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.

NATURAL GAS ENGINEERING - QUESTION 26.3 : The United States of America Energy Information Administration reports the following emissions in million metric tons of carbon dioxide in the world for year 2012 : Natural gas : 6799, petroleum : 11695, coal : 13787. Coal-fired electric power generation emits around 2000 pounds of carbon dioxide for every megawatt hour generated, which is almost double the carbon dioxide released by a natural gas-fired electric plant per megawatt hour generated. If 1 metric ton = 1000 kg and 1 pound = 0.4536 kg, estimate the total energy generated by natural gas in the world for year 2012, in gigawatt hour.

POLYMER ENGINEERING - QUESTION 24.3 : The molecular weights M in kg / mol of 3 different monomers a, b and c in a polymer are Ma = 14, Mb = 16 and Mc = 18, with their respective quantities in N units having the ratio of Na : Nb : Nc = 2 : 3 : 5. (a) Find the numerical average molecular weight of the polymer by using the formula (Ma Na + Mb Nb + Mc Nc) / (Na + Nb + Nc). (b) Find the weighted average molecular weight of the polymer by using the formula (Ma Na Ma + Mb Nb Mb + Mc Nc Mc) / (Ma Na + Mb Nb + Mc Nc). (c) Calculate the polydispersity Q by using the answer in (b) divided by answer in (a). (d) Find the volumetric average molecular weight of the polymer by using the formula (Ma Na Ma Ma + Mb Nb Mb Mb + Mc Nc Mc Mc) / (Ma Na Ma + Mb Nb Mb + Mc Nc Mc). (e) Estimate the polydispersity Q by using the answer in (d) divided by answer in (b).

ACCOUNTING AND FINANCIAL ENGINEERING - EXAMPLE 34.3 : (a) In the M / M / 1 queue that happens with randomness, let State 0 = the queue and server are empty, State 1 = the server is in use and the queue is empty, State 2 = the server is in use and 1 is in the queue, State 3 = the server is in use and 2 in the queue. Let P (0) = probability of State 0, P (1) = probability of State 1, P (2) = probability of State 2, P (3) = probability of State 3 and so on. If c = constant, P (1) = c P (0), P (2) = c [ c P (0) ], P (3) = c { c [ c P (0) ] }, write an equation that involves P (N), P (N + 1) and c. (b) Let L = market price of risk, r = riskless rate, m = expected return, s = volatility. Given that L = (m - r) / s related to oil prices, expected return = 12 %, s = 20 %, riskless rate = 8 %, calculate the market price of risk.
