- Regular Inspections: Conduct regular checks of the tank's exterior, internal linings, valves, and pipe connections. Be mindful of signs of corrosion, cracks, or oil leaks.
- Cleaning and Draining: Regularly clean the interior of the tank to remove accumulated debris and sediment. Also, regularly drain the tank to remove liquid and gas impurities.
- Corrosion Prevention: The outer shell and internal lining of low-temperature liquid storage tanks should be treated with corrosion prevention. Regularly inspect and maintain the integrity of the protective coating or paint to ensure effectiveness.
- Temperature and Pressure Control: Maintain the tank's temperature and pressure within the design specifications. Avoid extremes that could damage the tank.
- Safety Equipment Checks: Inspect the tank's safety equipment, such as safety valves, pressure and temperature sensors, to ensure they are functioning properly. Verify that their set parameters meet requirements.
- Level Measurement System Maintenance: Regularly check and calibrate the level measurement system to ensure accuracy and reliability. Clean or replace level sensors as needed.
- Fire Prevention Measures: Fire prevention is crucial for low-temperature liquid storage tanks. Ensure that fire protection equipment around the tank is in good condition and conduct regular fire drills.
- Regular Assessments and Monitoring: Regularly assess and monitor the tank, including structural integrity, corrosion, and safety. Take appropriate maintenance and repair actions based on assessment results.
- Operator Training: Operators should be trained to understand the characteristics, operation requirements, and safety measures of low-temperature liquid storage tanks. Training should include safe operation, leak management, and emergency procedures.
When using carbon dioxide tanks, the following points should be noted:
Safety Operation: Prior to operating a carbon dioxide tank, it is mandatory to be familiar with and adhere to the relevant safety operating procedures and guidelines. Ensure that operators have received necessary training and understand the tank's working principle, operational procedures, and emergency measures.
Tank Inspection: Regularly inspect the external and internal conditions of the carbon dioxide tank, including checking for corrosion, leaks, and welds on the tank walls. If any abnormalities or damage are found, take immediate corrective or replacement actions.
Tank Pressure Control: Maintain the internal pressure of the tank within a safe range. Monitor and control the tank's pressure to avoid damage or safety risks from excessive or low pressure.
Fire Prevention Measures: Carbon dioxide is a flammable gas, and fire prevention measures must be observed during use. Avoid open flame work near the tank and ensure there are no flames in the surrounding environment.
Leakage Handling: In the event of a carbon dioxide leak, appropriate emergency measures should be taken immediately. Quickly notify relevant personnel, ensure a safe evacuation, and take actions to prevent the spread of the leak.
Tank Maintenance: Regularly perform maintenance and upkeep on the tank, including cleaning, lubrication, and corrosion prevention. Follow the manufacturer's recommendations and guidelines to ensure the tank operates normally and has a long service life.
Compliance: Adhere to local regulations, standards, and specifications to ensure the tank's design, manufacturing, installation, and use meet the corresponding requirements.
It is crucial to strictly follow safety operating procedures when using carbon dioxide tanks and to cooperate with relevant personnel to ensure the tank's safety and reliability.

In summary, carbon dioxide storage tanks have characteristics such as high-density storage, safety and reliability, environmental and renewable, and multiple application fields, making them an important equipment for storing and supplying carbon dioxide gas.
In recent years, the expansion of low-temperature liquid storage tanks has reached its peak due to several factors:
- Increased energy demand: As the economy grows and the population expands, there's a rising need for energy. Low-temperature liquid storage tanks are primarily used for storing liquefied natural gas (LNG), liquid oxygen (LOX), and liquid nitrogen (LIN) to meet the growing energy requirements.
- Reduction of greenhouse gas emissions: These tanks can store and transport liquid carbon dioxide (CO2), used in carbon capture and storage (CCS) technology to decrease greenhouse gas emissions. With heightened concern for environmental protection and climate change, the demand for low-temperature liquid storage tanks in the CCS field has also increased.
- Industrial development needs: The application of low-temperature liquid storage tanks in the industrial sector is also on the rise. For instance, in industries like chemicals, pharmaceuticals, food and beverages, there's a need for storing and transporting low-temperature liquid raw materials or products such as liquid nitrogen, liquid oxygen, and liquid ethylene. As these industries grow, so does the demand for low-temperature liquid storage tanks.
- 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, the need for greenhouse gas reduction, industrial development, and technological advancements and innovations have collectively driven the peak expansion of low-temperature liquid storage tanks in recent years.
