Translation
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.
Para los siguientes datos, Calcule: Razn de reflujo a destilado: RD= Por balance global de materiales F=D+B, entonces, B= kgmol(doslugares)decimales) Recuerda Intercepto =RD+1xD= (dos lugares) Con. estos datos construyes la lnea de operacin de la seccin rectificadora. Para la linea de la alimentacin q es igual a 1.0, para liquido en su punto de burbuja (recuerde que q=1f, donde f es la fraccin de feedr que entra en forma de vapor, en este caso 0) Para la grfica anterior de equilibrio liquido vapor para el sistema binario Pendiente linea de alimentacin = q/(q1)= etanol-1 pentanol tenemos una mezcla de 100kg mol de alimentacin que entra a la columna con un 44% molar de etanol y es un lquido en su Con esa pendiente y partiendo de la lin ea de 45 , en el punto de X=XF punto de burbuja. Se requiere que el destilado contenga un 96% molar trace la linea de alimentacin. de etanol y los residuos slo un 2% molar de ste. Se recomienda una Partiendo de XB trace un a linea que llegue hasta el punto donde la linea razn de reflujo a destilado de 0.6kg mol. de alimentacin corta a la linea de operacin de la regin de rectificacin. Para dibujar la linea de operacin de la seccin rectificadora Calcule el Dibuje los platillos Y conteste: intercepto de la misma: \# platillos = incluyendo el herbidor F= El platillo de la alimentacin es el nmero XF=XD=XB= Por el numero de platillos podemos inferir que este caso Recuerda que: FD=xDxBxFxB entonces, D= kgmol(doslugaresdecimales)Step by Step Solution
