Answer / ibrahim khan

To catch fire, fire triangle's condition, i.e. Fuel, Ignition source, and Oxygen must come in contact. Hence it doesn't catch the fire.

Answer / rajesh kumar bhagat

Because, to catch fire oxygen is necessary and column works
with no presence of oxygen and air.

Answer / prashant chalke

fractionating columns at these high temperature are mostly
operated at low pressure or in vacuum hence there is no
chances of taking fire.

Answer / वै&#23

(This answer is purely based on my thermodynamics knowledge i gained till now)
Fire can only be produced in case of a combustion reaction.
And it can take place only if their is any free radical or unstable compound which can react with oxygen. It does not depend on temperature at all. So as fractionating column contains a mixture of two stable compouds, their is no chance of catching fire in the column, what so ever be the temperature.

Answer / rajeshkannan

in order to catch fire for any material it must reach its
auto ignition temperature

ACCOUNTING AND FINANCIAL ENGINEERING - EXAMPLE 34.10 : Let D be the random outcome of rolling a dice once. A new dice has values of D* = D - 3.5. There is a total of n rolls of a dice. (a) Find the variance for D* by using the formula 6 V = [ D* (D = 1) ] [ D* (D = 1) ] + [ D* (D = 2) ] [ D* (D = 2) ] + [ D* (D = 3) ] [ D* (D = 3) ] + [ D* (D = 4) ] [ D* (D = 4) ] + [ D* (D = 5) ] [ D* (D = 5) ] + [ D* (D = 6) ] [ D* (D = 6) ]. (b) Calculate the standard deviation of D* as a square root of V. (c) Another new dice has values of D** = kD*. (i) Find the value of k so that D** has a standard deviation of 1. (ii) Find the values of D** for each outcome of D = 1, 2, 3, 4, 5 and 6, when the standard deviation is 1. (iii) Given that the average score of a dice is 3.5, find the equivalent, new and improved model of a dice, Sn in term of n and D**. (iv) Find the expected value of D** as the average of D**.
