The reasons for regular inspections of low-temperature liquid carbon dioxide storage tanks are to ensure their safety performance and normal operation. Due to the storage tanks' exposure to low temperatures and high pressures, certain safety risks are present, such as leaks and structural fractures. Regular inspections help to identify potential issues early, allowing for timely repairs or maintenance to ensure safe operation. The specific inspection frequency should be determined according to relevant regulations and standards, and it is generally recommended to conduct routine inspections and maintenance. Typically, the time interval for regular inspections of low-temperature liquid carbon dioxide storage tanks is between 1 to 3 years, with the exact interval potentially varying based on factors such as usage, age, and design standards. The content of regular inspections usually includes visual inspections of the tank, checks of valves and connections, leak detection, and pressure tests. Additionally, regular inspections and maintenance of the tank's insulation should also be performed to ensure its insulating performance. It is important to note that the specific inspection frequency and content should be determined based on local laws, standards, and the manufacturer's recommendations. Inspections should be carried out by qualified personnel, and results and maintenance records should be documented for tracking and managing the tank's safety performance.

The working principle of carbon dioxide storage tanks involves the compression and liquefaction of carbon dioxide. Here is a brief description of the working principle of carbon dioxide storage tanks: Compression: Carbon dioxide gas is first compressed to a higher pressure by a compressor. This process compresses the gas into a high-pressure state, enabling it to be converted into a liquid. Cooling: The compressed carbon dioxide gas enters a cooler, where it is rapidly cooled through a cooling agent or system within the cooler. This process cools the gas below its boiling point, converting it into a liquid. Storage: The cooled carbon dioxide liquid is stored in sealed tanks, which typically have insulation to reduce the evaporation of liquid carbon dioxide and maintain a low temperature. The pressure inside the tank is maintained within a certain range to ensure stable storage of the liquid carbon dioxide. Supply: When carbon dioxide is needed, it can be extracted from the tank through valves and piping systems. By controlling the opening and flow of the valves, liquid carbon dioxide can be supplied to the required equipment or system. It should be noted that the working principle of carbon dioxide storage tanks may vary depending on specific design and manufacturing. When using carbon dioxide storage tanks, follow the operation manual and safety guidelines, and cooperate with local regulatory agencies and personnel to ensure the safety and reliability of the tank.

In recent years, the peak development of low-temperature liquid storage tanks can be attributed to the following factors: 1. Increasing energy demand: As the economy grows and the population expands, the demand for energy continues to rise. 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 needs. 2. Greenhouse gas emission reduction: These tanks can store and transport liquid carbon dioxide (CO2) for carbon capture and storage (CCS) technologies, helping to reduce greenhouse gas emissions. With growing concerns for environmental protection and climate change, the demand for low-temperature liquid storage tanks in the CCS field has also increased. 3. Industrial development needs: The application of low-temperature liquid storage tanks in the industrial sector is also on the rise. For instance, in chemical, pharmaceutical, food and beverage industries, there is a need to store and transport low-temperature liquid raw materials or products, such as liquid nitrogen, liquid oxygen, and liquid ethylene. As these industries develop, the demand for low-temperature liquid storage tanks also increases 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 peak development. In summary, factors such as increasing energy demand, greenhouse gas emission reduction, industrial development needs, and technological advancement and innovation have collectively driven the peak development of low-temperature liquid storage tanks in recent years.
