Worst-Case Scenario

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 AdiabaticAdiabatic 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.
