Ozonolysis Plant

0.48 Kg/Hr
Process The Ozonolysis Plant Was Designed To Produce Azelaic
And Pelargonic Acids From Oleic Acid.
It Also Could Be Used For Ozonolysis Of Other Unsaturated Materials Like Vegetable Oils.
A Mixture Of Ozone (6-15%), Nitrogen (1%) And Oxygen (84-91%)
Is Reacted With Oleic Acid (Or Vegetable Oils) In A Coiled Steel Reactor.
The Ozone Cleaves The Double Bonds In The Unsaturated Acid
To Produce An Oil Of Altered Structure.
The Reaction Is Exothermic And Should Proceed At A Temperature Of 20-50 Celsius.
A Mixture Of Gas And Oils Leaves The Reactor And Is Separated
In A Water Cooled Separator.
The Gases Go To Waste Whilst About 10% Of The Oil Is Drained Off
As Product And The Rest Recycled Back Into The Reactor.
A Second Process (Oxidation Of Peroxides From First Process)
May Be Used In Which The Ozonised Oil Is Further Reacted
With Oxygen In Another Coiled Steel Reactor Immersed In
An Oil Bath At Approximately 120 Celsius.
Oil And Gas Are Then Separated In A Water Cooled Separator
Before The Oil Is Finally Stored At Around 50-60 Celsius.
The Oxygen Supply Will Be Piped To The Ozone Generators
In Non Welded Pipes At A Pressure Of Approximately 8 Bar.
The Ozone Will Be Supplied To The Reactor At A Pressure Not Exceeding 1.25 Bar.
The End Products Are Azelaic And Pelargonic Acids Ozonolysis Plant
Mainly Consists Of Two Ozonia Cfs7 Ozone Generators
(Operated Individually Or In Parallel,
Maximum Flow Rate 0.48 Kg/H Ozone Per Generator,
At 6% O3, Operating Output Estimated At 0.16 Kg/H O3 Per Generator,
At 14% Ozone Concentration, Oxygen Consumption 5.4 M³/H At 6% O3 Output,
2.5 M³/H At 10% O3 Output) Ozonolysis Loop Reactor
(The Loop Reactor Consists Of A Pumped Circuit Constructed
In Small-Bore Stainless Steel Tubing. An Oxygen /
Ozone Mixture Is Injected Downstream Of The Circulation Pump P304,
And Unreacted Gas Is Removed From The Circuit Using
A Cyclonic Separator / Expansion Tube. N01/P304
(Reactor Loop Pump) Is A Variable Speed, Inverter Driven,
Gear Type Metering Pump
