Dividing wall columns (DWCs) are an attractive option when the goals are to reduce energy consumption and capital investment for distillation processes. A major component in a DWC system is the reflux splitter, which separates the liquid products from the column overhead into two liquid streams: one to the prefractionation section and the other to the main column section of the DWC. A more reliable reflux-splitting system stabilizes the entire column, thus minimizing unit/process downtime. Several novel developments for a reflux-splitting system can improve the operation and reliability of DWCs. Background DWC technology has been successfully applied in various petrochemical processes.1,2
