Related to a chemical reactor, a worst-case scenario is the situation where temperature and/or pressure production caused by the reaction runs out of control.
The heat and/or pressure the reaction produces cannot be reduced or controlled properly. If the heat of reaction is not compensated by a cooling device, the heat remains inside the reactor which is then AdiabaticoAdiabatic describes a system or measurement mode without any heat exchange with the surroundings. This mode can be realized using a calorimeter device according to the method of accelerating rate calorimetry (ARC). The main purpose of such a device is to study scenarios and thermal runaway reactions. A short description of the adiabatic mode is “no heat in – no heat out”.adiabatic. Inside an adiabatic reactor, the increasing temperature is furthermore accelerating the reaction. This scenario can lead to a Thermal runawayA thermal runaway is the situation where a chemical reactor is out of control with respect to temperature and/or pressure production caused by the chemical reaction itself. Simulation of a thermal runaway is usually carried out using a calorimeter device according to accelerated rate calorimetry (ARC).thermal runaway and finally in an explosion or another hazardous scenario. Simulation of a worst-case scenario is usually carried out using a calorimeter device according to accelerated rate calorimetry (Calorimetria Adiabatica di Reazione (ARC)The method describing isothermal and adiabatic test procedures used to detect thermally exothermic decomposition reactions.ARC®).
