The optimum conditions was determined by using Aspen plus simulation analysis for the use of benzene / toluene / ortho-xylene system of direct and indirect separation sequence separation. By comparison of fixed costs and energy costs of the two programs, we find that the former fixed costs are 7.61% smaller than the latter, and energy savings of 9%, the total annual cost savings of 8.87%. Finally, by using slope criterion, a heated plate temperature gain criterion and constant temperautre criterion,respectively, we have determined the sensitivity of the rectification column board position and established control structures distillation system, obtaining through dynamic simulation system faces the feed flow rate and feed composition disturbance flow control different sensitivities board transition reboiler heat load, temperature and product purity plates curve analysis, arriving at the optimum temperature control board position.
