Suethanol saturated solution, of which 58% by weight is ethanol (C2H5OH) and 45% condensed as a result of heating and cooling, is fed to the distillation column at a molar rate of 250 kmol/h. The bottom product composition is 5% mole of ethanol, while 20% by mole of the stream exiting the full concentrator integrated with the column is water. It is given that the backflow rate used throughout the process is RD=1.4RD,min. Ptotal= 1 atm. and T= 298 K, the liquid-vapor equilibrium curve data of the ethanol-water mixture are given.
