Abstract: The distillation column with side reactors (SRC) can overcome the temperature/pressure mismatch in the traditional reactive distillation,the column operates at temperature/pressure favorable for vapor-liquid separation,while the reactors operate at temperatures/pressures favorable for reaction kinetics.According to the smooth operation and automatic control problem of the distillation column with side reactors (SRC),the design,simulation calculation and dynamic control of the SCR process for chlorobenzene production are discussed in the paper.Firstly,the mechanism models,the integrated structure optimal design and process simulation systems are established,respectively.And then multivariable control schemes are designed,the controllability of SRC process based on the optimal steady-state integrated structure is explored.The dynamic response performances of closed-loop system against several disturbances are discussed to verify the effectiveness of control schemes for the SRC process.The simulating results show that the control structure using conventional control strategies can effectively overcome feeding disturbances in a specific range.

Key words: distillation column with side reactors (SRC), mechanism models, multivariable control schemes, simulation system, chlorobenzene production
