Abstract: The key facility for producing ethyl acetate is a complex distillation column with a reboiler performing as an esterification reactor. An algorithm, employing Block-Hegners algorithm together with a relaxation method has been taken for the simulation of this reactor-three phase distillation column system. More stable convergence has thus been obtained. Furthermore, by using the sparse matrix approach, less storage requirements are needed, allowing the problem to be solved in a microcomputer. Twelve case studies are conducted using this algorithm. Calculated results are compared with data measured in an operating plant.

摘要： 本文在Block算法的基础上结合使用松弛法对酯化反应一粗酯分离系统进行了反应-三相恒沸精馏的计算机模拟计算.这种算法与Block算法比较不但收敛稳定 而且由于在程序上采用了稀疏矩阵的处理技术,便于在微机上实现.用本算法,对十二种不同的操作条件进行了模拟计算,并将计算结果与工厂提供的数据作了比较.
