Design and Optimization of Retrofitted DWC

Retrofit of Side Stream Coiumns to Dividing Waii Coiumns 261 Side stream column Dividing wall column 

For example, the stmcture of each column can be determined using the well-known Fenske-Underwood-Gilliland (FUG) method (Long and Lee, 2013d) as follows [Equation (9.1)]  

The feed tray location is determined from Equation (9.2) by assuming that the relative feed location is constant as the reflux ratio is changed from the total reflux to a finite value (Wankat, 2012)
