Question
Transcribed Image Text:1. Consider a feed stream consisting of the three components and flowing at 1 mol/min as
in the following figure. The stream is separated into two streams D and R. Suppose it is
known that xfA= 0.3, xfB= 0.45, xfC+ 0.25, and xC=0.35, yA= 0.35, and yB=0.55. What
are the values of the remaining process variables? Do the degree of freedom analysis
on the ternary still.
