Pressure Vessel Standards: Liquid carbon dioxide storage tanks are generally considered pressure vessels, and their design, manufacturing, and use should comply with the relevant pressure vessel standards. In China, common pressure vessel standards include GB150 "Steel Pressure Vessels" and GB18435 "Storage Tanks." Safety Standards: The use of liquid carbon dioxide storage tanks should adhere to relevant safety standards and regulations. For instance, in China, the safe operation of liquid carbon dioxide storage tanks should follow standards such as GB50028 "Design Code for Petroleum and Chemical Enterprises" and GB50016 "Building Design Fire Prevention Code." Inspection and Testing Standards: The inspection and testing of liquid carbon dioxide storage tanks should comply with the corresponding standards and regulations. For example, regular inspections of liquid carbon dioxide storage tanks can refer to standards like GB/T 19638 "Code for Periodic Inspection of Pressure Vessels." Environmental Protection Standards: The use of liquid carbon dioxide storage tanks should comply with relevant environmental protection standards and regulations. For instance, in China, the exhaust emissions from liquid carbon dioxide storage tanks should meet standards such as "Emission Standards of Air Pollutants."

Technical specifications for carbon dioxide storage tanks can be established 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 published some standards related to pressure vessels, such as ISO 9809-1 and ISO 9809-2, covering design, manufacturing, and inspection requirements for steel cylinders. GB Standards: The China National Standardization Administration has issued a series of standards related to pressure vessels, such as GB 150 "Pressure Vessels" and GB 5099 "Steel Cylinders," including 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 published 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 relevant standards in the food and beverage industry and industry-specific standards. When using carbon dioxide storage tanks, appropriate technical specifications should be selected based on specific application requirements and local regulations, ensuring that the design, manufacturing, and use of the tanks comply with the relevant standards and specifications.

Common disadvantages of corrosion in pressure vessels during use include: - Chemical media: Certain chemical substances, such as acids, bases, and salts, are corrosive. When these substances come into contact with the vessel material, corrosion may occur. - Humidity and moisture: High humidity environments or long-term exposure to moisture can lead to corrosion on the vessel surface, especially when oxygen is present, which may accelerate the corrosion rate. - Rusting: When the protective layer on the vessel surface (such as coatings or plating) is damaged or destroyed, rusting may occur. Rusting can damage the surface and may lead to further corrosion. - Electrochemical corrosion: When different metals or metals and non-metals come into contact, electrochemical corrosion cells may form, which can cause localized corrosion on the vessel surface. - Welding defects: Defects like weld porosity and cracks may be introduced during the welding process. These defects can become starting points for corrosion. Corrosion weakens the structural integrity of the vessel, increasing the risk of leakage or rupture. Therefore, regular inspection and maintenance of the corrosion-resistant coating, coating, or plating on pressure vessels are important. If corrosion issues are found, timely measures should be taken to repair or replace the damaged parts. Additionally, selecting appropriate materials and corrosion prevention measures, as well as proper operation and maintenance methods, can reduce the risk of corrosion in pressure vessels. Adhering to relevant safety operating procedures and standards ensures the safe operation of pressure vessels.

When applying paint to carbon dioxide storage tanks, the following issues should be taken into account: Surface Preparation: Prior to painting, thorough surface preparation of the tank is essential. This includes cleaning the surface, removing grease, dirt, and old coatings to ensure the paint adheres properly and maintains quality. Paint Selection: Choosing the right paint for carbon dioxide storage tanks is crucial. The paint should be corrosion-resistant, heat-resistant, and chemical-resistant to protect the tank surface from corrosion and damage. Painting Techniques: The selection and operation of painting techniques are vital for the quality and uniformity of the coating. Appropriate painting equipment and methods should be chosen to ensure the paint covers the entire tank surface evenly, avoiding drips and runs. Coating Thickness: The thickness of the coating is critical for the tank's protection. The thickness should be controlled according to the paint requirements and the tank's operating environment to ensure the coating's protective performance and lifespan. Drying and Curing: After the coating is applied, sufficient time must be allowed for drying and curing. Follow the correct drying time and conditions as per the paint requirements to ensure the coating's quality and performance. Safety Measures: Appropriate safety measures must be taken during the painting process, including wearing protective eyewear, respirators, and protective clothing to ensure the safety of the operators. Quality Inspection: After painting is completed, a quality inspection should be conducted, including the appearance, adhesion, and thickness of the coating. Any issues or defects should be repaired and addressed promptly. It is important to note that painting carbon dioxide storage tanks should be carried out by professionals.
