However, the respective vapor splits have to be properly designed and require consistent hydrodynamics in the adjacent column sections. These limitations can be overcome by transformation of the thermal coupling to a side stream configuration, which adds a degree of freedom for operation of the process and allows the columns to be operated at different pressures. The current study investigates energy requirements and operating costs of single side stream configurations thermodynamically equivalent to side-rectifier and side-stripper columns in comparison to fully thermally coupled dividing wall columns and heat-integrated configurations. While side-stream configurations provide an interesting retrofit option and are competitive to fully-coupled dividing wall columns for certain ranges of feed compositions, they can outperform them significantly exploiting additional heat integration.enhttp://rightsstatements.org/vocab/InC/1.0/Dividing Wall ColumnThermal CouplingLiquid Only TransferHeat IntegrationShortcut ModelingTechnikIngenieurwissenschaftenConference Paper10.15480/882.488210.15480/882.4882Conference Paper
