Question
Consider a feed stream consisting of three components and flowing at 1 mol/min as in the following
figure. The stream is separated into two streams D and R.
1 mol/min
XIA (mol A/mol)
X1B (mol B/mol)
X1c (mol C/mol)
STILL
D (mol/min)
YA (mol A/mol)
YB (mol B/mol)
Yc (mol C/mol)
R (mol/min)
XA (mol A/mol)
XB (mol B/mol)
Xc (mol C/mol)
XfA=0.3
with XB = 0.311
Xfc=0.389
Suppose it is known that D = 0.393 mol/min, y₁= 0.323, and y³ = 0.363. What are the values of the
remaining process variables? Have a degree of freedom analysis first on the ternary still.
