摘要
Abstract
The binary interaction parameter among all component was achieved by using UNIQUAC activity coefficient model regression,with references to the data for vapor-liquid equilibrium of sulfolane-aromatic hydrocarbon and liquid-liquid equilibrium of sulfolane-alkane released by literature regarding the 150,000t/a aromatic hydrocarbon extractive and distillation unit of the petrochemical company,Aromatic hydrocarbon extractive and distillation process model was set up by using Aspen plus process simulation software.Less than 2%deviation between simulation data and practical measurement was presented,which showed that the model can accurately calculate the sulfolane-aromatic hydrocarbon extractive and distillation process.In addition,better operation parameter was proposed after testing the influence on separation effect and energy efficiency by parameters such as reflux ratio,feeding benzene content,solvent ratio and co-solvent ratio,etc.关键词
