Where is the ratefrac module in Aspen?
Thread Content
I saw an example of an absorption tower solved using the Ratefrac module, and I’d like to ask the experts: where is the Ratefrac module in Aspen? I used the rate-based option in Radfrac, and it’s a bit different from the example given. I’d appreciate some advice from those who are more experienced!
In the Column module group, it is the second module from right to left. If your module disappears, press F10 to make it reappear
No, mine is version V7.0. Could it be a problem with the version?
It’s possible that Ratefrac in V7 has been assigned to another component; look carefully, or check the Help file for instructions
Quoting a reply from moderator zzuwangshilei: ratefrac is no longer available in Aspen 2006.5 and later versions. The calculation model of ratefract is based on flow rate balance, which differs from the traditional equilibrium-stage method. Starting with Aspen2006.5, radefrac already includes an option based on flow rate balance.
In the radfrac module, on the first page there is one that is set to balanced by default; click on it and you will see ratebased
The Rate-Based functionality in RadFrac within Aspen after 2006 is equivalent to RateFrac
