![]() Hence extractive distillation is clearly the more economical process. can obtain limited parameters (such as molecular weight and boiling point) from the. ![]() (PAH) compound with the structural formula shown in Figure 2.9. ![]() Extractive distillation was determined to be costing less than13⁄ times the price of conventional distillation process. Introducing Aspen Plus V11 for Chemical Engineering Simulation. A fraction of hydrocarbons with a known range of normal boiling point can be represented. Cost efficiency was used as the criteria to determine the best process. Cost analysis was performed by using aspen cost analyzer. Comparison of the energy consumed by both the processes to achieve the same separation efficiency was done. Aspen Hysys was used as the simulator of choice for simulating both conventional distillation and extractive distillation, whereas Aspen Plus was used to compute the VLE data for interaction of the three compounds with each other. A literature review has been performed for both conventional and extractive distillation and also the advancements and new techniques developed to increase the efficiency of both processes. In the present paper, an intensive analysis of simulation of conventional distillation and extractive distillation to separate a mixture of toluene and heptane (toluene-heptane azeotrope) has been performed. ![]()
