Vapor recompression column is a type of energy integrated distillation columns that has a good
potential for applying in industrial plants. In this paper the dynamic simulation and control of a
vapor recompression column by using Aspen-Hysys 2009 was investigated. For this purpose a
control structure with five control loops; two levels, one pressure and two compositions; was
selected. The results of dynamic simulation showed that low interaction exists between the
composition control loops and the selected control structure can work properly in case of changing
in composition set-points and feed disturbances. In addition, the results showed that the energy
saving by using this method would be about 75.8% in comparison with conventional column.
