Test 1 - Fall 2018 Flashcards
Distillation is possible only if the solution components are
volatile
If the vapor pressure of the two components in a binary mixture is the same, then it is a
azeotrope
The use of vapor produced from the reboiler is
to increase the temp or the fractionator bottom
The reflux of liquid produced from the condenser is
to strip out less volatile component from the vapor
The light key components are
more volatile
the heavy key components are
less volatile
the feed enters the distillation column at its dew point, then the slope of the feed line is
0
If the feed enters the distillation column at its BP, the the slope of the feed line is
infinity
At total relux
disitillate is 0
The point where the operating line and the equilibrium line meets in distillation methods is known as
pinch point
Gilliland Correlation is arranged to estimate the
of stages
Once the components are identified, in a multicomponent distillation they are called
key components
Raising the column pressure, results in
lower relative volatility
