This paper presents the assessment of the dynamic behavior and the control system response of the isobutane-butene alkylation process, via dynamic simulations performed in Aspen Dynamics. The steps for developing the dynamic models, the control structures and the controllers tuning are discussed. The transient behavior of the plant when different disturbances are considered is evaluated. Two flowsheets are investigated – one with three separation columns and the other one with two separation columns for product purification. The results are presented in graphical form and a comparison between the two flowsheets is performed. Methods for varying the plant throughput and for controlling the product purity are provided.
