摘要

Abstract

The “neat” operation of the two-reactant reactive distillation column has better steady-state economics

while it presents a challenge for design

optimization

and control of the process. Based on the optimal economic design

the dual-composition control structure and dual-temperature control structure are designed respectively for the benzene chlorine consecutive reactive distillation process. The effectiveness and robustness are analyzed comparably for the disturbance resistance in terms of changes of production rate and feed composition. Results show that dual-temperature control with propose selection of tray temperatures and the optimal profile of the set point can provide better transient process performance than the composition control structure.
