Reactive Chemistry and Thermal Hazard Workshop
Reading calorimetry data and knowing what your process will do at plant scale
Runaway reactions remain among the most destructive process incidents and the most predictable from testing. This workshop covers the four characteristic temperatures, criticality classification, calorimetry interpretation including the thermal inertia correction, and what the data means for relief sizing and basis of safety.
This course sits alongside our Reactive Chemistry and Thermal Hazard consulting work, so what is taught is what we do.
Who should attend
Course content
Every module is taught with worked examples and exercises drawn from real plant, and adapted to your own process where the course runs in house.
Reaction hazard fundamentals
- Heat of reaction, adiabatic temperature rise and heat removal capacity
- Time to maximum rate under adiabatic conditions
- Desired reaction against secondary decomposition
- Accumulation in semi batch operation and why dosing control matters
The four characteristic temperatures
- Process temperature, maximum temperature of the synthesis reaction, maximum temperature for technical reasons and the temperature at which time to maximum rate is 24 hours
- Criticality classes 1 to 5 and what each demands of the design
- Using the classification to select a basis of safety
Calorimetry
- Screening by differential scanning calorimetry
- Reaction calorimetry for heat release rate and accumulation
- Adiabatic calorimetry for runaway characterisation
- Thermal inertia and correcting a measured result toward plant behaviour
- Specifying a test programme that answers the question you have
From data to design
- Basis of safety selection from temperature control through to relief and containment
- Vent sizing for vapour, gassy and hybrid systems
- Emergency cooling, quenching and reaction inhibition
- Incidents including T2 Laboratories and what the data would have shown
What you receive
- A calorimetry test specification template
- A criticality classification worksheet
- Worked adiabatic correction and vent sizing examples
- Assessment result and attendance record
What changes afterwards
- Reactive hazards get characterised before scale up rather than after an incident
- Calorimetry is commissioned to answer a specific design question
- Measured data is corrected toward plant scale rather than used raw
- Basis of safety is chosen deliberately and documented
