The combustion of n c3h8 = 100 kmol.h-1 propane gas ( pure fuel stream) takes place at isobaric-atmospheric conditions ( P= 1atm) in a continuous reactor, in the presence of air and using an oxygen inlet of n O2­( g) = 1000kmol.h-1 according to:

C3H8 + 5O2( g) ----- 3CO2 + 4H2O

The inlet gases are supplied at T=25oC, and leave the reactor at T= 300oC, according to the following values:

balance
  1. Calculate the extent of reaction and fractional conversion of propane
  2. Calculate the High Heating Value HHVC3H8 and specific heat of reaction R1 at 25oc and 1atm
  3. Calculate heat released or absorbed in the process ( MW)

If the reaction takes place in a tubular reactor, following a first order kinetics, according to

-rC3H8 ( g) = K. Cc3H8( g)    k = 60hr-1

Iv estimate the reactor volume needed to carry out the reaction in previous conditions, c3H8 (g) = 0.5
