Hi$,$ please answer to the list of questions below using information provided in the images. Please provide the Aspyn file or a step by step proedure with screenshots or guidelines for completing this question. Thank You.

Classify the above reactions as reversible or irreversible.

What are the units of reaction rates?

What does the first term in r$2$ represent? What does the second term represent?

What component property is used as the basis in the above rate expressions? What is its unit?

What is the order of reaction $(1)$ with respect to Toluene? Hydrogen? Remember that the order

of a reaction is NOT the same as the stoichiometric coefficient.

Which parts of r$1$ and r$2$ are Arrhenius rate constants $($k and k $)?$

What are the pre$-$exponential factors for the two reactions?

What are the activation energies for the two reactions?

Use Peng Robinson. Add reactions $(1)$ and $(2)$ in Hysys using the kinetic model as RM$.$ Use the

correct units and note that E is positive. Specify the right phase for each reaction.

The reactor has the following design and operating data:

$1.$ Feed temperature is $1150\backslash$deg F in order to achieve good reaction rates.

$2.$ Feed pressure is $500$ psia. $($Can pressure increase across the reactor?$)$

$3.$ Product temperature should not exceed $1310\backslash$deg F to avoid coking.

$4.$ The molar flow of hydrogen feed is at least five times that of the toluene fee. $($Why

should you use a higher ratio? What are its effects?$)$

$5.$ The reactor uses $250$ tubes with $4\mathrm{.}53$ cm internal diameter and $2\mathrm{.}8$ mm wall thickness.

Specify $4\mathrm{.}53$ cm as tube diameter in Hysys$.$

$6.$ The void fraction of catalyst is $0\mathrm{.}4.$ Assume the Hysys$-$default data for the catalyst.

As the first step, make reactor adiabatic and specify pressure drop as zero. Use Adjust to find the tube length $($L$)$ to achieve $70\%$ conversion of toluene via the primary reaction. Please strictly

follow the procedure in the notes for using Adjust. $($~ $4\mathrm{.}5$ m$)$

What is the product temperature? $($~ $1303$ F$)$

Keep the reactor adiabatic, but remove the user$-$specified pressure drop of zero and use Ergun equation for all subsequent parts.

What is the pressure drop on the tube side? $($~ $161\mathrm{.}1$ kPa$)$

For the above pressure drop, what tube length will give $70\%$ conversion? $($~ $4\mathrm{.}66$ m$)$

What is the product temperature? $($~ $1303$ F$)$

Explain why the pressure drop affects the required tube length.

Remove Adjust and set L $=4\mathrm{.}5$ m$.$ Study and describe the effect of feed temperature on the reactor conversion
