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.
Hello, first of all thanks for making the Videos.but im confused about Why did you choose to set k and E as 1 and 0, instead of using k1 as the kinetic factor for LHHW? and simulation result of these two inputs are different
Hi, thanks for uploading this video I used this LHHW model with Rplug to adapt SMR process, but there isn't no reaction(convergence rate is zero). could i know what 's the problem?
i followed all the steps exactly like you did but the distillation column for me is taking very long time to run and at the end it is unconverged. I tried this 3,4 times but still same issue
the simulation does not converge because the specified bottom temperature (343.3°C) is the feed temperature and you place it at the bottom. The solution for the simulation to converge is by placing the column specification temperature in tray #37, for a temperature of (320°C) and eliminating the distillate velocity specification by the reflux ratio to 1.3
please Sir, when you design sale gas 2 for outlet of Balance it is not calculated at first but when you drag it to put it nearest of Balance it became dark blue, now when i design sale gas 2 it not solve, it is still the temperature and pressure, temperature of sales gas still unknown, but the balance item converged
Hello Thanks for your tutorial. I do the same as you show, but my absorber does not converge , it gives the error named : ' Fatal Error : Zero Diagonal in Column Matrix" , do you have any suggestions ? Thanks
I am doing the same steps as you but my run is not converging and it's step size is even 0.0001 instead of 1 while I do run can you please help me with this.
Hello! Your videos are very educational. Do you have any videos on using the Aspen Custom Modeler integrated with Aspen Plus for more complex kinetic considerations, such as Fischer-Tropsch?
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.
AoA sir! hope you are well sir I followed each and every step from beginning to end but my simulation failed to converge for the hydrocracker. any idea? can you help me with that plx
