“…Distillation is one of the essential separation technologies in the chemical industry and provides an effective technique for separating mixtures. , A dividing-wall column (DWC) is a typical distillation column that is fully thermally coupled. , The advantage of a DWC is that three or more composition mixtures could be separated in a single column, which means only one condenser and reboiler are used. , Therefore, a DWC can reduce capital investment and potentially save substantial energy compared with traditional direct distillation (Figure S1a) and indirect distillation (Figure S1b) sequences. − Compared to other thermally coupled distillation schemes, DWC can also avoid back mixing. DWC has been implemented successfully in industry by companies such as BASF and UOP .…”

The unique construction of the dividing-wall column (DWC) has the potential for both energy and capital cost conservation. A sufficiently robust control strategy is needed to handle the DWC because it is a complex multivariable system with high process nonlinearity and time lag. In this paper, the single-factor, response surface methodology (RSM), and particle swarm optimization (PSO) optimizations are applied to the DWC, and the optimal operating parameters are obtained. Then, a sliding mode control (SMC) method is proposed for DWC. Specifically, the DWC is estimated by a first-order pure lag transfer function, and the SMC controller is developed with the aid of the Interpreted MATLAB Fcn of MATLAB/Simulink. Finally, the dynamic responses of both SMC controller and proportional-integral-derivative (PID) controller are analyzed using the disturbance in the feed flow rate (F). The results show that the settling time, oscillation, and steady-state deviation of the SMC controller are less than those of the PID controller. In this way, the SMC could present a better option for control of a complex distillation process, such as the DWC.

“…Various feasible control schemes were proposed, including a composition control scheme, a TC scheme, and a composition/temperature cascade control scheme. Jia et al [17] investigated a new optimization strategy with a support vector machine strategy, as well as a particle swarm optimization method for the synthesis and design of the three-product DWC. They [18] also compared the TC and composition/temperature cascade control structures on the basis of the same system, and the results show that a pure temperature control structure is the best.…”

A dividing wall column (DWC) effectively intensifies the distillation process with a reduced energy consumption, capital investment, and space. The three-product DWC has been investigated intensively and extensively; however, the four-product Kaibel DWC has received scarce attention. This study aimed to propose feasible control structures for the Kaibel DWC using only temperature sensors in order to promote its industrialization. Two temperature control structures, two temperature difference control structures, and two double temperature difference control structures were studied. The feasibility of the six proposed control structures was verified with a wide variety of feed disturbances. In most cases, temperature difference control was better than temperature control to maintain product purities. The dynamic performances proved that the inserted feed disturbances were handled well. These results help to promote the industrialization of the Kaibel DWC.
