denote mole fractions of the more volatile component, while B, D, R, and F represent molar flow rates.
It is desired to control distillate composition y despite disturbances in feed flow rate F. All flow rates
can be measured and manipulated with the exception of F, which can only be measured. A
composition analyzer provides measurements of y.
