How to use Aspen to design complex extractive distillation columns?
Thread Content
My graduation thesis requires the design of the main equipment for the separation of C5 fractions. It is necessary to design heat-dimerization reactors as well as extraction distillation columns, etc. But I’m unfamiliar with Aspen and don’t know where to start, so could anyone give me some advice?
If it’s about reactor design, it is recommended to use Aspen Plus for preliminary simulations first to determine the approximate specifications; thereafter, CFD simulations can be used. Only by calculating the spatial distribution of fluid dynamics parameters can the reactor design be optimized. For extraction processes, Aspen Plus’ RadFrac module can be utilized, as it involves strict steady-state calculations. In fact, the principle of extraction distillation has little to do with the design of towers, since extraction relies mainly on differences in the distribution ratios of components. This means that accurate binary interaction parameters are necessary, so it’s best to have property data obtained under your actual experimental conditions, so that the simulations can better match the experimental results. Generally, the accuracy of Aspen Plus’ built-in database is quite good, but that’s not the case when estimating material properties for design purposes. If you need further assistance, feel free to share the specific details of your design challenge with me; you can also send an email to *aohaiyi8080@yahoo.com.cn*. Let’s learn together and improve together! Desperate to get extra points! I’ll reach grade 3 soon, and I have a lot of materials to share with everyone
I am very grateful for your help. I will write to you for advice when the time is right. :)
What is the binary interaction parameter? I still don’t know yet; I’m going to need extractive distillation soon
Is there a enthalpy for the dimerization reaction, OP? ? ?
