Hi nice tutorial, BTW can you share the video how to do reactive Column Distillation for Ethylene Oxide to Ethylene Glycol process? I try but keep error.
Hi. I encountered a problem on my simulation following your steps. The error says "missing interaction parameters for binary pair Methanol/Propylene Carbonate." How can I fix this kind of error? Do I need to try another thermodynamic package?
Hi sir. How to calculate the stream of RD bottom 0.01kmol/s ? In the Journal, the stream of RD bottom is MeoH 472.6kg/h, PC 1.8kg/h, DMC 0.1kg/h, PG 1868.2kg/h.
Hi Sir! I did get this error " The given key was not present in the dictionary" from my first simulation run. Double checking with your file with mine, I did not change the thermodynamic package instead I change the components in the recycle stream to its initial values and rerun. It took me quite some time to run it but i did manage to get the results pretty close to yours (still sad because it's not exactly the same :( huhu) . My mole flow for DMC at stream D1 is 53.49kmol/h. thank you again for the videos and hope that you'll have the time to make more project tutorials using the latest DWSIM version!
hi sir, i got an error with the user model cape-open unit operation, in the error message said "Exception from HRESULT: 0X80040501" do you know how to fix it sir? thank you
In that case just change the property package and run again. I hope it will solve the problem. If not, then I will share a link to everyone to download the file for this simulation.
@@eduXinsight I have followed each and every step that u showed in tutorial also tried different property package still it's not converging. It would be a great help if you can just share the file.
@@eduXinsight can we have a copy of your simulation? I have the same problem. Also tried to change the property package but encountered the same error. Thank you in advance and more power
Hi, I work in the grain whisky industry and I'm looking to build a simulation of the process taking into consideration the granular/particulate physical composition of the feed stock to the distillation column; can I represent this physical composition in DWSIM and how do I do it. Thanks
Thank you so much for your brilliant efforts. Very useful! Excuse me. I get this error for MeOH stream: " The given key was not present in the dictionary". What can I do please?
Hello. Can you please add the simulation report of this. This would be helpful
I upload the simulation file. just check the link in the description of this video. I hope it will be helpful for you.

Yes you have to change the thermodynamic property package. It will eliminate the error

Glad you managed to simulate.
Excellent video!
hi sir, i got an error with the user model cape-open unit operation, in the error message said "Exception from HRESULT: 0X80040501" do you know how to fix it sir? thank you
when I tried to set up the simulation, the parameters for binary pair Methanol/Dimethyl Carbonate are missing, where did you get those parameters?
In that case just change the property package and run again. I hope it will solve the problem. If not, then I will share a link to everyone to download the file for this simulation.
@@eduXinsight same problem here can you provide the link for the binary parameters?

@@paulandrewmadlangbayan2081 I will look it into documents . If I find it I will share it with you

I think you can do that in DWSIM
Sir in cape under properties I don't find any thermodynamic property mentioned only reactions was showing please help me to solve
Same doubt for me too
error calculating excess enthalpy from activity coefficients..how to get away with this
Hello. Is there any chance that you can share the .dwxmz file of this simulation?
I upload the simulation file. just check the link in the description of this video. I hope it will be helpful for you.

@@eduXinsight it didn't work, do you have another alternatives?
How can we do sensitivity analysis of this process I have doubt how can I contact you?
Sir in CAPE the list is not showing on my screen can you please give the reason that why it is happening
Hi Ritu, please update your DWSIM with latest version. I hope It will work.
@@eduXinsight thank you sir😊😊
