Abstract/Summary Modelling of a homogeneous continuous stirred tank reactor (CSTR) with a simple exothermic reaction for the computer-based HAZOP analysis is discussed. Using an appropriate mathematical model of CSTR, steady-state analysis (including analysis of multiplicity of steady states and their stability) and description of the dynamics behaviour of the reactor can be done. After generation of the parameter deviations in a chosen node, the steady-state solution diagram provides corresponding consequences of such failure. Dynamic simulation offers an answer to the time response of the reactor to the generated deviations. Moreover, it is possible to study also the influence of deviation duration on the reactor performance. Here, only one parameter, molar flow of the one of reactants, and its deviations from the normal operating point were investigated.
