Carbon dioxide storage tanks' standard specifications can 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 normal temperatures, with specific pressure determined by application needs and design standards. - Design Temperature: The design temperature of carbon dioxide storage tanks is usually within the low-temperature range, generally between -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 interior is equipped with an insulation layer 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 fitted with level monitoring equipment to monitor the liquid level inside the tank. Timely monitoring and control of the level ensure the liquid stored within the tank is within a safe range. - Note 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.

In recent years, the surge in the development of low-temperature liquid storage tanks can be attributed to the following factors: 1. Increased energy demand: As the economy grows and the population expands, the demand for energy continues to rise. Low-temperature liquid storage tanks are primarily used for storing liquefied natural gas (LNG), liquid oxygen (LOX), liquid nitrogen (LIN), and other low-temperature liquid energy sources to meet the growing energy needs. 2. Greenhouse gas emission reduction: These tanks can store and transport liquid carbon dioxide (CO2) for carbon capture and storage (CCS) technologies, reducing greenhouse gas emissions. With growing concern for environmental protection and climate change, the demand for low-temperature liquid storage tanks in the CCS field has also increased. 3. 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 is a need to store and transport low-temperature liquid raw materials or products, such as liquid nitrogen, liquid oxygen, and liquid ethylene. As these industries develop, so does the demand for low-temperature liquid storage tanks. 4. 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 peak development. In summary, factors such as increased energy demand, greenhouse gas emission reduction, industrial development needs, and technological advancement and innovation have collectively driven the peak development of low-temperature liquid storage tanks in recent years. As related industries develop and technology progresses,
