Development of a port-stream based equation oriented modelling of dividing wall column using MOSAIC

Dividing wall column (DWC) is considered as a complex non-standard distillation column. The different sections configurations within the DWC divided by the vertical wall inside the column increase the complexity of modelling DWC due to the existence of recycle loops or interconnecting streams. An eq...
