wonderful, thank you so much

@Chemiopedia 2 года назад

Glad you liked it!

Thank you, this is exactly what I was looking for. Is there any chance you can help me out with the following: I am trying to get the exponents of each reaction for the driving force, When I use the format in Aspen with the A/B parameters and adsorption constants and exponents, if i enter 0, 1, or stoichiometry at the driving force exponents I get errors everytime that indicate my kinetics are faulty.

very helpful. Thank you. Where do you add the values A and B in aspen?

@Chemiopedia 2 года назад

These values of SMR is not added in Aspen in any video.

how to enter kinetic data if the model is mentioned in both partial pressure and concentration in the paper

@Chemiopedia Год назад

can you share further information at support@chemiopedia.com

@redagalih 11 месяцев назад

Very helpful. Please recheck that the k1 in that unit should be 1.17e+12 not 1.17e+15

@Chemiopedia 11 месяцев назад

Both values are correct based on unit of reaction rate. If you are considering rate in kmol/(kgcat s) then 1.17e+12 is correct value. To have unit mol instead of kmol, 1.17e+15 will be used.

Very helpful tool thank you. I have a problem with co2 methanation kinetics in Aspen any chance can you make a tutorial about Haldor-Topsoe TREMP ?

@Chemiopedia 3 года назад

Can you share some details here: info@chemiopedia.com

@Lqtan16 Год назад

Hey Erkan, I am doing similar stuff too. Do you want to chat and discuss?

@KaranSharma-gn1nn 2 года назад

i tried to put these values in Aspen plus and followed the same steps you recommended in the previous (methanol) video but I am not getting any reaction the reactants are not reacting at all any idea why?

@KaranSharma-gn1nn 2 года назад

please help!!!

@lilhost5487 2 года назад

Информативно, очень помогло. Но можно сделать видео по моделированию LHHW в AspenPlus c паровой конверсией метана)

hi thanks, pls make video for another kinetic of reforming reaction ch4 + 2h2o ==> 4h2 + co2 im waiting for it .

@Chemiopedia 2 года назад

The SMR video, will be available soon including the above reaction. Don't forget to subscribe.

@umairhassankaust1939 2 года назад

Hi. I simulated the same process using the given parameters but the conversion is really really low (0.001%). I changed flow rate, temp, and pressure but observed no effect. Any idea why I am getting low conversion?

@manishmaurya6296 Год назад

Umair, did you find the reason for getting low conversion in SMR? Can you share it here?

@umairhassankaust1939 Год назад

@@manishmaurya6296 couldn't figure it out

@redagalih 11 месяцев назад

The k1 should be 1.17e+12 not e+15 and it would affect k1/K1 too

@rasheede.o4824 6 месяцев назад

Could you show the values for adsorption constant and driving force

@pepijnNLgod 2 месяца назад

@@rasheede.o4824 Yeah, I need the driving force ones too!

@@Chemiopedia hi I've been waiting since u told me, and i have another question. Is the kinetic of co in LTS & HTS different than the kinetic co in reformer?

@patriceamrolalaei6487 2 года назад

I check your article but u just discussed about the kinetics in reformer

@Chemiopedia 2 года назад

Sorry for delay. SMR process is basically a part of the next upcoming series of video. Due to some unforeseen circumstances, the series get delayed. You are requested to write us at support@chemiopedia.com. I will share the customized link of the SMR video with you. Remember, you will not allowed the share the content to anyone else.

@Chemiopedia 2 года назад

Kinetics of LTS and HTS will be different than the kinetics in the reformer as shift convertors utilizes different catalysts.
