What is adiabatic calorimetry?

Adiabatic calorimetry is used primarily for the study of thermal hazards and the consequences of a maloperation during a process, for instance a misfeed or loss of cooling. This is because on larger scales the effective natural cooling rates are negligible in comparison to heat generation, and many large process vessels can therefore be considered to be adiabatic.

An adiabatic calorimeter is designed to simulate the thermal behaviour of larger scale chemical reactors, especially when studying uncontrolled and run-away reactions.

A good example of adiabatic calorimeter is the Phi-TEC II (http://www.helgroup.com/home/reactor-systems/safety.html?subpage=7), manufactured by HEL Ltd.
