Low-temperature CO2 storage tanks are equipment used for storing and transporting liquid CO2 at low temperatures. Here are some key points related to low-temperature CO2 storage tanks: Tank Structure: These tanks typically feature a double-walled design, with the inner wall for storing liquid CO2 and the outer wall for insulation. The interior is usually made of stainless steel or aluminum alloy, offering excellent corrosion resistance. Storage Temperature: The storage temperature for low-temperature CO2 storage tanks usually ranges from -40°C to -196°C, depending on specific application requirements. Temperature control is crucial to ensure the stability and safety of the liquid CO2. Storage Capacity: The capacity of low-temperature CO2 storage tanks can be selected based on actual needs, ranging from a few thousand to tens of thousands of liters. The capacity selection should consider storage requirements, supply frequency, and spatial constraints. Safety Protection: These tanks require safety protection devices such as pressure relief valves, pressure sensors, and temperature sensors to ensure internal pressure and temperature remain within safe limits. Transportation: Low-temperature CO2 storage tanks can be transported via road, rail, or ship. Proper insulation measures must be taken during transportation to maintain the low-temperature state of the liquid CO2 inside. Safe Operation: Operation of low-temperature CO2 storage tanks requires training and adherence to safety operating procedures. Operators should understand the tank's characteristics and safety considerations to ensure safe and effective operation. Regular Inspection and Maintenance: Regular inspections and maintenance are necessary for low-temperature CO2 storage tanks, including visual inspections, valve and pipeline checks, and pressure relief device checks. Regular maintenance ensures the tank operates normally and safely. The above points cover some knowledge related to low-temperature CO2 storage tanks. When using and operating these tanks, it is essential to follow relevant safety regulations and standards, and consult with experts to ensure safety and effectiveness.

Prior to using the CO2 storage tank, the following preparations must be made: Inspect the tank: Check the tank's exterior for any signs of damage, corrosion, or oil leakage. Ensure the structural integrity and safety of the tank. Inspect valves and pipes: Verify that the tank's inlet and outlet valves and pipe connections are functioning normally, with no leaks or loose fittings. Ensure valves operate smoothly and reliably. Inspect safety accessories: Check that the tank's safety accessories, such as safety valves, pressure sensors, and temperature sensors, are functioning properly. 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. Inspect the pressure relief device: Check that the tank's pressure relief device (e.g., safety valve) is working correctly. Confirm that the set pressure of the relief device meets requirements. Inspect gas quality: Ensure the CO2 gas within the tank meets quality standards, with no impurities or contaminants. Inspect fire protection equipment: Confirm that the fire protection equipment around the tank is in good condition and check that extinguishers, sprinkler systems, etc., are functioning properly. Train operators: Operators should receive training on the characteristics, operational 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 operating procedures and have personnel perform the operations.

Low Temperature Carbon Dioxide Storage Tank Related Knowledge 1. Structure of Low Temperature Carbon Dioxide Storage Tank The low temperature carbon dioxide storage tank typically features a double-layered cylindrical structure. The inner cylinder is made of 6MnDR alloy steel, while the outer cylinder is constructed from Q245R or Q345R pressure vessel steel plate. The piping is made of austenitic stainless steel, and the insulation space is filled with high vacuum pearlite sand or wrapped with multiple layers for thermal insulation. The storage tank is equipped with valves for operation, which are arranged for ease of use. It also includes a pressure gauge and a level gauge for monitoring the internal pressure and liquid level of the low temperature carbon dioxide storage tank. 2. Key Features of Low Temperature Carbon Dioxide Storage Tank (1) The storage tank is equipped with a liquid filling connection for tanker trucks, allowing liquid supply to vaporizers, tanker trucks, and pumps. (2) Both the inner and outer cylinders of the storage tank are equipped with safety devices to ensure safe operation for users. (3) The insulation material of the low temperature carbon dioxide storage tank has been specially treated to extend its vacuum life. Additionally, the tank is fitted with a vacuum gauge for measuring the insulation space vacuum when necessary. 3. Transportation of Low Temperature Carbon Dioxide Storage Tank (1) During road transportation, the storage tank should be securely fastened to the vehicle, traveling at moderate speeds, and collisions with other objects are prohibited. (2) After the storage tank arrives, the unloading personnel should work together with the equipment supervisor to develop a scientific and reasonable unloading plan. 4. Installation of Low Temperature Carbon Dioxide Storage Tank (1) Upon arrival at the installation site, the storage tank can be positioned once the installation conditions are met. During the installation process, collisions and impacts are prohibited, and special attention should be given to the explosion-proof equipment of the outer cylinder and the vacuum valve, which should not be touched. (2) Perform a gas-tightness test on the inner cylinder system of the low temperature carbon dioxide storage tank using nitrogen to the working pressure. After confirming that valves, pipes, flanges, etc., have no leaks, the installation is complete. (3) The installation dimensions of the low temperature carbon dioxide storage tank are specified in the supply materials. When considering liquid filling and emptying with tanker trucks, the vehicle's travel path should be taken into account.

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 choice of capacity 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 meet safety and environmental protection requirements. Sufficient spacing between tanks is necessary for ease of operation and maintenance. - Tank Material: Select appropriate materials for tank construction 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 and temperature sensors, to ensure safe operation. - Leak Protection: Measures should be taken to prevent CO2 leaks, 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 corresponding environmental protection measures. - Regulations and Standards: Compliance with local regulations and standards, including building codes, safety specifications, and environmental protection requirements, is mandatory when planning tanks. - Note: The planning of carbon dioxide storage tanks should be carried out by engineers or relevant institutions to ensure compliance with safety and environmental protection requirements. It is also necessary to consult local authorities for advice and guidance.
