摘要
本文把局部组成概念引入三参数对应态原理中,提出了一个新的过剩焓模型。经用30组物系考核并与UNIFAC、PRG、NRTL及UNIQUAC模型比较,表明新模型关联精度甚高。由二元参数推算多元系,效果也较好。
New correlations of Excess Enthalpy is developed by combining the corresponding state principle and local components concept. The correlations for binary and multi-systems are derived respectively and compared with UNIFAC,PRG,NRTL, UNIQUAC using about 30 groups of data. It is proved that the new correlations are obviously better than other methods compared. And the prediction of multi-systems by binary parameter is also good.
