二氧化碳管道输送过程中会发生热交换。某种物质每单位质量的温度升高（降低）1℃，吸收（释放）的热量称为该物质的比热容。热交换量与传输介质的比热容有很大的关系。因此，研究二氧化碳比热容的变化对研究二氧化碳管道输送规律具有重要的现实意义。Hysys用于模拟纯二氧化碳的比热容随温度和压力的变化，

Heat exchange occurs during the transportation of carbon dioxide through pipelines. When the temperature of a substance increases (decreases) by 1 ℃ per unit mass, the heat absorbed (released) is called the specific heat capacity of the substance. The heat exchange capacity is closely related to the specific heat capacity of the transmission medium. Therefore, the study of the change of carbon dioxide specific heat capacity is of great practical significance to the study of carbon dioxide pipeline transport law. Hysys is used to simulate the change of specific heat capacity of pure carbon dioxide with temperature and pressure,

Heat exchange will occur in the process of carbon dioxide pipeline transportation. The specific heat capacity of a substance is called the heat absorbed (released) when its temperature per unit mass increases (decreases) by 1℃. The heat exchange capacity has a great relationship with the specific heat capacity of the transmission medium. Therefore, it is of great practical significance to study the change of specific heat capacity of carbon dioxide for studying the law of carbon dioxide pipeline transportation.
