COMPUTER-AIDED DEVELOPMENT OF AZEOTROPIC DISTILATION PROCESSES

(1)在个人计算机上建立了用于计算机辅助开发共沸蒸馏系统的原型系统。(2)数据库和准数据库。建立了一个共沸数据库，其中有纯材料的1706个数据，二元共沸物的18279个数据和三元共沸物的921个数据，并建立了用于估算纯物质、二元共沸物和三元共沸物的缺陷性数据的准数据库。(3)系统的性能检查为了检查系统的性能，选择了对非均相二元共沸物共沸精馏的夹带剂进行了选择，并与现有工艺的夹带剂进行了比较。(4)非均相三元共沸物的扩展对系统进行了改进，使之能够寻找非均相三元共沸物共沸精馏过程中的夹带剂。

(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.
