Carbon dioxide (CO2) and liquid oxygen (LOX) storage tanks are used for storing different gases, with some physical distinctions: - Physical State: CO2 is a gas at room temperature and requires low temperatures and high pressures to become liquid. LOX is a liquid at room temperature and can remain in liquid form without special conditions. - Storage Temperature: The liquid CO2 storage temperature typically ranges from -40°C to -78.5°C, while the liquid oxygen storage temperature usually ranges from -183°C to -183.15°C. The storage temperature for LOX is lower, necessitating stricter insulation measures. - Storage Pressure: The liquid CO2 storage pressure is generally between 5-20 MPa, whereas the liquid oxygen storage pressure is typically between 0.2-2 MPa. The storage pressure for LOX 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, requiring stricter safety measures. CO2 is relatively safe but can still pose health risks at high concentrations.

Carbon dioxide storage tanks possess the following characteristics: - High-pressure Vessel: Carbon dioxide storage tanks are typically designed as high-pressure vessels, capable of withstanding high pressure. This is because carbon dioxide requires high pressure at room temperature to maintain a liquid state. - High Oxidizing: Carbon dioxide has a high oxidizing nature, which supports combustion. Therefore, when handling and storing carbon dioxide, precautions must be taken to prevent contact to avoid the risk of fire and explosion. - Low-Temperature Storage: Carbon dioxide is in a gaseous state at room temperature but can be compressed into a liquid at lower temperatures. Thus, carbon dioxide storage tanks usually need to have good insulation properties to maintain the low-temperature liquid state of the stored carbon dioxide. - High Density: Liquid carbon dioxide has a high density, allowing for the storage of large amounts of carbon dioxide in a relatively small volume. This makes carbon dioxide storage tanks useful in scenarios requiring substantial carbon dioxide supply. - Safety Valves and Pressure Control: To ensure the internal pressure of the tank remains within a safe range, carbon dioxide storage tanks are usually equipped with safety valves and pressure control devices. These devices monitor and control the internal pressure of the tank to prevent excessive pressure from causing the tank to burst. - Corrosiveness: Carbon dioxide has some degree of corrosiveness, especially in high humidity environments. Therefore, the materials and corrosion prevention measures for the tank need to consider the corrosiveness of carbon dioxide to ensure the tank's durability and safety. These characteristics make carbon dioxide storage tanks widely applicable in many industries, such as the food and beverage industry, fire suppression, and the gas industry. When using carbon dioxide storage tanks, it is necessary to follow relevant safety operation procedures and standards to ensure operational safety.

When selecting a carbon dioxide storage tank support, consider the following factors: Load Capacity: The design and selection of the support should be able to bear the weight and pressure of the tank. The load-bearing capacity of the support should be determined based on the tank's dimensions, weight, and working conditions. Stability: The support should have sufficient stability to prevent the tank from tilting or collapsing during use. The design of the support should take into account the center of gravity location and changes in the tank's center of gravity to provide stable support. Corrosion Resistance: As carbon dioxide has some corrosive properties, the material choice for the support should have good corrosion resistance to prevent corrosion and damage. Installation and Maintenance Convenience: The design of the support should consider ease of installation and maintenance to facilitate the tank's installation, adjustment, and maintenance work. Compliance with Standards and Regulations: The design and selection of the support should comply with relevant standards and regulations, such as Standard GB150 "Steel Pressure Vessels." Additionally, other factors related to the support can be considered, such as cost, reliability, and durability. When selecting a support, consult engineers or consulting companies for advice and guidance.

Carbon dioxide storage tank standard parameters may vary depending on different design and application requirements. Here are some common standard parameters: - Tank Capacity: The capacity of carbon dioxide storage tanks is typically expressed in kiloliters (L) or cubic meters (m). Common capacity ranges vary from a few thousand to tens of thousands of liters. - Working Pressure: The working pressure of carbon dioxide storage tanks is usually around 20 to 25 MPa (megapascals) at room temperature, with the specific pressure determined by application needs and design standards. - Design Temperature: The design temperature of carbon dioxide storage tanks is generally within a low-temperature range, typically -40°C to -60°C, to accommodate the liquefaction and storage requirements of carbon dioxide. - Material: Carbon dioxide storage tanks are commonly made of high-strength steel or alloy materials to withstand stress and loads under high-pressure and low-temperature environments. - Insulation Layer: The tank is internally insulated to reduce heat transfer and liquid evaporation. The insulation layer is typically a multi-layer structure, including thermal insulation materials and an external protective layer. - Safety Valve and Pressure Relief Devices: The tank is equipped with a safety valve and pressure relief devices to control internal tank pressure and prevent overpressure and explosion. - Level Monitoring and Control: The tank is equipped with level monitoring devices to monitor the liquid level inside the tank. Timely monitoring and control of the level ensure that the liquid storage volume within the tank remains within a safe range. It should be noted that specific standard parameters for carbon dioxide storage tanks may vary due to different design standards, application requirements, and manufacturers. When selecting and using carbon dioxide storage tanks, it is important to consider these factors.
