利用Aspen Plus软件对深冷空分工艺流程建立了模拟模型，通过改变工况进行模拟分析，得到产品能耗与氧气体积分数的关系。能耗随氧气体积分数的降低而降低，二者之间的关系式可以拟合为一个4次多项式，为合成氨生产过程的整体优化节能奠定了基础。

A simulation model for cryogenic air separation process is established by using Aspen Plus software.The relationship between the product energy consumption and the volume fraction of oxygen is obtained by simulation under different operating conditions.The product energy consumption decreases with the decrease of the volume fraction of oxygen.The relationship between them can be fitted as a four-order polynomial,which lays the foundation for energy optimization of synthetic ammonia process.
