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), with common capacity ranges ranging 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 normal temperatures, with specific pressure determined by application needs and design standards. - Design Temperature: The design temperature of carbon dioxide storage tanks usually falls within the low-temperature range, generally between -40°C and -60°C, to accommodate the liquefaction and storage requirements of carbon dioxide. - Material: Carbon dioxide storage tanks are commonly made from high-strength steel or alloy materials to withstand stress and loads under high pressure and low-temperature environments. - Insulation Layer: The interior of the tank is equipped with an insulation layer to reduce heat transfer and liquid evaporation. The insulation layer typically consists of multiple layers, including thermal insulation materials and an outer protective layer. - Safety Valve and Pressure Relief Device: Tanks are equipped with safety valves and pressure relief devices to control internal tank pressure and prevent overpressure and explosions. - Level Monitoring and Control: Tanks are fitted with level monitoring equipment to monitor the liquid level within the tank. Timely monitoring and control of the level ensure that the liquid stored in 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.

When storing carbon dioxide tanks, the following requirements must be adhered to ensure safety and effectiveness: Ventilation: Tanks should be stored in well-ventilated areas to prevent the accumulation of carbon dioxide gas. Ensure adequate air circulation around the tank to avoid gas buildup and asphyxiation risks. Fire and Explosion Prevention: Keep tanks away from fire sources, high-temperature areas, and flammable materials. Avoid open flame operations near the tank to prevent fire and explosion risks. Avoid Direct Sunlight: Store tanks in locations shielded from direct sunlight to prevent overheating and pressure increase. Direct sunlight can raise tank temperatures, increasing the risk of leaks and explosions. Prevent Mechanical Damage: Keep tanks away from machinery and heavy objects to avoid collisions and damage. Mechanical damage may lead to tank leaks or ruptures, causing safety hazards. Labeling and Warning Signs: Clearly mark tanks with information on the stored gas type and pressure. Set up warning signs around the tank to alert personnel to its presence and related safety precautions. Regular Inspections: Conduct regular inspections of the tank's appearance, valves, and connections to ensure they are undamaged. Take prompt corrective actions if any abnormalities are found. Storage Capacity Control: Control the storage capacity of the tank to prevent exceeding the rated capacity. Overfilling may lead to excessive tank pressure, increasing safety risks. Storage Records: Keep records of the tank's usage, including filling dates, quantities, and inspection records. Regularly inspect and maintain the tank, and retain relevant records. Note that specific storage requirements may vary depending on tank types and applications. When storing carbon dioxide tanks, operate according to relevant regulations and standards, and consult with experts to ensure safety and effectiveness.
