In recent years, the expansion of low-temperature liquid storage tanks has reached its peak due to the following reasons: 1. Increased energy demand: With economic growth and population increase, the demand for energy is continually rising. Low-temperature liquid storage tanks are primarily used for storing liquefied natural gas (LNG), liquid oxygen (LOX), liquid nitrogen (LIN), and other low-temperature liquid energy sources to meet the growing energy demand. 2. Greenhouse gas emission reduction: These tanks can store and transport liquid carbon dioxide (CO2) for carbon capture and storage (CCS) technologies, reducing greenhouse gas emissions. As environmental protection and climate change awareness grows, the demand for low-temperature liquid storage tanks in the CCS field also increases. 3. Industrial development needs: The application of low-temperature liquid storage tanks in the industrial sector is also on the rise. For instance, in industries such as chemicals, pharmaceuticals, food and beverages, there is a need to store and transport low-temperature liquid raw materials or products, like liquid nitrogen, liquid oxygen, and liquid ethylene. With the development of these industries, the demand for low-temperature liquid storage tanks also grows accordingly. 4. Technological advancement and innovation: In recent years, there have been continuous advancements and innovations in the design, manufacturing, and transportation of low-temperature liquid storage tanks. The application of new materials, optimization of tank structures, and improvements in safety control systems have made these tanks safer and more reliable, further propelling their expansion to a peak. In summary, factors such as increased energy demand, greenhouse gas emission reduction, industrial development needs, and technological advancement and innovation have collectively driven the expansion of low-temperature liquid storage tanks to a peak in recent years. As related industries develop and technology progresses,

When using carbon dioxide tanks, the following safety procedures must be adhered to ensure safety: Tank Operator Training: All operators must receive training to understand the characteristics, operational requirements, and safety measures of carbon dioxide tanks. Training should include safe tank operation, leak handling, emergency response plans, etc. Safety Operating Procedures: Establish and follow relevant safety operating procedures, including tank startup, shutdown, inspection, and maintenance. Operators should operate in accordance with the procedures to ensure safe tank operation. Leak Handling: Develop a leak handling program, including leak detection, emergency shutdown, and isolation of the leak source. Operators should be familiar with the leak handling procedures and able to respond quickly and correctly to leak incidents. Fire Prevention Measures: Carbon dioxide is flammable, so fire prevention measures must be taken when using it. Smoking, open flame operations, or placing flammable materials near the tank are prohibited. Ensure that fire protection equipment around the tank is in good condition and that fire drills are conducted regularly. Waste Gas Emission: When using carbon dioxide tanks, waste gases should be emitted properly to avoid the accumulation of carbon dioxide in enclosed spaces, which can cause asphyxiation and safety risks. Ensure that the waste gas emission system is unobstructed and operating correctly. Regular Inspections and Maintenance: Regularly inspect the tank's appearance, seals, valves, and pipe connections. If any abnormalities or damage are found, they should be repaired or replaced promptly. Also, regularly inspect and maintain the tank's safety valves, pressure sensors, and other accessories. Emergency Response Plans: Develop and implement emergency response plans, including handling leak incidents, evacuation procedures, and first aid measures. Operators should be familiar with the emergency response plans and conduct drills regularly. Monitoring and Alarm Systems: Install and maintain monitoring and alarm systems for the tank.

When filling liquid carbon dioxide into storage tanks, attention should be given to the following aspects: - Safe Operation: Adhere to relevant safety operation procedures and standards during the filling process. Operators must receive training to understand the operational requirements and safety measures of the filling equipment and operate strictly according to the procedures. - Tank Inspection: Before filling, the tank must be inspected to ensure its integrity and safety. Check the tank's appearance, sealing, valves, and pipeline connections, and promptly repair or replace any abnormalities or damages. - Filling Equipment: Select appropriate filling equipment that meets relevant standards and requirements. The filling equipment should have a safe and reliable design and operational functions to ensure the safety and efficiency of the filling process. - Filling Speed Control: Controlling the filling speed is crucial. Excessive filling speed can lead to high tank pressure, increasing safety risks. Control the filling speed based on the tank's capacity and design requirements to ensure safe filling. - Pressure Control: During the filling process, the tank's pressure must be strictly controlled. The filling equipment should be equipped with pressure sensors and safety valves to ensure the internal pressure of the tank remains within a safe range. - Leak Protection: Ensure the sealing of valves and pipelines during the filling process to prevent carbon dioxide leakage. Regularly inspect and replace seals, and promptly address any leak situations. - Monitoring and Recording: Conduct real-time monitoring and record key parameters such as pressure, temperature, and liquid level during the filling process. This helps in promptly identifying abnormalities and making corresponding adjustments. Note that filling carbon dioxide storage tanks should be performed by trained operators and in accordance with relevant safety operation procedures and standards. Seek advice and guidance from knowledgeable professionals.
