GAS APPLICATION
Increased oxygen content can decisively improve the efficiency of oxidation reactions. The use of oxygen has the following advantages compared to pure air operation:
- Increase in selectivity and product yield
 - Possible capacity increase
 - Lower costs for product processing
 - Greater flexibility in operation
 
MESSER SOLUTION
Pure oxygen can be used in a particularly efficient way for gas/liquid reactions. In addition to the optimal feed system, other factors, in which Messer can provide sound expert knowledge, also play a decisive role.
Applications for oxygen- or oxygen-enriched air already exist in the following industrially used processes, or they are in the development phase:
- Terephthalic acid (PTA) and isophthalic acid (IPA) from p-xylene und m-xylene
 - Acetone and phenol from benzene and isopropylene via the Cumene-Hydroperoxide-Process
 - Styrene and propylene oxide from benzene and ethylene via ethylbenzene-hydroperoxide (Halcon-Process)
 - Cyclohexanone/Cyclohexanol (KA oil) from cyclohexane
 - Benzoic acid from toluene
 - Hydrogen peroxide via the Anthraquinone process
