Water pressure testing of CO2 storage tanks is a common quality inspection method used to verify the tank's sealing and pressure resistance. Below are the general steps for conducting a water pressure test on CO2 storage tanks: Preparation: Ensure the tank interior is clean and the tank is empty. Check the tank's valves, pipes, and connections to ensure they are sealed properly. Filling with Water: Fill the tank with water, using tap water or other clean sources. Ensure even water filling to avoid bubbles or dead spots. Applying Pressure: Use a pressure pump or other pressure device to gradually increase water pressure until it reaches the predetermined test pressure. The test pressure is typically determined based on the tank's design requirements and relevant standards. Maintaining Pressure: After reaching the test pressure, hold it for a period, usually 15-30 minutes. During this time, observe for any leakage in the tank and check for leaks in the valves and connections. Pressure Release: Release the water pressure inside the tank, ensuring a slow and even release to avoid sudden pressure release causing shock. Inspection and Evaluation: After pressure release, inspect the tank's exterior and interior for any leakage. Evaluate the test results to ensure the tank's sealing and pressure resistance meet requirements. It is important to note that when conducting water pressure tests, safety operating procedures and standards should be followed to ensure safety and reliability during the testing process. Depending on the tank's design and usage requirements, other types of tests can be conducted, such as gas pressure tests, ultrasonic inspections, etc., to comprehensively assess the tank's quality and performance. Seek advice and guidance from experts.

Carbon Dioxide Applications in the New Energy Field Carbon Capture and Storage (CCS): This technology reduces CO2 emissions by capturing CO2 from industrial sources and storing it underground, preventing its release into the atmosphere. It aids in decreasing greenhouse gas emissions and mitigating climate change. Carbon Utilization: CO2 can be utilized to produce valuable chemicals and fuels. For instance, through CO2 catalytic conversion technology, CO2 can be transformed into fuels like ethanol, which are either combustible or raw materials for chemicals. This carbon utilization technique helps reduce reliance on traditional fossil fuels and promotes sustainable energy development. Carbon Dioxide Batteries: Carbon Dioxide batteries are a new battery technology that uses CO2 as the battery's electro material. By converting CO2 into electrical energy, these batteries can serve as a sustainable energy storage solution, contributing to the advancement of electric vehicles and renewable energy. Carbon Dioxide Photocatalysis: This technology uses solar energy to convert CO2 into useful chemicals. By employing photocatalysts, CO2 and water can be transformed into combustible gases or organic compounds, achieving the resource utilization of CO2. These applications aim to reduce CO2 emissions, enhance energy efficiency, and promote sustainable energy development. However, these technologies are still in development and research, requiring further technical breakthroughs and practical verification.

During routine inspections of carbon dioxide storage tanks, follow these steps: - Visual Inspection: Check for any visible damage, corrosion, or oil leakage on the tank's exterior. Pay attention to any abnormalities in the tank shell, valves, and pipe connections. - Valve and Pipe Inspection: Verify that the tank's inlet and outlet valves and pipe connections are functioning properly, and there are no leaks or loose fittings. Ensure valves operate smoothly and reliably. - Pressure Relief Device Inspection: Check that the tank's pressure relief devices (such as safety valves) are operating correctly. Confirm that the set pressure of the relief devices meets requirements. - Level Measurement System Inspection: Assess the accuracy and reliability of the level measurement system. Calibrate the level sensors to ensure accurate level measurements. - Pressure and Temperature Inspection: Check that the tank's pressure and temperature sensors are working properly. Verify the accuracy of pressure and temperature measurements. - Safety Equipment Inspection: Inspect the tank's safety equipment, such as safety valves, pressure sensors, and temperature sensors, to ensure they are functioning correctly. Confirm that their set parameters meet requirements. - Fire Protection Equipment Inspection: Ensure that fire protection equipment around the tank is in good condition and check that extinguishers, sprinkler systems, etc., are functioning properly. - Liquid and Gas Quality Inspection: Ensure that the liquid and gas carbon dioxide in the tank meets quality requirements, with no impurities or contaminants. - Record and Report: Document the date of the inspection, the inspection items, identified issues, and actions taken. Submit inspection reports to relevant departments or management as needed. These are general steps for routine inspections of carbon dioxide storage tanks. Specific procedures should be adapted to the tank's characteristics and requirements. When conducting inspections, follow relevant safety operating procedures and have trained personnel perform the operations.

1.相关知识 about Low-Temperature Carbon Dioxide Storage Vessels The low-temperature carbon dioxide storage vessel typically features a double-walled cylindrical structure. The inner cylinder is made of 6MnDR alloy steel, while the outer cylinder is constructed from Q245R or Q345R pressure vessel steel plates. The piping is made of austenitic stainless steel, and the insulation space is filled with high-vacuum sintered sand or layered insulation. The storage vessel is equipped with valves for operation, which are strategically placed for ease of use. It also features a pressure gauge and a level gauge for monitoring the pressure and liquid level inside the vessel. 2.Main Features of Low-Temperature Carbon Dioxide Storage Vessels (1) The storage vessel is fitted 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 vessel are equipped with safety devices to ensure safe operation for the user. (3) The insulation material of the storage vessel is specially treated to provide a longer vacuum life. Additionally, the vessel is equipped with a vacuum gauge for measuring the insulation space vacuum level when necessary. 3.Shipping of Low-Temperature Carbon Dioxide Storage Vessels (1) During road transportation, the storage vessel must be securely fastened to the vehicle, travel at moderate speeds, and is strictly prohibited from colliding with other objects. (2) After the storage vessel 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 Vessels (1) Once the storage vessel arrives at the installation site, it can be placed when the installation conditions are met. During the installation process, collisions and impacts are prohibited, and special attention should be paid to the explosion-proof equipment on the outer cylinder and the vacuum valve, which must not be touched. (2) Perform a gas-tightness test on the inner cylinder system of the storage vessel using nitrogen to the working pressure. After checking that valves, pipes, flanges, etc., are leak-free, the installation is complete. (3) The installation dimensions of the storage vessel are as specified in the supply documents. When considering filling and emptying liquids with tanker trucks, the vehicle's travel route should be taken into account.
