    Your video is really great, and I'm really looking forward to you releasing a video about step sequence design, such as the step sequence chart in a virtual tower

    Hello, Professor, Greetings... I would like to talk to you. I have many questions. What program would you prefer us to communicate with together?

    Hi, I've been following the steps in the video (using Aspen Adsorption V12.1) and I have checked several times that I do the exact same and the numbers are the exact same but when I hit the play button in the Initialization mode it says: "initialization failed at time 0." Then I click okay and it says "A sub-group in the decomposition failed to solve".
    I have then tried using the same numbers but with only NO3- present (removing PB+2 from the component list) and then it works. It is as if mine will not work with positive ions…
    Do you (or anyone reading this) know what could be the problem?
    And thanks for a nice video :)

      Check your feed and product stream properties and use Electrolyte NRTL property package. Hope it work. No need to remove Pb++

      Same thing happens to me, I don't know why cause I followed every step :(

      Thank you for answering :) I use ELECNRTL under Configure Properties (so base method is ELECNRTL in Aspen Properties) as shown in the video. Could the difference be that you might have changed something in Solver Options or something? Because everything I see in the video is the same in my script.
      In the Evaluation Messages it says: "Evaluation error in explicit group 617"

      @@vibekebrohansen3902 hello, I don't know if this can help you but I'm using Aspen V11 (the same version of the simulation from the article) and it works with just NRTL, the video is with Aspen V14 and the methods can change with different versions
