REACTOR
Reaction:
A B+C
(D is inert)
Component-A is converted to component-B and component-C in the presence of inert-D in a fixed
bed reactor by the reaction above.
a) If Fi, XIA, XIB, Xịc, XịD, Ti, Pi are the variables at each stream (i) and r (conversion) APR, Qr are
the unit parameters of the reactor, calculate degrees of freedom (DOF) for the reactor.
b) Calculate the composition of the product stream if the flow rate of the feed stream is 120
kmol/h in which the molar fractions of A, D and the conversion of A in reactor are 0.70, 0.30
and, 0.80 respectively.
c) Consider the data in the table and calculate the temperature of the outlet stream of the
reactor (T2) if the temperature and the pressure of the feed stream is 625 °C and 1 atm,
respectively, if the reactor is working at adiabatic and isobaric conditions (QR=0, APR=0).
Hint: Use a numerical method on Excel platform (you should upload the excel file)
