1.What types are carbon dioxide storage tanks classified into according to volume, and what are their typical uses respectively?

Volume Range (cubic meters)	Type	Typical Applications
0.5~5 m³	Small storage tank	Laboratories, food processing (e.g., beer carbonation), medical oxygen production support, small fire protection systems, etc.
10~50 m³	Medium storage tank	Industrial gas supply, beverage filling production lines, chemical reactor supporting, medium and small cold storage, etc.
100~500 m³	Large storage tank	Power plant carbon capture projects, large chemical parks, food cold chain logistics centers, sewage treatment plants, etc.
Over 1000 m³	Ultra-large storage tank	Liquefied carbon dioxide (LCO₂) transportation hubs, carbon dioxide enhanced oil recovery (EOR) projects, marine liquid carbon dioxide storage tanks, etc.

2.Why can’t carbon dioxide storage tanks be left empty for a long time?

Safety Risks

Carbon dioxide is a high-pressure gas that remains in a liquid state only when a certain pressure is maintained inside the storage tank. If carbon dioxide in the tank is continuously released into the atmosphere over time, the pressure inside the tank will decrease, potentially causing structural rupture or explosion of the tank and other safety hazards.

Resource Waste

Carbon dioxide is a valuable resource with wide applications in industry and other fields. Long-term emptying of carbon dioxide storage tanks will lead to waste of resources, which is inconsistent with the principles of sustainable development.

Environmental Impact

Carbon dioxide is a greenhouse gas. Long-term empty release of carbon dioxide will increase the concentration of carbon dioxide in the atmosphere, exacerbating climate change and environmental problems.

3.Before using a carbon dioxide storage tank, the following preparatory work is required:

Tank Inspection

Check the appearance of the tank for integrity, ensuring there is no obvious damage, corrosion, or oil leakage. Verify the structural integrity and safety of the tank.

Valve and Pipeline Inspection

Inspect the inlet/outlet valves of the tank and pipeline connections for normal operation, with no signs of leakage or looseness. Ensure that the valves operate flexibly and reliably.

Safety Accessory Inspection

Check the safety accessories of the tank, such as safety valves, pressure sensors, temperature sensors, etc., to ensure they are functioning properly. Verify that their set parameters meet the requirements.

Liquid Level Measurement System Inspection

Check the accuracy and reliability of the liquid level measurement system. Calibrate the liquid level sensor to ensure accurate liquid level measurement.

Pressure Relief Device Inspection

Inspect the pressure relief device (such as a safety valve) of the tank to ensure it is functioning normally. Verify that the set pressure of the pressure relief device meets the requirements.

Gas Quality Check

Ensure that the quality of the carbon dioxide gas in the tank meets the requirements, with no impurities or contaminants.

Fire Protection Facilities Inspection

Ensure that the fire protection facilities around the tank are in good condition, and check that fire extinguishers, sprinkler systems, etc., are operating normally.

Operator Training

Operators should receive training to understand the characteristics, operation requirements, and safety measures of the carbon dioxide storage tank. The training content should include safe operation of the tank, leakage handling, emergency measures, etc.
