Fast and highly exothermic reactions are commonly carried out in semibatch reactors (SBRs) in order to better control the heat evolution by the feeding rate. In fact, for such processes, a phenomenon known as “thermal runaway”, that is an uncontr

In the specific literature of the last seventy years, the problem of identifying the operating conditions (temperatures, pressures, concentrations, residence times, etc..) in correspondence of which, for different types of reactor and operating modes

In this paper a qualitative methodology for the initial assessment of flood-related Na-Tech risk was developed as a screening tool to identify which situations require a much more expensive quantitative risk analysis (QRA). Through the definition of

High concentrations of H2S in offshore wells represent a major concern for personnel safety: if a significant external H2S contamination occurs, depending on wells and process conditions, it may prove impossible an effective evacuation, and thus Temp

Dispersion of toxic and flammable materials from Chemical industries represents a major issue in Risk Analysis; presently, integral models are generally used to assess dispersion consequences, due to the low CPU and time requirements connected to the

Fire represents a very complex phenomenon, as the severity of the consequences associated with its evolution depends not only on the fire source itself, but also on the configuration of the system in which it develops, that is whether the source term

Thermal runaway in chemical batch and semibatch reactors is one of the major plagues in fine chemical, pharmaceutical and plastic industries. Quite often the root cause of such events is a poor knowledge of the process kinetics and thermodynamics. Fo
