|
I have already opened DWSIM on my machine.
|
Type Nitrogen in the Search tab
|
First, we will add the compounds.
|
Point to Property Packages
|
Now comes Property Packages.
|
Point to Flash Algorithm
|
We are moved to Flash Algorithm.
|
Point to System of Units
|
Next option is System of Units.
|
Let us maximize the simulation window. | |
Point to Object Palette
Click and drag Material Stream to the flowsheet |
Now let’s insert a feed stream that enters the PFR.
|
Click on MSTR-000 | Click on Material Stream “MSTR-000” to view its properties. |
Type Feed | Let’s change the name of this stream to Feed. |
Input Data>> Flash Spec>> Temperature and Pressure(TP) | Now we will specify the Feed stream properties.
|
Input Data >> Temperature >> 425 C
Press Enter |
Change Temperature to 425 degC and press Enter to accept the new value. |
Input Data >> Pressure >> 200 bar
Press Enter |
Change Pressure to 200 bar and press Enter. |
Input Data >> Mass Flow >> 3600 kg/h
Press Enter |
Change Mass Flow to 3600 kg/h and press Enter. |
Now let us specify the feed stream compositions. | |
Composition >> Basis >> Mole Fractions | Under Composition, choose the Basis as Mole Fractions, if not already selected.
|
Nitrogen: 0.5
|
Now for Nitrogen, enter the Amount as 0.5 and press Enter.
|
Click Accept Changes | On the right, click on this green tick to Accept Changes. |
Now we will define the Kinetic Reaction. | |
Tools >> Reactions Manager
|
Under Tools, click on Reactions Manager.
|
Chemical Reactions >> Add Reaction | Under Chemical Reactions tab, click on the green coloured Add Reaction button. |
Click on Kinetic | Then click on Kinetic. |
Point to Add New Kinetic Reactions | Add New Kinetic Reactions window opens. |
Identification >> Name >> Ammonia Synthesis | First part is Identification.
|
Description >> Irreversible reaction for synthesis of Ammonia from Nitrogen and Hydrogen | Next, enter the Description.
|
Point to Components, Stoichiometry and Reaction Orders | Next part is a table of Components, Stoichiometry and Reaction Orders. |
Point to Name field | First column Name, shows the available components here. |
Point to Molar Weight | Second column corresponds to its Molar Weight. |
Point to Include | Next column is Include.
|
Point to BC
|
Fourth column is BC.
|
Point to Stoich. Coeff
|
Next column is Stoich. Coeff. (stoichiometric coefficients)
-3 for Hydrogen, and for Ammonia 2 Then press Enter.
|
Point to Stoichiometry field | In the Stoichiometry field, we can see it is showing OK.
|
Point to Equation field | Here the Equation field shows the reaction equation. |
Point to DO
|
Next column is DO, which indicates direct/forward reaction order.
|
Point to RO | Next column is RO which indicates reverse reaction order.
|
Point to Kinetic Reactions Parameters | Then comes Kinetic Reactions Parameters. |
Basis >> Molar Concentrations | Our rate is in terms of molar concentration.
|
Fase >> Vapor | Select Fase as Vapor. |
Point to Tmin and Tmax
|
Next is Tmin and Tmax.
|
Tmin (K) >> 700
|
So, enter Tmin (K) as 500 and Tmax (K) as 2000. |
Point to Direct and Reverse Reactions Velocity Constant
|
Now go to Direct and Reverse Reactions Velocity Constant.
|
Click OK
|
Click OK and close the Chemical Reactions Manager window. |
Go to Object Palette>>Unit Operations
|
Now let us insert a Plug-Flow Reactor (PFR) into the flowsheet.
|
Click and drag Material Stream to the flowsheet | We will insert one Output Stream.
|
Type Product | We will change the name of this stream to Product. |
Click and drag Energy Stream to the flowsheet | Next, we will insert one Energy Stream. |
Type Energy. | And name this stream as Energy. |
Click Plug-Flow Reactor (PFR) | We are now ready to specify the Plug-Flow Reactor.
|
