COMPUTER-AIDED DEVELOPMENT OF AZEOTROPIC DISTILATION PROCESSES

(1)原型系统已在个人计算机上制作了用于共沸蒸馏系统计算机辅助开发的原型系统。(2)建立了纯材料共沸数据库1706个，二元共沸数据库18279个，三元共沸数据库921个，并建立了纯材料、二元共沸体和三元共沸体缺失数据估计准数据库。为了考察体系的性能，对利用非均相二元共沸物进行共沸蒸馏的夹带剂进行了选择，并将所得到的夹带剂与现有工艺的夹带剂进行了比较。(4)向非均相三元共沸物的扩展该系统已得到改进，能够在利用非均相三元共沸物的共沸蒸馏过程中寻找夹带剂。

(1) Proto-type systemProto-type system for computer-aided development of azeotropic distilllation systems has been made on a personal computer.(2) Database and quasi-databaseAn azeotropic database with 1,706 data on pure materials, 18,279 data on binary azotropes and 921 data on ternary azeotropes has been made and quasi-databases have been made for estimating lacked data on pure materials, binary azeotropes and ternary azeotropes.(3) Examination of performance of the systemIn order to examine the performance of the system, selection of the In order to examine the performance of the system, selection of the entrainers for azeotropic distilllation utilizing heterogeneous binary azeotropes has been carried out and the obtained entrainers have been compared with those of existing processes.(4) Extention to heterogeneous ternary azeotropesThe system has been improved to be able to search for the entrainers for azeotropic distilllation processes utilizing heterogeneous ternary azeotropes.
