    Find the Best Plant Configuration

     Use the flexibility of Sulsim to design fit-for-purpose plants by selecting the right SRU to meet demands. Consider multiple catalyst types and simulate various SRUs with 26 unit operations including furnace, reactors, incinerators, and more.


    New Sulsim Sulfur Recovery Modeling

    V9: New furnace models, catalysts, and SO2 absorber

    Familiar with Sulphur Expert’s Sulsim? Aspen HYSYS includes features not implemented in the most recently available Sulsim 7,  including incinerator kinetic correlations, the Titania catalyst model for a catalytic converter, five new empirical reaction furnace models, and an SO2 absorber model.


    Sulsim Degasser Sulfur Sulphur Recovery

    V10: New degasser model

    With the addition of the degasser model, Aspen HYSYS V10 can now model the solubility properties of H2S in liquid sulfur. The predicted concentration of the H2S content leaving the condenser is now available as part of the stream. The degasser model can report on liquid sulfur outlet density, thermal conductivity, viscosity, heat capacity, and surface tension
