You desire to flash 20 moles/min of a liquid mixture
containing 20% by mole chloroform (1) and 80% by
mole ethanol (2) at 332.4 K in a flash distillation unit
operating at 70 kPa. You do not know a lot about this
mixture at this temperature, other than the fact it exhibits
an azeotrope (x1 = y1 = 0.84 at 101.3 kPa; Chen,
1995). Since this system forms an azeotrope, you know
not to treat it as an ideal solution. Model the system
using the 1-parameter Margules equation and estimate
whether the mixture flashes at 332.4 K and 70 kPa. If it
does flash, calculate the resulting flowrate and composition
of the stream(s) leaving the flash distillation unit.
