I'm simulating Maleic Anhydride production in hysys
I'm using PRSV fluid package 
and I've defined 3 kinetic reactions in reaction set. main reaction and 2 side reactions.
I used plug flow reactor .

It converged but there is no conversion.
I tried increasing feed temperature also but it didst work
No maleic anhydride is being produced
Can you help me solve it?
Thanks in advance

Hi,

Let you try google & youtube

 :Maleic anydride hysis , you will get some info .

 

Hope this helps

I didn't find anything related to it on google

Hi Fiha ,

I found Youtube quite supportive :

 

Hope it will help you and others.

Fiha,

 

Please let us have your simulation file and a scan of your information about kinetics of reaction.

Fiha,

good. But send your hysys simulation file to check what wrong is it leading to no conversion. Ok?

i'll be really thankful if u can reply soon

Fiha,

I want your hysys file to check your simulation.

Where is it? Please attach the file.

I cant upload it
I dont know y
can i have ur email?
i can email it to u

You should play continuously with number of tubes (I think you should increase a lot), length and diameter of the tubes. Moreover, you should define heat transfer material and its property. For every changing, look at outlet stream until you get maleic anhydride.

hi; you can't upload .hsc file Fiha, save it as .XML and then you can upload it.

best regards

Hi Fiha,

 

Did you solve your problem with no conversion?

If you already need help, please let me know.

I have simulated your process and reached the Maleic anhydride at the outlet of the PFR.
