Design requirements for carbon dioxide storage tanks typically include the following aspects: Pressure Vessel Design: Carbon dioxide storage tanks are usually designed as high-pressure vessels capable of withstanding high pressures. The design must comply with relevant standards and specifications, such as Standard GB150 "Steel Pressure Vessels." Material Selection: The choice of materials for the tank should consider the properties of carbon dioxide, such as high pressure, high oxidizability, and corrosiveness. Common materials include carbon steel and stainless steel, with selection based on specific working conditions and requirements. Safety Valve and Pressure Control: The tank should be equipped with a safety valve and pressure control devices to ensure internal pressure remains within a safe range. The safety valve should be selected according to design requirements and regularly inspected and tested to ensure proper operation. Insulation Performance: Since carbon dioxide needs to remain in a liquid state at low temperatures, the tank should have good insulation properties to prevent excessive evaporation of liquid carbon dioxide and energy loss. The selection and design of insulation materials and layers should consider working temperatures and environmental conditions. Leak Detection and Alarm: The tank should be equipped with leak detection devices and alarm systems, as well as corresponding monitoring equipment. These devices can detect leaks in a timely manner and trigger alarms, allowing for appropriate measures to be taken. Structural Strength and Stability: The structural design of the tank should have sufficient strength and stability to withstand internal pressure and external loads. The structural design must comply with relevant standards and specifications, such as Standard GB12337 "Design Code for Pressure Vessels." Safe Operation and Maintenance: The design of the tank should take into account the ease of safe operation and maintenance, such as the placement of manholes, inspection openings, and drain ports.

Carbon dioxide (CO2) and liquid oxygen (LOX) storage tanks are equipment used for storing different gases. They have some differences in physical properties: - Physical State: CO2 is a gas at room temperature and requires low temperatures and high pressure to convert to a liquid. LOX is a liquid at room temperature and can remain in liquid form without special conditions. - Storage Temperature: The liquid CO2 storage temperature is typically between -40°C and -78.5°C, while the liquid oxygen storage temperature is usually between -183°C and -183.15°C. The storage temperature of liquid oxygen is lower, requiring more stringent insulation measures. - Storage Pressure: The liquid CO2 storage pressure is generally between 5-20 MPa, while the liquid oxygen storage pressure is typically between 0.2-2 MPa. The storage pressure of liquid oxygen is lower. - Density: The density of liquid CO2 is approximately 0.8 g/cm³, while the density of liquid oxygen is about 1.14 g/cm³. The density of liquid oxygen is greater. - Safety: LOX has a high oxygen content, making it highly flammable and oxidizing, necessitating stricter safety measures. CO2 is relatively safe but can still be harmful to humans at high concentrations.

Carbon dioxide storage tanks are devices used for storing and transporting carbon dioxide gas, with their principle based on the working principle of pressure vessels and the physical properties of carbon dioxide. Pressure Vessel Principle: Carbon dioxide storage tanks are pressure vessels capable of withstanding the pressure of the internal gas. They are typically made of high-strength materials such as steel. The design and structure of the tank can withstand high pressure, ensuring safe storage and transport of the gas. Compressed Gas Storage: Carbon dioxide is a gas at room temperature but can be compressed into a liquid under high pressure. Storage tanks use high pressure to compress the gas into a liquid, achieving a higher storage density. The volume occupied by liquid carbon dioxide is relatively small, allowing for more gas to be stored. Level Control: The storage tanks are equipped with level control systems to monitor and control the level of liquid carbon dioxide. These systems usually include level sensors and control valves, ensuring the level within the tank remains within a safe range. Pressure Control: The tanks also have pressure control systems to monitor and control the gas pressure inside. These systems typically include pressure sensors and safety valves, ensuring the pressure within the tank remains within a safe range, avoiding damage or safety risks from excessive or low pressure. Through these principles, carbon dioxide storage tanks can safely store and transport carbon dioxide gas to meet the needs of various fields, such as food processing, beverage manufacturing, and fire extinguishing. When using carbon dioxide storage tanks, it is necessary to follow relevant safety operation procedures and guidelines to ensure safe operation and use.
