   Types of Reactor models available in the simulators (Hysys Chemical Reactors).  Design a system for heat transfer in association with the reactor, to sustain an exothermic or endothermic reaction s at its desired temperature level.  Determine if a reactor network should be considered.   Process simulators offer four kinds of reactor models1.) a stochiometricmodel that permits the specification on reactant conversions and extents of reaction for one or more specified reactions2.) a model for multiple phases (vapor, liquid and solid) in chemical equilibrium3.) a kinetic model for a continuous-stirred – tank reactor (CSTR) that assumes perfect mixing of homogeneous phases (liquid or vapor).4.) a kinetic model for a plug-flow tubular reactor (PFTR or PFR), for homogeneous phases (liquid or vapor) and assuming no backmixing(dispersion). Early stages of process synthesis, reactor effluents and heat duties are needed.  For reactor models in simulators, it is necessary to provide R chemical reactions involving C chemical species: is the chemical formula for species j and is the stoichiometric coefficient for species j in reaction i negative for reactants, positive for products).
