Oxygen is used to improve the yield of a large number of petrochemical
processes.
Oxygen can be used pure in chemical oxidation reactions such as the
production of ethylene oxide (EO), propylene oxide (PO), ethylene dichloride
(EDC), vinyl acetate monomer (VAM), titanium dioxide (TiO2), ferric sulfate
and also for the debottlenecking of air based processes such as those in the
production of acrylonitrile and purified terephtalic acid (PTA).
O2 is also used in the production of synthesis gas (H2/CO).
Mainly used for the glass melting and generally for all oxy-combustion
process.
As in the iron and steel industry (Decarburization of hot metal to produce
steel, and to enrich blast furnace air), oxygen is used in non ferrous
primary production, secondary smelting etc,With acetylene or LPGs, oxygen
allows to boost the flame properties in flame torches and burners (flame
temperature, specific flame output power).
