Are there any solid oxide fuel cell (SOFC) testing facilities under payment basis?

I'm trying to use aspen to simulate the reactive distillation of butanol and acrylic acid to butyl acrylate using a RadFrac unit and LHHW kinetics. As pointed out by many other posts, RadFrac does not offer LHHW kinetics and I need to write a fortran subroutine in order to actually use LHHW kinetics for the kinetic expression I am utilizing. I have never used fortran before nor do I have experience with linking a subroutine to aspen. Does anyone have any resources they could point toward for actually accomplishing this? Thanks!

Good morning everyone,

I am trying to simulate the dissolution and re-precipitation process of EPS on Aspen Plus, but I have some difficulties to correctly define the polymer characteristics in order to get solid streams. As a matter of fact, all EPS streams that I try to define result being in the liquid phase, even at low temperatures. I think that this is due to the fact that the software cannot predict the melting temperature of the polymer, but I don’t know how to implement it since I already gave Aspen Plus the Van Krevelen structure of all the molecules involved, but it does not work.

Does someone know if Aspen Plus is able to predict the polymers behavior also in the solid phase? In case, which inputs should be given to the software?

Thanks in advance,

AP

I am modelling a heat pump and after the modelling part I am trying to use some refrigerant like L-41, and its not available in the EES library? Please share the knowledge if its possible to use and if yes then how can we add that refrigerant?

I can't simulation based on research. What should I do? The values obtained are not in accordance with the research. Can anyone help me simulate it or explain it? Please help.

I want to download a model for Urea synthesis loop. Preferably the Stamicarbon process. I found a PDF from AspenTech describing a model for this specific process but I would like to know if there is any way I can download an already simulated model instead of starting from scratch. Kindly advise.

Thank you.

I wanted to simulate article titled "Simulation of multi-method CO2 capture and purification process" using Aspen HYSYS software. However, I encountered a lack of data. If possible, could anyone please provide me with the complete data of the article?

Hello everyone. I'm trying to simulate distillation in a water-ethanol system. It's my goal to get >90% ethanol on distillation. With aspen hysys, it's easy to do, but with aspen plus, the data I earned from hysy doesn't work. Not only could I not use previous data for the right answer, but I also couldn't get to my goal in Aspen plus. Zf=0.22, T=22 centigrade, total condenser at 1 bar
