本软件系统包括4个子系统:①平衡数据关联子系统-含Van Laar、Margules、NRTL、UNIQUAC和Wilson模型以及Antione常数回归方程;②精馏子系统-含间歇精馏、普通精馏和萃取精馏;③液液萃取子系统-包括无水和含水溶剂体系;④数据库子系统-建成bpd.mdb数据文件,具有查询和管理各种烷烃、芳烃和溶剂等基础物性的功能。软件系统采用VB设计,界面友好,操作简便,可用于汽液和液液平衡数据模型参数的关联以及多元多级汽液和液液平衡级的分离计算。
The software system consists of four subsystems: ① balanced data related subsystems - including Van Laar, Margules, NRTL, UNIQUAC and Wilson models and Antione constant regression equation; ② sub-distillation system - containing batch distillation, ordinary distillation and extraction of fine Distillation; ③ liquid-liquid extraction subsystem - including anhydrous and aqueous solvent system; ④ database subsystem - built bpd.mdb data file, with the query and management of various alkanes, aromatics and solvents and other basic physical functions. The software system adopts VB design, the interface is friendly and easy to operate. It can be used to correlate the parameters of vapor-liquid and liquid-liquid equilibrium data model and to separate and calculate the multi-level vapor-liquid and liquid-liquid equilibrium.
