二氧化碳在管道输送过程中会发生热量的交换，单位质量的某种物质温度升高（降低）1℃，所吸收（放出）的热量叫做物质的比热容，而交换热量的多少和输送介质的比热容有很大的关系，因此研究二氧化碳比热容变化情况对研究管道输送二氧化碳的规 律有很大的实际意义。利用Hysys模拟纯二氧化碳的比热容随着温度和压力的变化情况，

Heat exchange will occur in the process of carbon dioxide pipeline transportation. The temperature of a certain substance per unit mass increases (decreases) by 1 ℃, and the heat absorbed (released) is called the specific heat capacity of the substance. The amount of heat exchanged has a great relationship with the specific heat capacity of the transmission medium. Therefore, studying the change of specific heat capacity of carbon dioxide has great practical significance for studying the law of carbon dioxide pipeline transportation. Hysys is used to simulate the change of specific heat capacity of pure carbon dioxide with temperature and pressure,

Carbon dioxide will exchange heat in the process of pipeline transportation. When the temperature of a substance per unit mass increases (decreases) by 1℃, the heat absorbed (released) is called the specific heat capacity of the substance, and the amount of heat exchanged has a great relationship with the specific heat capacity of the transportation medium. Therefore, it is of great practical significance to study the changes of the specific heat capacity of carbon dioxide for pipeline transportation. Hysys is used to simulate the change of specific heat capacity of pure carbon dioxide with temperature and pressure.
