Dividing wall distillation comes of age

    Research output: Contribution to journalArticlepeer-review


    A description of dividing wall columns (DWC), also known as partitioned columns was presented. It was BASF which installed the first dividing wall column in 1985. Now, over 40 such columns are now operational at the company's site worldwide and several others have been installed under their licence. DWCs offer significant advantages over conventional distillation arrangements. The energy required by the reboiler and condenser is significantly reduced, and the use of a single column shell to produce three or sometimes more products reduces capital investment.
