PROCESS SAFETY GAME

RUNAWAY!

The cooling will fail. It always does, at the worst moment. Learn the Stoessel criticality diagram, then design four reactions, modelled on real reaction types, so that when the cooling goes, nothing else does.

STEP 1 · 3 MIN

Learn

ΔTad, MTSR, MTT, TD24 and the five criticality classes, with a diagram you can play with.

STEP 2 · 10 QUESTIONS

Quiz

Check what stuck. Every answer is explained.

STEP 3 · 4 REACTIONS

Challenge

Design the process, run the batch, survive the cooling failure. Earn up to 3 stars per reaction.

Choose a reaction

Teaching data, chosen to behave like these reaction types. Real processes need measured data (DSC, ARC, reaction calorimetry).
