Prior to using the CO2 storage tank, the following preparations must be made: - Inspect the tank: Check for any visible damage, corrosion, or oil leakage on the tank's exterior. Ensure the structural integrity and safety of the tank. - Check valves and pipes: Verify that the tank's inlet and outlet valves and pipe connections are functioning properly, with no leaks or loose fittings. Ensure valves operate smoothly and reliably. - Inspect safety accessories: Check that safety accessories such as safety valves, pressure sensors, and temperature sensors are functioning correctly. Confirm that their set parameters meet requirements. - Inspect the level measurement system: Verify the accuracy and reliability of the level measurement system. Calibrate the level sensors to ensure accurate level readings. - Check the pressure relief device: Ensure that the tank's pressure relief device (e.g., safety valve) is working properly. Confirm that the set pressure of the relief device meets requirements. - Check gas quality: Ensure the CO2 gas in the tank meets quality standards, with no impurities or contaminants. - Inspect fire protection equipment: Ensure that fire protection equipment around the tank is in good condition and check that fire extinguishers, sprinkler systems, etc., are functioning properly. - Train operators: Operators should receive training on the characteristics, operation requirements, and safety measures of the CO2 storage tank. Training should include safe operation, leak handling, and emergency procedures. These preparations ensure the CO2 storage tank is in good condition before use and guarantees the safety and reliability of operation. When conducting these preparations, follow relevant safety operation procedures and have personnel perform the operations.

When planning carbon dioxide storage tanks, consider the following requirements: Safety Distance: Tanks should maintain an adequate safety distance from surrounding buildings, equipment, and personnel to prevent injuries and losses in case of accidental incidents. Specific requirements for safety distances can be determined based on 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 cycles, and supply demands. Tank Layout: The layout should facilitate operation and maintenance while meeting safety and environmental protection requirements. Sufficient spacing between tanks should be ensured for ease of operation and maintenance. Tank Material: Select appropriate materials for manufacturing the tank to ensure its corrosion and pressure resistance. Common materials include carbon steel, stainless steel, etc. Safety Equipment: Tanks should be equipped with necessary safety equipment, such as safety valves, pressure and temperature sensors, to ensure safe operation. Leak Prevention: Measures should be taken to prevent CO2 leaks, such as sealed valves and leak detection systems. Appropriate leak handling measures and emergency response plans should also be in place. Environmental Impact Assessment: Environmental impact assessments should be conducted when planning tanks to evaluate their impact on the surrounding environment and implement measures for environmental protection. Regulations and Standards: Compliance with local regulations and standards is required when planning tanks, including building codes, safety specifications, and environmental protection requirements. It is important to note that planning carbon dioxide storage tanks should be carried out by engineers or relevant institutions to ensure compliance with safety and environmental protection requirements. Consulting local authorities for advice and guidance is also necessary.

Carbon dioxide recovery is a technology aimed at capturing carbon dioxide from industrial emissions sources or the atmosphere and storing or utilizing it to reduce carbon dioxide emissions. Here are some common carbon dioxide recovery technologies: Coal-fired power plant carbon dioxide recovery: In coal-fired power plants, the carbon dioxide produced by burning coal can be captured and recovered. Common methods include carbon capture technologies, which separate carbon dioxide from flue gas and store or utilize it. Industrial emissions source carbon dioxide recovery: Many industrial processes produce carbon dioxide that can be treated with capture and recovery technologies. For example, carbon dioxide produced during the production processes of industries such as steel, cement, and chemicals can be recovered to reduce emissions. Atmospheric carbon dioxide capture: Carbon dioxide in the atmosphere can also be recovered using direct air capture technologies. This technology uses adsorbents or chemical reactions to capture and separate carbon dioxide from the atmosphere, then store or utilize it. Carbon dioxide utilization: Captured carbon dioxide can be used to produce valuable chemicals and fuels. For instance, through carbon dioxide catalytic conversion technology, carbon dioxide can be converted into fuels like ethanol or chemicals. The development of carbon dioxide recovery technologies aims to reduce greenhouse gas emissions and mitigate climate change. However, these technologies are still under development and research, requiring further technological breakthroughs and practical verification for large-scale application.

In the event of a CO2 cylinder leak, immediate action should be taken as follows: Ensure personnel safety: First, ensure that people evacuate the leak area quickly and move away from any potential hazards. If necessary, use appropriate personal protective equipment, such as respirators and protective suits. Cut off the gas source: As soon as possible, shut off the CO2 supply source to stop further leakage. Close related valves or switches, or disconnect from the cylinder. Prevent ignition sources: Ensure there are no open flames or other potential heat sources that could cause a fire in the leak area. If there is a fire risk, take appropriate fire-fighting measures immediately. Ventilation: Activate ventilation equipment to increase air circulation, which helps dilute and expel the leaked CO2 gas. Ensure that the ventilation equipment is functioning properly and that the ventilation system does not introduce CO2 gas to other areas. Seal the leak point: If possible, attempt to seal the leak point using suitable materials or methods to reduce or stop the leakage. This may require assistance from personnel. Notify relevant departments: Promptly inform emergency, environmental protection, or other relevant agencies of the leak situation and act according to their instructions. Please note that handling a CO2 cylinder leak is a dangerous task and should only be performed by trained and experienced personnel. Always follow relevant safety operation procedures and guidelines during the process.
