For the above liquid vapor equilibrium graph for the ethanol-1 pentanol binary system, we have a 100 kg mol feed mixture that enters the column with 44% molar ethanol and is a liquid at its bubble point. It is required that the distillate contain 96% mole of ethanol and the residues only 2% mole of it. A reflux to distillate ratio of 0.6 kg mol is recommended.

To draw the operating line of the rectifying section Calculate its intercept:

F=Answer

XF=Answer
XD=Answer
XB=Answer

Remember that:

then , D=Response
kg mol (two decimal places).

Reflux ratio to distillate: RD=Response

By global balance of materials F= D + B, then, B=Response
kg mol (two decimal places)

Remember Intercept = .= Answer
(two places)

With these data you build the line of operation of the rectifying section.

For the feed line q is equal to 1.0, for liquid at its bubble point (remember that q=1-f, where f is the fraction of feedr that enters as vapor, in this case 0)

Supply line slope = q/(q-1)= Response

With that slope and starting from the line of 45, at the point of X=XF, draw the power line.

Starting from XB, draw a line that reaches the point where the power line intersects the operating line of the rectification region. Draw the saucers and answer:

# cymbals = Answer
including the kettle

The plate of food is the number Answer

From the number of plates we can infer that this case Answer

to a flash distillation.
