When we are simulate the PFR, the isothermic calculation is not calculated and when click on the solve button this gives error in simulating the PFR.
sir, I put every value as per instruction but still there is error showing. the file link:-https://drive.google.com/file/d/16Ph3BOIENzjA3aBr17sjCjUiXfqaJ6K0/view?usp=drive_link
Not getting conversion rates as per tutorial, my getting 0.02 and 0.06 for nitrogen and hydrogen resp. Tried changing units of velocity, still answer remains same. pl help
even though following all the steps I am getting conversion low, NITROGEN = 0.0193 and HYDROGEN = 0.058.Please tell me where I did mistake, I am using DWSIM version 6.6Below I attached the file of nitrogen and hydrogen in PFD.https://drive.google.com/file/d/1Ge6rEbGm9jEZv88cRkONVA4Dc3E4aRqr/view?usp=sharing
sir, i have followed all the steps as it is in the tutorial but conversion of N getting +200 and H getting +300.
I am trying to simulate Dibenzyl toluene -Hydrogen reaction in the DWSim using PFR, when the reactor is kept at isothermal conditions , it calculates and does not show any error and when the reactor is switch through adiabatic , it shows the following error such as PFR 01-Phase equilibria calculation error
in results section there's no conversion appearing after solving the flowsheet
How to decide the the minimum and maximum temperature since the stream temperature is 425 degrees celcius? Is it an assumption or a particular standard to be followed in such case?
In the tutorial, the conversion of Nitrogen is 17.91% and conversion of Hydrogen is 53.73%.While simulating, I am getting the conversion of Nitrogen as 0.02 and conversion of Hydrogen to be 0.06.
the flash algorithm, not appearing dwsimthe flash algorithm property not appearing on dwsim while starting a new steady-state simulation window.
the flash algorithm property not appearing on dwsim while starting a new steady-state simulation window.
For Nitrogen, the conversion is 17.91% and for Hydrogen, it is 53.73%.On my interface it is 19.5965% and 58.7896% respectively. I am using DWSIM Version 6.1 Update 1.
I am unable to find "New Steady-state simulation" option under File Menu as displayed in the tutorial. I am using DWSIM Version 6.1 Update 1.
I cannot find the Unit Operations tab from where I can drag and drop Plug Flow Reactor. I am using DWSIM Version 6.1 Update 1.
In the Direct Reaction, there are two options as Arrehenius and User-Defined. For which should A=0.004 be entered? I am using DWSIM Version 6.1 Update 1
I am unable to find any green tick button to Accept changes.I am using DWSIM Version 6.1 Update 1.
I am unable to locate the Composition option to enter the Basis as Mole Fraction.I am using DWSIM Version 6.1 Update 1.
I am unable to locate the Object Palette window on the right-hand side of the main simulation window. I am using DWSIM Version 6.1 Update 1.
I wish to know in the assignment problem, how we decide DO values for individual reactants (I took DO=1 for Ethylene Glycol and zero for others- please let me know it is decided). Also I wish to know how to decide Tmin and Tmax values (When I took Tmin= 300K as I read that 333K is the desired temp, I got 100+ values of Conversions ).Also, the type of reactor was not specified (Adiabatic or Isothermal). Has these things omitted for us to research about them through papers?
Please tell us what are the chemical reaction kinetics specifications we need to put in the settings menu? after giving some appropriate specifications on researching , the flow sheet is giving pressure drop error inside PFR! Please help? Thanks, with regards.
After starting simulation configuration Wizard window, it doesnot show flash algoritham.I have downloaded 5.8 version is it requires 4.3 kindly guide
I am getting an error message as ' The pressure drop inside the PFR is too high. Check input data like volume, diameter and catalyst loading, if applicable. Can you pl help on this error?Thank you in advance.
Hi,I can't find the "REACTIONS MANAGER" under Tools \r\ntoolbar. Is it because my DWSIM version is not enough to simulate such \r\nreactions?Many thanks.ISIK
We are given the value of k, but you put it on the space for value of A, the frequency factor. Where do we put the value of k? Also where do we put the units of k, as in the assignment the units of k = 1/seconds and on the tutorial k was unit-less. You also left velocity units empty.l assume velocity unit = reaction rate units and amount unit = molar concentration units. Your help will be much appreciated. Thanks
I was trying to simulate a PFR for the production of aniline from nitrobenzene. I got an error message that states "PFR-010-Phase equilibria calculation error".Do you have any suggestions how I can go about fixing it?. I tried changing the PFR parameters but it still doesnt work.Thanking you in advance
