How to set the separation module sep in Aspen Plus?
Thread Content
May I ask how to set up the separation module SEP in Aspen Plus? Thank you!
The Sep module can accept multiple input streams, produce multiple output streams, and distribute the various components in the input mixture to each output stream according to specified ratios. And you should note that in the export logistics specifications, if you select \"split fraction\", its value indicates the proportion of a particular component within that selected stream relative to the amount of that component in the raw material.

But for example, if I want to separate hydrogen from syngas – which is a MIXED case – why does the value for the material in CIPSD also have to be set to 0? If that value isn’t set to zero, the system won’t operate. Why is that?
What is CIPSD? I don’t understand what it means……
It’s not yet clear what your process entails. The SEP module ignores the possibilities in terms of dynamics or thermodynamics associated with your requests; it simply delivers whatever amount of each component you request at each stream, as long as you adhere to the law of conservation of mass – namely, the same amount enters as exits.
You have set two logistics levels: MIX and CLSOLID. Naturally, each logistics level is relevant in this setup; and after the simulation, aren’t the logistics levels also divided into two parts? This has nothing to do with whether the specific module you have set contains inert materials
I want to know that too, haha :lol
6# zl128117 I would like to ask whether I can use this module to simulate multi-effect evaporation for seawater desalination with Aspen
Can pure substances be separated? Is the flow rate the same for each group?
Why not? But it should be noted that this module only satisfies the material balance; it doesn’t handle anything else. So it depends on the purpose of your simulation.
