Mixture of low
relative volatility is
separated by
extractive
distilation. The 3rd
party solvent
added interact wid
all components of
mixture thus alter
relative volatility
and make
separation easier.
Solvent selection
is important.

Answer / dinesh patil

Some of the Liquid componets (suppose A & B) are difficult
to seperate under normal tempreture & pressure or due to
low boiling point difference (when the mixture is
Azotropic) So requirment of extractive distillation raise.

In extractive distillation solvent component (Suppose C)is
added in such a way that it preferably extract only one of
component among A or B and after ward distillation
operation can be done.

Answer / ravi

Extractive distillation is defined as distillation in the
presence of a miscible, high boiling, relatively
non-volatile component, the solvent, that forms no azeotrope
with the other components in the mixture.

Answer / muthukumar

when feed supplied goes to reboiler section we call it as
extractive distillation and here the third component is known
as solvent

Answer / muthukumar

Extractive distillation is one where the excess feed goes to
Re-boiler section.

Answer / rajesh kumar bhagat

In this we add a entrainer, who alter the relative volatality
of one component(minor component)of azeotropic mixture and we
distilled that component out. and major component with
entrainer will be the bottom product.

4 Answers   Reddy Labs, Reliance,

ENVIRONMENTAL ENGINEERING - QUESTION 22.2 : Biochemical Oxygen Demand (BOD) could be calculated using the formula BOD = (DOi - DOf) (Vb / Vs) where Vb = Volume of bottle in ml, Vs = Volume of sample in ml, DOi = Initial dissolved oxygen in mg / L, DOf = Final dissolved oxygen in mg / L. (a) By using a bottle of Vb = 300 ml with sample Vs = 30 ml, find the BOD if DOi = 8.8 mg / L and DOf = 5.9 mg / L. (b) By using a bottle Vb = 600 mL with sample Vs = 100 mL, find the BOD if DOi = 8.8 mg / L and DOf = 4.2 mg / L. (c) Find the average BOD = [ Answer of (a) + Answer of (b) ] / 2. (d) If the BOD-5 test for (a) - (c) is run on a secondary effluent using a nitrification inhibitor, find the nitrogenous BOD (NBOD) = TBOD - CBOD. Let TBOD = 45 mg / L and CBOD = Answer of (c).

Question 44 - In a non-dilute absorber, graphical method is used to represent the process. In an X - Y coordinate system, X-axis represents mole of carbon dioxide / mole of water and Y axis represents mole of carbon dioxide / mole of nitrogen. The inlet gas stream consists of 8 mol % of carbon dioxide in nitrogen. (a) Find the S / G minimum as a slope that goes through the point (0, 0.0304) and (0.0000488, 0.086957). (b) Find the actual slope of operating line when it is 1.5 times the S / G minimum! (c) Find the value of x for inlet gas stream when y = 1640 x, y is mole fraction of carbon dioxide in nitrogen.
