Hello everybody,
I am trying to model a gas cleaning section in DWSim. Attached you can find the file. When I have in the settings very common components (CO2, CO, H2, CH4 -out of which my gas is made of-), I face no issue. But I face these problems:

  1. I want to add a methanol scrubbing unit. Then I add methanol as compound in the settings and I get the error "Syngas-5: Error Index was outside the bounds of the array". However, I set 0 Methanol content in the stream "Syngas-5". Can you give me a hint on how to solve this?
  2. I tried to add other components (acetylene, ethane, toluene, phenol) in my input syngas. By leaving the thermodynamic settings as they are I get also the same error notification as above. I changed the solver to Gibbs which works, but it was really slow exceeding the maximum time for calculation. I tried other thermodynamic models but I face other issues like missing property parameters. Do you have maybe some hints on how to solve this case too?
    Really thanks in advance,
    Pietro
