A process stream carrying N_2 and C_2H_2 gases at 25 degree C and each at 10 mol

Question

A process stream carrying N_2 and C_2H_2 gases at 25 degree C and each at 10 mol/s is preheated to 500 degree C by a heat exchanger before entering a reactor where the only reaction occurring is N_2(g) + C_2H_2 (g) rightarrow 2HCN(g). (a) Calculate the heating requirement provided by the heat exchanger. (b) Calculate the heat of reaction at 500 degree C for the reaction. (c) Based on your (b), should heat be added or removed and in what amount if the reactor is operated isothermally at 500 degree C? (d) What will happen to the reactor temperature if the reactor is operated adiabatically? Briefly explain justify your answer.

Explanation / Answer

A. The reaction should be carried out in low pressure flow reactor using a leak to mass spectrometer

B. dH --- n.Cp.dT calculate by using this formula.

C.The reaction is accelerated by increasing temperature and pressure.

D. In adiabatic process the value of q is zero.The reaction should not be continuously heated and pressure should be low.
