Abstract: Interest in discovering multiple steady-state solutions for reaction processes grew exponentially by the existence of the first computers. Modern process simulators can find multiple solutions only by the expenditure of much effort. Three mathematical models with different accuracy are introduced and a simple comparison of model's accuracy is made with regard to safety analysis of continuous stirred tank reactor. The first two models are based on standards in chemical reactor design; the third one is an internal model of CSTR in HYSYS simulation program. Furthermore, OLE automation interface is also used to access the existing physical property packages of HYSYS.
