Common defects in CO2 storage tanks may include deformation during use. Here are some causes that can lead to tank deformation: Overpressure: When the internal pressure of the tank exceeds its design pressure, deformation may occur. This could be due to operational errors, system failures, or other reasons. Temperature Changes: CO2 storage tanks expand and contract with temperature changes, and if the temperature fluctuates too much or too quickly, it may cause deformation. Internal Corrosion: If there is internal corrosion in the tank, it can damage the structural integrity of the tank, leading to deformation. External Damage: External impacts, compressions, or other physical damages can cause tank deformation. Incorrect Installation or Use: Incorrect installation or usage methods can lead to uneven stress on the tank, causing deformation. Tank deformation can reduce the structural integrity of the tank and even pose risks of leakage or rupture. Therefore, it is important to regularly inspect and maintain the integrity of the tank, as well as to follow proper operational and installation procedures. If tank deformation or other defects are detected, the tank should be immediately discontinued from use and professional assistance should be sought for inspection and repair. Do not attempt to repair or continue using a defective tank to ensure operational safety.

Detailed parameters for CO2 storage tanks may vary based on specific design and operational requirements. Here are some common parameters for CO2 storage tanks: - Capacity: The capacity of CO2 storage tanks can vary as per demand, with common ranges spanning from a few thousand to several tens of thousands of liters. - Pressure: The design working pressure for CO2 storage tanks typically falls between 15-25 MPa (Megapascals), with the exact pressure depending on the application scenario and requirements. - Material: CO2 storage tanks are commonly made of high-strength materials such as carbon steel or stainless steel. The choice of material depends on the storage environment and requirements. - Dimensions: The physical dimensions of CO2 storage tanks also vary based on capacity and design. Common shapes include cylindrical, spherical, or cubical. - Level Control: CO2 storage tanks are often equipped with level control systems for monitoring and regulating the level of liquid CO2. These systems usually include level sensors and control valves. - Pressure Control: Internal pressure control systems are commonly fitted in CO2 storage tanks for monitoring and controlling the internal gas pressure. These systems usually include pressure sensors and safety valves. It is important to note that specific parameters for CO2 storage tanks can differ among manufacturers, application scenarios, and standards. When selecting and using CO2 storage tanks, it is essential to adhere to relevant safety operating procedures and guidelines, and consult with experts to obtain accurate parameter information.

In accordance with China's "Regulations for the Safe Supervision of Pressure Vessel Technologies," carbon dioxide storage tanks are classified as Category II pressure vessels. According to these regulations, pressure vessels are categorized as follows: - Category I: Pressure vessels with working pressures of 10 MPa (MegaPascals) or more, such as steam boilers and pressure vessels. - Category II: Pressure vessels with working pressures between 0.1 MPa and 10 MPa, such as air compressors and liquefied gas storage tanks. - Category III: Pressure vessels with working pressures between 0.05 MPa and 0.1 MPa, such as storage tanks. - Category IV: Pressure vessels with working pressures less than 0.05 MPa, such as gas cylinders. Based on this classification, carbon dioxide storage tanks typically operate at pressures above 0.1 MPa, thus falling into Category II. It is important to note that specific classification criteria may vary due to different regional regulations and standards. When using and managing carbon dioxide storage tanks, it is essential to comply with the relevant laws and standards.

If a leak in the CO2 storage tank is detected, the following procedures should be taken immediately: Confirm the leak location: First, identify the exact location of the leak, which can be done through auditory detection, observation, or using gas detection equipment. Emergency response: In the event of a leak, implement emergency measures immediately to ensure personnel safety. Evacuate staff to a safe area and notify relevant personnel and emergency services. Cut off the gas supply: Quickly shut off the CO2 supply source by closing valves or disconnecting power to stop the supply. Locate the leak: In a safe environment, use gas detection equipment or visual inspection to find the leak. Apply soap solution or other leak detection agents to potential leak points and observe for bubble formation. Seal the leaks: Once the leak location is confirmed, temporary sealing measures can be taken, such as using tape, sealant, or other reliable sealing materials for temporary repair. Ensure that the sealing is secure and effective in preventing gas leakage. Repair and restoration: In a safe condition, conduct further repairs and restoration. Depending on the nature of the leak, it may be necessary to replace gaskets, repair or replace valves, etc. Repair and restoration work should be carried out by qualified personnel. Inspection and testing: After repairs and restoration, perform leak detection and testing to ensure that the leaks have been fully repaired and the tank's safety performance has returned to normal. It is important to handle CO2 storage tank leak issues with caution and follow relevant safety regulations and procedures.
