摘　　要：目前,计算机流程模拟已成为空分装置设计的重要基础。所采用物性数据的准确与否直接影响空分装置设计的可靠性。随着技术的进步,更高精度的多参数物性方程已经逐步应用于空分装置的设计当中。利用自行开发的多参数方程物性包,与传统立方型状态方程的计算结果进行了对比,考察了多参数方程的计算准确性。常用的模拟软件均为用户开发的物性包提供了接口。通过此接口,即可调用物性包用于空分装置的流程模拟计算。The computer process simulation has become an important basis of ASU design.The accuracy of physical property data directly affects the design reliability.Multi-parameter state equation has been gradually applied to the design of ASU.A property package of multi-parameter equation is developed.And the results are compared with traditional cubic equation of state.General simulation software provides the interface for user property method.User property package can be used for process simulation of ASU through the interface.
