Reactive Distillation Process Analysis in a Divided Wall Column
نویسندگان
چکیده
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 flow CSTR series. Proposed solution is attractive from industrial point of view. As case study isoamylenes (contained in fluid catalytic cracking-FCC-C5-fraction) etherification with ethanol (EtOH), to obtain tert-AmylEthylEther (TAEE) in RDWC with structured packing was illustrated. Operation of such arrangement involves very careful solution of the model. Composition profiles demonstrated feasibility of proposed flowsheet.

In the present work, the optimization of different structural and process parameters of a divided wall column (DWC) for the energy efficiency has been presented. The optimal design and operation of divided wall distillation columns involve a number of variables and is a non-linear problem. Rigorous simulation of a DWC was carried out using Multifrac model of ASPEN Plus software. Box–Behnken des...
