基于虚拟组分的热物理性质计算方法库

Methods for Calculating Thermodynamic Properties of Pseudo-Components

提出的热物理性质计算方法库与文献[1]中的基础物性数据计算方法库组成了一个内置于原油蒸馏过程模型与在线优化软件中的物性数据计算方法库。本文介绍了方法库中的部分计算方法,并通过实例应用,取得了良好的效果。

This part is an aggregation of methods calculating thermodynamic properties of pseudo-components of crude oil. It plays an important role, together with the aggregation of methods calculating physical properties, in the software modeling and optimizing crude distillation based on Computer Integrated Manufacturing Systems. It gives the engineers more chances to choose those methods which fit the special distillation process of their factories most. It gets good results in application to some distillation processes of a refinery.
