Hello,
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, and if you have some advice to properly model the mixture.
Does Aspen have any 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 water saturated.
I would appreciate any help or advice/books concerning this topic,
Thanks a lot,
Nicolas
