Abstract

In our previous work

the reactive dividing wall column (RDWC) was proposed and proved to be effective for selective hydrogenation and separation of C3 stream. In the present paper

the dynamics and control of the proposed RDWC are investigated. Four control structures including composition and temperature controls are proposed. The feed forward controllers are employed in the four control strategies to shorten the dynamic response time

reduce the maximum deviations and offer an immediate adjustment. The control structures are compared by applying them into the RDWC system with 20% disturbances in both the feed flow rate and the feed compositions

and the results are discussed.
