Hysys vs Aspen Plus
Hysys vs Aspen Plus
(OP)
It seems like the only advantage that Aspen Plus offers over Hysys is the ability to handle some (trace) solids...which is a negligible feature as far as I'm concerned. I heard that Hysys is better than Aspen Plus because Hysys does not truncate the binary coefficients. Therefore Hysys is much more accurate with the thermodynamic calculations.
I'm finding that the whole concept behind Aspen Plus is flawed for a user who just wants a simple interface with the program. It seems to be a program that is too complicated to use for people who aren't interested in spending weeks on end just to learn it's complex and redundant "quirks". It's a stupid program built by stupid people.

Measure it with a micrometer, mark it with a piece of chalk, then cut it with a chainsaw.....
I concur with paul1958

Next!
Can I get any decent tips here?

I laughed at first but they are as good as ...

Glenfiddich - really? With the same VLE method and parameters?

I can't use other software because the company I work for doesn't have them. Yes one company makes both but they have a different setup, as I mentioned before. Yes, the same EOS gives different results using the same assays, temperatures and pressures.

As we type here, the GPA is conducting a study on all the simulation packages. They will publish a list of strenghts and weaknesses. The report will refrain from declaring a winner.
I call BS on getting different results from the same input and EOS. Yeah, there might be a .5 psi difference in dew point presure or something like that, but nothing that is outside what your field devices can detect and repeat.
I had a kid make the same claim on how great brand x was. So I gave him a deethanizer that my brand y couldn't solve. He took the data and built up the tower. Btrand x couldn't solve it. He had bragged that brand x has terrific support, so I insisted that he use it. The tech had him raise the iteration to 1000 and told him it would take several minutes to solve.
Bottomline, it didn't solve. I then took over the keyboard and changed the feed temp and tray location. Then I showed him the output from my brand y with the same changes. Guess what, they had the same answer. Its not the software, its the user.
