Dividing wall column (DWC) is an advanced technology which could decrease energy consumption. As the vertical inserted in DWC increases degree of freedom systems, control becomes more difficult than conventional columns. In this study, mixture glycols (1, 2-propanediol+ 1, 3-butanediol+ 4-butanediol) were taken as feed, optimized structure was proposed, and three structures for tested by ± 10% ...

The reactive-extractive distillation (RED) has the advantages of combining beneficial features both reaction and separation processes. Relative to conventional reactive or extractive distillation-based processes, RED is also less energy intensive as it relies on heat produced for subsequent process. Therefore, application ternary azeotropic become subject popular interest, evident by increasing...

Abstract Dividing-wall columns(DWC) are intensified distillation systems for multicomponent separations. They have the potential to save both energy and capital costs significantly than conventional simple column configurations. The several DWC columns for ternary distillations have been figured out by some creative activities from different inventors. Recently they have gained the momentum to ...

Natural gas usually contains significant amounts of acid gases when it is extracted from underground reservoirs. Therefore, it must be treated by appropriate processes to remove these acidic components. In this study, the simultaneous absorption of carbon dioxide and hydrogen sulfide from natural gas into diethanol amine solution was simulated using CFD. Absorption process was performed in a we...

This contribution aims to present a methodology to model and simulate the reactive dividing wall column (RDWC) using commercial software. Feasibility of separation scheme was established with ASPEN DISTILTM. Simulation of flowsheet configuration was performed with ASPEN HYSYSTM, using the two columns model. The reactive zone hosted by the prefractionator was modelled and simulated as backward f...

Abstract The development trend of Fischer–Tropsch (F–T) technology is to develop high value-added products. separation linear α -olefins with low cost an effective method. Nevertheless, the lack thermodynamic data and huge energy consumption are two main problems restricting process. key components (1-dodecene n -dodecane) in F–T product were measured. Wilson binary interaction parameters obtai...
