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.
