2020 REFINING PROCESSES HANDBOOK PROCESS CATEGORIES COMPANY INDEX DISTILLATION Divided Wall Column Technology Application: The separation of multicomponent mixtures in more than two fractions of substances by replacing sequentially operated columns with a single column, thus minimizing CAPEX and energy requirements. Description: The thyssenkrupp divided wall column (DWC) technology is an excellent tool for optimizing new plants, revamps, enhancing plant capacity and improving product qualities and yields. Existing columns can be modified within a short shutdown time, resulting in low production losses. Columns in such configurations are fully thermal coupled and provide significant energetic advantages over conventional fractionation technologies. The former proprietor of this technology was ThyssenKrupp Uhde GmbH. Product A Feed Product B Economics: Advantages of DWC in comparison to a two-column system * Up to a 20% reduction in investment costs * Up to a 35% reduction in energy costs * Up to a 40% reduction in required plot area. Installations: Several installations are utilizing thyssenkrupp DWC technology. A wide variety of DWC's are implemented in gasoline and aromatic complexes, such as stabilizer columns, C5 /C6 /C7+ cut fractionators and BTX separation. The latest application of thyssenkrupp DWC technology for a reformate splitter unit is now under construction (2017). Special Developments: The DWC technology was successfully applied within the Morphylane® Aromatic Extractive Distillation technology. The first of its kind single-column Morphylane plant for the recovery of TDI toluene went onstream in 2004. A second single-column Morphylane plant is in the design phase.
