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
