BTW: Adding more stages is not a trivial matter because it changes the size of the tridiaganol matrix. Also, you'll need extra K-Values. K-Values are the...

Hello Mr Doug Morgan, I am also doing the simulation of a crude distillation column with side strippers and pump arounds. I am using steam as a heating source...
Good question. Steam injection does provide a driving force to get more material in the vapor phase. It's like adding more water to a saturated salt...

Hi Doug!!!!!!!! If steam injection is there in the distillation column.... As we know that y=Kx and y is the mole fraction in the vapor phase. Steam injection...
The K-value in vapor-liquid equilibrium is an equilibrium thermodynamic property. It is defined as the activity coefficient of the species in the liquid...
