Abstract

Simulation of reactive distillation by using special engineering software is promising way to its design, research and optimization. In this work we considered the industrial-scale facility of Western Siberia, which includes a line of methyl tert-butyl ether production in a reactive distillation unit. Aspen HYSYS® was used as an instrument of simulation and further optimization studies. The calculation error of the model does not exceed 5%. Simulation of the feedstock composition changes showed that more preferable hydrocarbon fraction for the process is isobutene-isobutylene fraction. After the optimization study we obtained values of optimal reflux ratio for isobutene-isobutylene fraction to be 0.75 and for butylene-isobutylene fraction - 0.80; optimal methanol flowrate for isobutene-isobutylene fraction is 6.500 ton/h, for butylene-isobutylene fraction -6.000 ton/h.
