In many chemical processes, oxidation or partial oxidation reactions, oxygen rather than air is used as the oxidant. Typical examples are syngas production via partial oxidation, ethylene and ethylene-oxide production and oxy-combustion. However, oxidation reactions with oxygen enriched air is one of the most hazardous chemical processes for the significant increase of reactivity, for the enlargement of the flammability limits and for the likelihood of transition from deflagration to detonation. Recently, we found also that explosion of methane in oxygen enriched air may also lead to an anomalous explosion mode which has been named combustion induced rapid phase transition (cRPT)

Typical examples are syngas production via partial oxidation, ethylene and ethylene-oxide production and oxy-combustion. However, oxidation reactions with oxygen enriched air is one of the most hazardous chemical processes for the significant increase of reactivity, for the enlargement of the flammability limits and for the likelihood of transition from deflagration to detonation.
