The ammonia is burned to form nitric oxide in the next reaction 4NH3+5O2--> 4NO+6H2O If the ammonia is fed to a continuous reactor at a rate of 100 kmol NH3/h along with 40% excess O2 What amount of O2 is fed in kmol O2/h

Acetylene (C2H2) may be formed from methane (CH4) by pyrolyzing-decomposing at high temperature according to the reaction: 2CH4 (g) → C2H2 (g) + 3H2 (g) In a commercial reactor system, the methane is supplied as a liquid at 25°C to a heater where it is heated and vapourised leaving as a vapour at 650°C. The vapour then passes to the catalytic reactor in which a conversion of 40% is achieved. It may be assumed that there are no other reactions, that operation is at a pressure of one atmosphere and that the stream leaving the reactor is all in the vapour state. With a complete block diagram of the process, determine the heat transfer rate (kW) required to the reactor if it is operated isothermally. Evaluate on the value of the heat transfer rate obtained from your calculation.

Consider the pair of reactions in which ethylene is oxidized either to ethylene oxide (desired) or to carbon dioxide (undesired) in the furnace: C₂H4+0₂-C₂H4O C₂H₂ +30₂-2 CO₂ + 2H₂O The feed mixture and air are fed at a temperature To. All gaseous effluents are at temperature T emerging from the non-isothermal reactor. a) Calculate the number of degrees of freedom of the process. How would the answer differ if the reactor were adiabatic? b) Outline a manual calculation procedure to determine the compositions of all streams.
