Exothermic heat release is fairly common during chemical synthesis and poses no real problem if it can be monitored and controlled. Regardless of how well the plant is designed, there remains a chance that something can go wrong and it is important to understand the consequences of this.
In this respect, HEL’s adiabatic calorimeters (Phi-TEC I and Phi-TEC II) and reaction calorimeter (SIMULAR) provide different ways in which to get an understanding of the worst case scenarios.
In effect, the SIMULAR reaction calorimeter allows the heat to be released in a controlled way. Since this heat amount is measured, it is possible to CALCULATE the potential temperature rise (Trise) if this were to be released uncontrollably – this being the worst case.
The Phi-TEC adiabatic calorimeters do the opposite they measure the temperature rise as heat is released uncontrollably. The worst case interms of temperature and pressure rise is what is measured – especially with Phi-TEC II.
Action in terms of design changes can then be based on the consequences demonstrated in the laboratory.
