Hi there everyone, I am working on a HYSYS simulation for GTL. I have modelled the Syngas generating unit of the simulation, but have been unable to do the Fischer tropsch synthesis part. The kinetic model I have for the Fischer tropsch reactions do not appear in any of the reaction types in the Hysys I am using. has anyone got an idea if it is possible to and how to create a user defined kinetic model and attach to a PFR reactor or any other reactor for that matter? I am also open to other suggestions on how to model the Fischer tropsch synthesis in HYSYS. Thanks
