摘要
Abstract
In order to accurately predict the solubility of elemental sulfur in acid gas mixture using Chrastil's association model,based on the experimental data of the solubility of elemental sulfur in acid gases in the related literature,the sulfur solubility prediction effects of the Chrastil model whose coefficients are obtained by two kinds of fitting methods were analyzed,and the results show that,the Chrastil model coefficients obtained by the first kind of fitting method can not used for the prediction of the sulfur solubility,the Chrastil model coefficients obtained by the second kind of fitting method can be used,but the prediction accuracy is very low. For this reason,the second kind of fitting method is improved. The application results of cases show that,in the temperature and pressure ranges in this pa-per,the prediction accuracy of the Chrastil model whose coefficients are calculated by the improved fitting method is high,and its aver-age relative fitting error is less than 5%.关键词
