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

PROCESS DESIGN - EXAMPLE 21.2 : The names of the flow streams could be represented by : H1 for first hot stream, H2 for second hot stream, C1 for first cold stream, C2 for second cold stream. Data of supply temperature Ts in degree Celsius : 150 for H1, 170 for H2, 30 for C1, 30 for C2. Data of target temperature Tt in degree Celsius : 50 for H1, 169 for H2, 150 for C1, 40 for C2. Data of heat capacity Cp in kW / degree Celsius : 3 for H1, 360 for H2, 3 for C1, 30 for C2. (a) Find the enthalpy changes, dH for all streams of flow H1, H2, C1 and C2 in the unit of kW. Take note of the formula dH = (Cp) (Tt - Ts). (b) Match the hot streams H1 and H2 with the suitable cold streams C1 and C2 to achieve the maximum energy efficiency.
