Distillation : McCabe-Thiele

Distillation : McCabe-Thiele Method

Description:

Calculates distillation parameters per the McCabe-Thiele method as indicated in the reference below. User must input a relative volatility for the most volatile component. The equilibrium curve is generated per this value. The relative volatility is assumed to be constant throughout all concentrations (mole fractions).



Alternative Descriptors:


Binary Distillation Modeling, McCabe Thiele distillation modeling.

Calc Number:


DS-MCCSMI-0031

Calc Status:


Beta

Reference:


Unit Operations of Chemical Engineering, Third Edition, McCabe and Smith, pgs. 551-563

Reference Example(s) Modeled/Generalized:



Calc Origination Date:


04/04/2006

Calc Originator:


RBC

Calc Revision History:


Calc Guidelines:


See the above reference
