Hello,
I am sorry for those who already have seen my post on "AspenTech Forum". As I guess there may be no "clear" answer for direct Hysys modelling, I try to extend the scope of my question.
I'am currently working on the design of a TSA (temperature swing adsorption) unit and trying to model the phase behaviour of a natural gas enriched with THT (tetrahydrotiophene or Thiophane, C4H8S, cyclic) in Hysys, a usual natural gas odorant) and BTEX components. I am using Hysys to model the unit.
But, in the Fluid Package I have tried (classical EOS: PR, SRK, TwuSim Tassone of which I have read it may be the most accurate for the mixture), there are no interaction parameters for THT and other hydrocarbons. I guess there is some patch or package to install which could allow me to work with these components, but I don't know which one.
I would like to know where I could search this kind of data to complete the Hysys Fluid Packages "by hand", and if you have some advice to properly model the mixture.
Where could I find a database concerning these kinds of mixture and their phase behaviour, or some recommendations about thermodynamics packages/EOS I could use to properly model them ?
To make my demand more precise, the content of the enriched gas is in the order of 1000-2000 ppm of THT, same for BTEX compound and it is water saturated.
I would appreciate any help or advice/books concerning this topic,
Thanks a lot,
Nicolas
