Gases [ Return towards Environment]

O2 helps reduce NOx emisions (toxic) in glass and blast furnaces by partially replacing air. Oxygen is also used to recycle petroleum residues in order to produce energy and is involved in the manufacturing of new fuels. It participates in the recycling of different metals (Pb, Al).

Tires filling with nitrogen increases their lifetime and therefore decreases the recycling or treatment of this waste. In electronic packaging & assembly, Nitrogen is used in the lead-free processes.

CO2 can be used to suppress some kind offumes in the steel-making industry.

H2 is a carbon-free energy source used in the fuel cells. It is also used to desulfurize petroleumbased fuels.

It replaces chlorine in the bleaching of paper pulp and the washing of fresh fruit and vegetables.
When your waste water effluents need a good decolorization or "hard COD" reduction, think about ozone.
