though it operates at temperature greater than 400 degree C ?

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
(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

Question 86 - (a) Male with genotype GGmm and phenotype gray wingless mates with female with genotype ggMM and phenotype black winged in fruit flies. G is dominant to g in color. M is dominant to m in wing shape. If the actual distribution of the second generation of the fruit flies was as follow : 890 gray wingless, 900 black winged, 115 gray winged, 95 black wingless, calculate the recombination frequency betwen the two genes and distance in recombination units. Let 1 map unit = 1 % recombination. (b) A DNA molecule has 180 base pairs and 20 % adenine. How many cytosine nucleotides are present in this molecule of DNA?

ENGINEERING MECHANIC - EXAMPLE 15.3 : A biochemical trolley of mass 15 kg is towing a trailer of mass 5 kg along a straight horizontal pathway. The trailer and the trolley are connected by a light inextensible tow-bar. The engine of the trolley exerts a driving force of magnitude 100 N. The trailer and the trolley experience resistances of magnitude 10 N and 30 N respectively. (a) Form 2 equations with unknowns T and a, that represents the equilibrium for the 2 systems of the trolley and trailer. (b) Solve the simultaneous equations from the 2 equations that are obtained in part (a) of this question. T is the tension of the tow-bar and a is the acceleration.

Question 69 - A well delivers 225 US-gallons per minute of water to a chemical plant during normal system operation. (a) Calculate its flowrate in the unit of mega US-gallon per day or MGD. (b) The following formula is written next to the chlorine feed point : (chlorine feed rate, lb / day) = (flowrate, MGD) X (dose, mg / L) x (8.34). If this formula is correct, then what should the chlorine feed rate to be in pounds per day (lb / day) if the desired dose is 2 mg / L. (c) Prove by calculations that the constant 8.34 in the formula next to the chlorine feed point is correct. Let 1 US-gallon = 3.78541 L and 1 mg = 0.0000022046 pound.
