ensure the surrounding environment is flame-free. Leakage Management: In the event of a carbon dioxide leak, appropriate emergency measures should be taken immediately. Notify relevant personnel promptly, ensure a safe evacuation, and implement measures to prevent the spread of the leak. Cylinder Maintenance: Regularly maintain and service the cylinder, including cleaning, lubrication, and corrosion prevention. Follow the manufacturer's recommendations and guidelines to ensure the cylinder operates normally and has a long service life. Compliance: Adhere to local regulations, standards, and specifications to ensure the cylinder's design, manufacture, installation, and use meet the required standards. It is crucial to strictly follow safety operating procedures when using carbon dioxide cylinders and to collaborate with relevant personnel to ensure the cylinder's safety and reliability.

When using carbon dioxide tanks, the following safety procedures must be adhered to ensure safety: Tank Operator Training: All operators must undergo training to understand the characteristics, operational requirements, and safety measures of carbon dioxide tanks. The training should include safe tank operation, leak handling, emergency procedures, etc. Safety Operating Procedures: Establish and follow relevant safety operating procedures, including tank start-up, shutdown, inspection, and maintenance. Operators should operate according to the procedures to ensure safe tank operation. Leak Handling: Develop a leak handling program including leak alarms, emergency shutdown, and isolation of the leak source. Operators should be familiar with the leak handling procedures and be able to respond quickly and correctly to leak incidents. Fire Prevention Measures: Carbon dioxide is flammable, so fire prevention measures must be observed when in use. Smoking, open flames, or placing flammable materials near the tank is prohibited. Ensure that fire protection facilities around the tank are intact and conduct fire drills regularly. Waste Gas Emission: Properly discharge waste gases produced when using carbon dioxide tanks to avoid CO2 accumulation in enclosed spaces, which can lead to asphyxiation and safety risks. Ensure that the waste gas emission system is unobstructed and functioning properly. Regular Inspection and Maintenance: Regularly inspect the tank's appearance, seal integrity, valves, and pipe connections. Repair or replace promptly any abnormalities or damages. Also, regularly check and maintain safety valves, pressure sensors, and other accessories. Emergency Response Plan: Develop and implement an emergency response plan including procedures for leak incidents, evacuation, and first aid measures. Operators should be familiar with the emergency response plan and conduct drills regularly. Monitoring and Alarm Systems: Install and maintain monitoring and alarm systems for the tank.
