Review of Physical Properties of High Carbon Dioxide Content

Carbon dioxide from carbon oxide gas fields often includes methane and other gases, which increases the risk of phase changes during pipeline transport. Such changes can pose significant challenges in designing transport systems for stable and efficient flow. Understanding the physical properties of these gas mixtures, such as density, specific heat, viscosity, and compressibility factor, is essential for safe, economic pipeline transport. This paper focuses on both pure CO and a high-CO mixture (90% CO, 10% CH) as working fluids. Using extensive data from databases, we analyze the effects of varying temperatures and pressures on each medium. This detailed analysis aids in optimizing the transport design of high-CO gas fields, providing valuable theoretical support for their effective and safe development, utilization, and economical pipeline transport. The results help engineers manage the complexities associated with phase changes and other physical property variations in pipeline systems, leading to safer, cost-effective, and more efficient operations.
