Low Temperature Carbon Dioxide Storage Tank Knowledge 1. Structure of Low Temperature Carbon Dioxide Storage Tanks Low temperature carbon dioxide storage tanks typically have a double-layered cylindrical structure. The inner cylinder is made of 6MnDR alloy steel, while the outer cylinder is made of Q245R or Q345R pressure vessel steel plate. The piping is made of austenitic stainless steel, and the insulation space is filled with high-vacuum sintered sand or wrapped with multiple layers of insulation. The storage tanks are equipped with valves for operation, which are arranged for ease of use. Pressure gauges and level indicators are also installed to monitor the pressure and liquid level inside the tank. 2. Key Features of Low Temperature Carbon Dioxide Storage Tanks (1) The storage tanks are equipped with liquid filling connections for trucks, allowing liquid supply to vaporizers, trucks, and pumps. (2) Both the inner and outer cylinders of the storage tanks are equipped with safety devices to ensure safe operation for users. (3) The insulation material of the storage tanks has been specially treated to provide a longer vacuum life. Additionally, the tanks are equipped with vacuum gauges for measuring the insulation space vacuum level when necessary. 3. Transportation of Low Temperature Carbon Dioxide Storage Tanks (1) During road transportation, the storage tank should be securely fastened to the vehicle, travel at moderate speeds, and avoid collisions with other objects. (2) After the storage tank arrives, the unloading crew should work with the equipment supervisor to develop a scientific and reasonable unloading plan. 4. Installation of Low Temperature Carbon Dioxide Storage Tanks (1) Once the storage tank arrives at the installation site, it can be positioned when installation conditions are met. During the installation process, avoid impacts and hits, and pay special attention to the explosion-proof equipment on 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 storage tank using nitrogen to the working pressure. After checking that valves, pipes, flanges, etc., have no leaks, the installation is complete. (3) The installation dimensions of the storage tank are specified in the supply materials. When considering liquid filling and draining with trucks, account for the vehicle's travel path.

Low-temperature carbon dioxide storage tanks are equipment used for storing and transporting low-temperature liquid carbon dioxide (CO2). Here are some knowledge points related to low-temperature carbon dioxide storage tanks: Tank Structure: Low-temperature carbon dioxide storage tanks typically use a double-walled structure, 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 carbon dioxide 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 carbon dioxide storage tanks can be selected based on actual needs, usually ranging from a few thousand to tens of thousands of liters. The capacity selection should consider storage requirements, supply frequency, and spatial limitations. Safety Protection: Low-temperature carbon dioxide storage tanks require safety protection devices, such as pressure relief devices (like safety valves), pressure sensors, and temperature sensors, to ensure internal pressure and temperature remain within safe limits. Transportation Methods: Low-temperature carbon dioxide storage tanks can be transported via road, rail, or ship. Appropriate insulation measures must be taken during transportation to maintain the low-temperature state of the liquid CO2 inside the tank. Safe Operation: The operation of low-temperature carbon dioxide storage tanks requires training and adherence to relevant safety operating procedures. Operators should understand the tank's characteristics and safety precautions to ensure safe and effective operation. Regular Inspections and Maintenance: Low-temperature carbon dioxide storage tanks require regular inspections and maintenance, including visual inspections, valve and pipe checks, and pressure relief device checks. Regular maintenance ensures the tank operates normally and safely. The above points are some knowledge related to low-temperature carbon dioxide storage tanks. When using and operating low-temperature carbon dioxide storage tanks, it is essential to follow relevant safety regulations and standards and consult with experts to ensure safety and effectiveness.

Carbon dioxide storage tank debugging typically includes the following steps and contents: Tank installation check: Inspect the tank's installation location, foundation, and support structure to ensure they meet design requirements, ensuring the tank's stability and safety. Connection pipeline check: Check the connection between the tank and the inlet and outlet pipelines for firmness, and verify that valves and pipelines can be opened and closed normally, ensuring the integrity and normal operation of the pipeline system. Tank cleaning and emptying: Before debugging, the tank must be cleaned and emptied to ensure there are no impurities or residues inside, as well as no other gases or liquids. Tank pressure test: Conduct pressure tests on the tank, including static pressure tests and leak tests. The static pressure test involves increasing pressure to check the tank's sealing and pressure resistance. The leak test is to check for any leakage in the tank and pipeline system. Control system debugging: Debug the tank's control system, including calibration and adjustment of pressure, temperature, and level sensors, to ensure the accuracy and reliability of the control system. Safety system testing: Test the tank's safety system, including functional tests of safety valves, pressure gauges, and level indicators, to ensure the normal operation and response of the safety system. Operating parameter adjustment: Adjust the tank's operating parameters according to actual and process requirements, such as pressure, temperature, and level, to meet process requirements and safe operation. Record and report: Record and organize data, test results, and operation records during the debugging process, generate a debugging report for future reference and management. The above are general steps and contents of carbon dioxide storage tank debugging, and specific debugging tasks may vary according to tank design requirements and application scenarios. When performing debugging tasks, strictly adhere to relevant safety operation procedures and standards to ensure the safety and effectiveness of the debugging process.
