估算低压纯气体黏度方法的评价及改进
Evaluation and Method Improvement of Viscosity Estimation of Low-Pressure Pure Gases
摘要
Abstract
Viscosity is an important property of organic compounds, which is an important parameter for chemical process simulation and optimization. There are experimental viscosity values available in literature, but many viscosity data are not easily acquirable by experiments. A variety of methods for estimating viscosity of organic compounds were summarized, and principles, advantages/disadvantages and applications of the Reichenberg method, Chung method, Lucas method and Golubev method were discussed. The results from using these methods to calculate 100 randomly selected compounds were compared. The Chung method is found a more accurate method to estimate viscosity. Moreover, seven group contribution values for the Reichenberg method and 18 k values of acid compounds for the Chung method are added, and the application range of these methods can be expanded.关键词
