Ozone Half-LIfe

Typical Ozone Half Life Time as a Function of Temperature:

Gaseous Ozone

     Dissolved in Water (pH 7)

Half LIfe Time

 Temperature   Half Life Time Temperature
3-months -50-deg C   30 Minutes 15-deg C
18-days -35-deg C                        20 Minutes 20-deg C
8-days -25-deg C   15 Minutes 25-deg C
3-days 20-deg C   12 Minutes 30-deg C
1.5-hours 120-deg C   8 Minutes 35-deg C
1.5-seconds 250-deg C      

 

These values are based on thermal composition, no wall effects or other catalytic effects are considered

Actual half life of ozone will be much, much lower when organic loading is involved along with pressure, humidity, and other factors.  These values give a good indication as to how quickly ozone decomposes, and also, how large a factor temperature plays in ozone half-life.

Temperature can play both positive and negative effects on ozone applications.  When temperature are very low, ozone half-life is very long, however ozone is much more stable and may not react as quickly as desired.  In contrast, when temperatures are very high, ozone half-life may be so so short that there is no time for ozone to be effective, or ozone reaction rates may be sped up sufficiently to create the desired reaction in less time.  When working with ozone ALWAYS remember to keep temperature in mind.
