BACKGROUND: Distillation is a separation process with a high energy consumption. Therefore, energy-saving optimizations of the distillation process have become particularly significant. However, developing methods to quickly choose the best energysaving distillation sequence for the separation of multiple components has become a key problem. RESULTS: In this paper, the Distillation Sequence Morphometry Analysis Method (DSMAM) was established to quickly screen energy-saving and efficient distillation sequences and was integrated with a Dividing-wall column (DWC) device, which has more industrial significance. Meanwhile, an evaluation and screening index η of separated multicomponent energy-saving distillation sequences was proposed. Finally, based on the DSMAM, and combined with Microsoft Visual Basic 6.0 (VB) and Aspen Plus V11 (Aspen) software, a set of distillation sequence screening and evaluation programs of four-component separation systems was generated. The distillation column sequence with high thermodynamic efficiency and the energy-saving coupling structure of distillation were obtained quickly and accurately. CONCLUSION: This program was applied to the separation of the n-butane-benzene-n-heptane-n-nonane system. It was able to quickly obtain the first three energy-saving distillation sequences without thermal coupling and the first three energy-saving distillation sequences in the search space. The direct-thermal coupling distillation sequence of the energy-saving fluid was integrated and coupled, providing a preliminary design reference for industrial design and application.

“…Aspen software was used to model the packed tower, absorption heat pump, and steam subsystem. As shown in Figure 6A, the RadFrac model 24 was used to simulate the process in a packed tower, the components include N 2 , O 2 , CO 2 , H 2 O (l) , and H 2 O (g) , the streams include GAS‐IN, WATER‐IN, GAS‐OUT, and WATER‐OUT. The theoretical plates number is 3.5 of HX‐350 structured packing with unit thickness, and the total height of structured packing used in this system is 1.20 m, the number of stages was set to 4 in simulation without condenser and reboiler.…”

Summary For coal‐fired hot water boilers, we developed a comprehensive waste heat recovery system coupled with a packed tower, industrial steam turbine, and absorption heat pump, which can directly reduce the auxiliary power consumption, realize energy cascade utilization, and waste heat recovery. The ASPEN Plus software was used to simulate the packed tower, absorption heat pump, and industrial steam turbine system. The design parameters of the system were obtained and the operation characteristics of the system under load rates of 25%, 50%, 75%, and 100% were investigated, the feasibility of steam subsystem transformation was also analyzed. Taking a 140 MW coal‐fired boiler as an example, in the range of 25%~100% load rate, the direct energy saving can reach 118 to 523 kW∙h, the waste heat recovery power is 2.7 to 11.4 MW, and the coal saving can reach 374 to 1605 kg/h, resulting in energy and resource consumption reduction effect, the system also has CO2 and pollutant emission reduction effect. The RadFrac model can be used in packed tower design, the system can work well under variable load conditions.

As the culmination of the Chemical Engineering curriculum, students face the challenging and stimulating elaboration of a whole design project that integrates all the knowledge gained throughout the course. The subject is divided into two parts, gaining a theoretical background in the ninth semester and a proposed teamwork project design with the aid of a process simulator in the tenth semester. This paper presents the challenge of designing a whiskey distillery elected by a group of students applying the project‐based learning methodology. As a strategy for a more efficient design, the process is divided into three blocks: prefermentation, fermentation, and distillation. Calculations involve mass and energy balances and the design of the different units, including the optimization of a distillation column assisted by the ASPEN HYSYS® simulator. Students must publicly present their results in front of the class and a jury formed by chemical engineers. A survey was carried out to assess the student's satisfaction and feedback. The results manifested the significance of the subject for the future and the satisfaction of the proposed teaching strategy.
