Selective hydrogenation and separation of C3 stream by thermally coupled reactive distillation

Methoxy‐methylheptane as a cleaner fuel additive: An energy‐ and cost‐efficient enhancement for separation and purification units

“…On the basis of a combination of a radial basis function neural network (RBFNN) and genetic algorithms, Ge et al 45 explored a systematic and efficient method for minimizing the total cost of DWC. Qian et al 46 optimized decision variables using a particle swarm algorithm for the design and synthesis of a reactive DWC. Recently, to find the feasible design parameters in a highly nonlinear and multivariable problem, Jia et al 32 studied the optimal design of a DWC using a support vector machine (SVM) and particle swarm optimization.…”

Design and control for a dividing‐wall column with a partial condenser for pretreating an industrial multi‐component reformed gasoline mixture

“…Avoiding the remixing effect leads to higher thermodynamic efficiency and ensures higher purity of the side product stream . Because of the significant benefits on investment costs and energy savings, the DWC has been gradually adopted in industrial applications, e.g., extractive distillation, azeotropic separation, and reactive distillation …”

“…It has been shown that the three‐point temperature control has a better performance than the three‐point concentration control. The three‐point temperature control structure is mostly effective, but in some cases, small changes in the feed flow rate could not be handled if the RL is kept constant . Wang and Wong investigated the effects of the liquid split ratio ( RL ) and the vapour split ratio ( RV ) on the DWC energy efficiency and the controllability for separating ethanol, n ‐propanol, and n ‐butanol through the three‐temperature control scheme.…”

Enzymatic catalyzed reactive dividing wall column: Experiments and model validation

“…New design methods and investigations of system properties influence on the energy saving potential lead to a better understanding of the apparatus . Additionally the cost saving potential for a series of specific reaction systems has been evaluated . However, there are no publications about a RDWC realized in industry.…”

“…14,15 Additionally the cost saving potential for a series of specific reaction systems has been evaluated. [16][17][18][19][20][21] However, there are no publications about a RDWC realized in industry. One of the reasons is that there has been very little experimental data published showing the operability of reactive dividing wall columns and the validation of RDWC model approaches.…”
