Question: solve the problem using aspen plus and show ( screenshots ) each steps of your aspen code: P 1 1 - 6 The irreversible endothermic
solve the problem using aspen plus and show screenshots each steps of your aspen code:
P The irreversible endothermic vaporphase reaction follows an elementary rate law
and is carried out adiabatically in a Species A is fed to the reactor at a rate of
and a pressure of atm. An inert stream is also fed to the reactor at atm, as shown in Figure P
The entrance temperature of both streams is
F
Additional information:
exp
degrees Kelvin
a First derive an expression for as a function of and
b Sketch the conversion and temperature profiles for the case when no inerts are present. Using a
dashed line, sketch the profiles when a moderate amount of inerts are added. Using a dotted line,
sketch the profiles when a large amount of inerts are added. Qualitative sketches are fine. Describe
the similarities and differences between the curves.
c Sketch or plot and then analyze the exit conversion as a function of Is there a ratio of the
entering molar flow rates of inerts I to A ie at which the conversion is at a
maximum? Explain why there is or is not" a maximum.
d What would change in parts b and c if reactions were exothermic and reversible with
and at
e Sketch or plot for parts c and d and describe what you find.
f Plot the heat that must be removed along the reactor vs to maintain isothermal operation
for pure A fed and an exothermic reaction. Part f is C level of difficulty, ie P
