CAPE-OPEN

Hello, Sorry, it´s been a while since these posts, but I always had this configuration in mind. I have set up a similar configuration also for an absorber I used for different type of process simulations, and it is working quite well. Kevin, I downloaded your original file but I could not open it pr...

Hello, I work in the field of carboxylic acids stripping from vegetable oils. Vapor association, as it was already said, it is one of the chemical explanations regarding why some compounds departure from vapor phase ideality, in case of carboxylic acids, can form dimers. But this is only significant...

OK, I understand.
Yes, thanks Jasper, that is what I had I mind to implement it.

Kind regards

Hi Jasper,

May be you already have this in your todo list, but is it feasible to run parametric studies with COFE embedded in the excel ?

Thanks in advance !!

I see. Well yes, I think you can do that simulation model easily at first using a fixed conversion reactor, some Measure Units, a controller and so on.

I do not know the process simulation context you want to use C elemental, but maybe you might use Graphite from Solids from COCO solids compounds library, since in nature it is carbon.

Yes, sorry, I meant the unit operation sort method. I thought it might have an impact in the resolution along the recycle. The evaluation of the embedded flowsheets does not take a long time, it is quite quick. What it takes too long, is each iteration to be solved and to get convergence. Generally,...

The recycle is in the outer flowsheet. The subflowsheets are Unit Ops (simple operations inside without recycle) that are located inside the outer recycle.
I tried to manually set up the sort method aiming to have positive impact in solving speed, but I did not get an apparent improvement.

Dear All, Is there a given set up in case of a model configuration having a recycle with multiple (5) sub-flowsheets ? The matter is that I am facing quite low solving time, each time when I run the simulation model either if I change mass composition at inlet streams or a temperature in a heat exch...

Hi Jasper, When using COFE_ObtainProperty formula, to get viscosity value from a given stream, the only way to get the appropriate value is by expressing the composition as fraction not as percent, either mass or mole. But this is not the case for other properties like density, heat capacity, enthal...
