聚酯反应过程中汽液平衡的计算

CALCULATION OF THE VLE IN PET REACTION PROCESS

利用聚合物ＮＲＴＬ模型对酯化反应器中聚合物－ 乙二醇－ 水体系进行分析，找出了适合仪化公司聚酯生产线的二元组分参数。计算表明，得出的参数真实地反映了酯化反应器内的汽液相关系。

This paper used Polymer NRTL property model to analyse the VLE in polymer EG H 2O ternary system, and found out binary parameters proved to be suitable for the company′s process. Vapor flow rate and components can be calculated by using these parameters without estimations.
