Gas Solubility calculations with Aspen Plus
Gas Solubility calculations with Aspen Plus
(OP)
I am running a simulation with Aspen Plus to study gas solubility in alcohols, the gas feed is compose by H2 O2 N2, the operation conditions are P= 90-150 bar (high pressure) and low temperatures (30-70 ÂșC). I would like to know what property method of those available in Aspen could calculate the gas solubility in alcohol more accurate, because I have tried with several of then (PRWS, RKSMHV2, RKSWS, PSRK, RKSMHV2) and there are big differences between then.
Thanks
Thanks

Your key info may be the Henry's Law data for your system. I'm not sure if that would vary between the thermodynamic methods you mentioned but how the different methods use that data could vary.
As previously mentioned, it would be a good idea to validate your simulations against either lab data or actual operating data.

Can you provide some details about what you are trying to model? I modelled the degassing of hydrogen from alcohol in atmospheric storage tanks for my previous employer and found that hydrogen will accumulate and form an flammable mixture. Also I know of a plant in Italy a few years ago that had an explosion and fatality because of degassing in the storage tank.
