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 published 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 Committee for Standardization has issued a series of standards related to pressure vessels, such as GB 150 "Pressure Vessels" and GB 5099 "Steel Gas 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-specific 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 industry-specific standards. When using carbon dioxide storage tanks, appropriate technical specifications should be selected based on specific application requirements and local regulatory requirements, ensuring that the design, manufacturing, and use of the tanks comply with the corresponding standards and specifications.

When planning carbon dioxide storage tanks, the following requirements should be considered: - Safety Distance: Tanks should maintain adequate safety distances from surrounding buildings, equipment, and personnel to prevent injuries and losses in the event of accidents. Specific safety distance requirements can be determined according to local regulations and standards. - Tank Capacity: Determine the tank's capacity based on actual needs and usage. The capacity selection should consider factors such as the amount of CO2 used, storage duration, and supply requirements. - Tank Layout: The layout should facilitate operation and maintenance, as well as comply with safety and environmental protection requirements. There should be sufficient spacing between tanks for ease of operation and maintenance. - Tank Material: Choose appropriate materials for manufacturing the tank to ensure corrosion and pressure resistance. Common materials include carbon steel and stainless steel. - Safety Equipment: Tanks should be equipped with necessary safety equipment, such as safety valves, pressure sensors, and temperature sensors, to ensure safe operation. - Leak Protection: Measures should be taken to prevent CO2 leakage, such as sealed valves and leak detection systems. Corresponding leak handling measures and emergency response plans should also be in place. - Environmental Impact Assessment: An environmental impact assessment should be conducted when planning tanks to evaluate their impact on the surrounding environment and implement appropriate measures for environmental protection. - Regulations and Standards: Compliance with local regulations and standards, including building codes, safety regulations, and environmental protection requirements, is essential when planning tanks. It is important to note that planning carbon dioxide storage tanks should be conducted by engineers or relevant agencies to ensure compliance with safety and environmental protection requirements. Consulting with local authorities for advice and guidance is also necessary.

In recent years, the surge in the development of low-temperature liquid storage tanks can be attributed to the following factors: 1. Increased Energy Demand: With economic growth and population expansion, the demand for energy has been on the rise. Low-temperature liquid storage tanks are primarily used for storing liquefied natural gas (LNG), liquid oxygen (LOX), liquid nitrogen (LIN), and other low-temperature liquid energy sources to meet the growing energy needs. 2. Greenhouse Gas Emission Reduction: These tanks can store and transport liquid carbon dioxide (CO2) for carbon capture and storage (CCS) technology, helping to reduce greenhouse gas emissions. As environmental protection and climate change concerns intensify, the demand for low-temperature liquid storage tanks in the CCS field has also increased accordingly. 3. Industrial Development Needs: The application of low-temperature liquid storage tanks in the industrial sector is also expanding. For instance, in industries such as chemicals, pharmaceuticals, food and beverages, there is a need for storing and transporting low-temperature liquid raw materials or products like liquid nitrogen, liquid oxygen, and liquid ethylene. As these industries develop, so does the demand for low-temperature liquid storage tanks. 4. Technological Advancement and Innovation: In recent years, there have been continuous advancements and innovations in the design, manufacturing, and transportation of low-temperature liquid storage tanks. The application of new materials, optimization of tank structures, and improvements in safety control systems have made these tanks safer and more reliable, further propelling their peak development. In summary, factors such as increased energy demand, greenhouse gas emission reduction, industrial development needs, and technological advancement and innovation have collectively driven the peak development of low-temperature liquid storage tanks in recent years. As related industries continue to grow and technology advances, the demand for these tanks is expected to increase further.

Before using a CO2 cylinder, certain inspection and filling points must be addressed. Here are some common precautions: - Inspect cylinder exterior: Check for any visible damage, corrosion, or leakage signs on the cylinder. Ensure the shell is undamaged. - Inspect valves and fittings: Verify that the valves and fittings on the cylinder are securely fastened with no leakage. Ensure their proper operation. - Check the pressure gauge: Confirm that the cylinder's pressure gauge is functioning correctly and accurately. Replace or repair if abnormal. - Inspect the level indicator: Ensure the cylinder's level indicator is working properly and accurately displays the level. Repair or replace if abnormal. - Inspect the pressure relief device: Check if the cylinder's pressure relief device (such as a safety valve) is functioning correctly and set to the required pressure. Repair or replace if abnormal. - Inspect filling equipment: Ensure the filling equipment (such as filling pipes, pumps, etc.) is working properly with no leakage or blockage. Confirm safety and reliability. - Filling operation: During the filling process, note the following points: - Control the filling speed to avoid being too fast or slow. - Control the filling pressure to prevent exceeding the cylinder's rated pressure. - Monitor the level to ensure proper filling. - Regularly inspect filling equipment and valves to ensure normal operation. - Safety measures: Adhere to relevant safety regulations and procedures during the filling process. Operators should wear appropriate protective gear, such as static-resistant clothing and gloves. - Note that specific inspection and filling points may vary depending on the cylinder type and application. Before using a CO2 cylinder, check and operate according to relevant specifications and standards, and consult with experts to ensure safety and effectiveness.
