Carbon dioxide cryogenic pipelines are pipelines used to transport low-temperature carbon dioxide, and their main functions include:
Storage and reduction of transportation costs
CO2 cryogenic pipelines can be connected to CO2 storage facilities to store CO2 underground or in containers for environmental protection and climate change mitigation. At the same time, the use of pipelines to transport CO2 can reduce transportation costs and increase efficiency, reducing environmental impact, with economic and sustainable advantages.
Applications in multiple industries
CO2 cryogenic pipes can be used in a variety of applications, such as the food and beverage industry, the pharmaceutical sector, and oil field extraction. In the food and beverage industry, carbon dioxide can be used as a driving agent or shielding gas in food and beverages, such as in the manufacture of sparkling beverages and beer, and in the extension of the shelf life of food. In the pharmaceutical field, carbon dioxide can also be used in medical applications, such as providing respiratory therapy to patients, and high concentrations of carbon dioxide can also be used to sterilize and kill biological contaminants. Injecting carbon dioxide into the wellhead during oil field extraction can increase crude oil production while reducing environmental pollution.
Environmental advantages
Compared with the commonly used ammonia and freon working fluids, carbon dioxide has a very low ODP (ozone attenuation index) and GWP (greenhouse impact index), and has little impact on the environment. Therefore, it is of great practical significance to develop low-temperature heat pipes with carbon dioxide as working fluid, which are suitable for heat conduction in the temperature range of -50~0°C, and are expected to achieve long-range heat conduction, which plays an important role in low-temperature superconductivity, cold storage and other fields.
To sum up, carbon dioxide cryogenic pipelines play an important role in many fields, with the advantages of environmental protection, economy and efficiency.
