采用白杨Plus对工业裂解炉中乙烷热裂解反应动力学进行了研究。辐射盘管被建模为一维活塞流反应器，其中乙烷进行蒸汽裂解。提出了一种改进的乙烷裂解反应方案，预测了乙烷裂解的产物分布，并与工业数据进行了比较，验证了模型的有效性。此外，该模型被用来评估各种工艺参数，包括盘管出口温度，停留时间，和蒸汽与乙烷的比例，对裂解气的产率和组成的影响。
The kinetics of ethane thermal cracking in industrial pyrocrackers was investigated using Aspen Plus. The radiant coils were modeled as a 1D plug-flow reactor in which ethane is subjected to steam cracking. An improved reaction scheme for ethane cracking was proposed to predict product distribution which was compared with industrial data to validate the model. Further, the model was used to assess the effects of various process parameters, including coil outlet temperature, residence time, and steam-to-ethane ratio, on yield and composition of the cracked gas.
