Pure hydrogen is used for the production of plastics, polyester and nylon. H2 gas is also used in the hydrogenation of amines and fatty acids (food oils).
Glass, Cement and Lime
Hydrogen is an active gas used in combination with nitrogen to create a reductive atmosphere over the tin bath in the FLOAT glass process.
Hydrogen is also used for heat treatment (oxy-hydrogen flame) of the hollow glass and the optic fibers pre-forms.
Hydrogen is responsible for the generation of reductive atmosphere for various processes of heat treatment.
Laboratories & analysis
Hydrogen is used as a carrier gas in gas chromatography and in various analytical instrument applications, most commonly as a fuel component of combustion gases for Flame Ionization (FID) and Flame Photometric (FPD) detectors. Spark discharge analyzers, total hydrocarbons measurements use also hydrogen mixtures.
Welding, Cutting & Coating
Heat treatment of various metals.
Oil and Gas Industry
Desulfurization of fuel-oil and gasoline.
Hydrogen is used as carrier gas in semiconductor processes, especially for silicon deposition or crystal growing and as a scavenger gas in atmosphere soldering as well as for annealing copper films. The use of forming gases (that is H2 diluted in nitrogen) allows virtually a complete elimination of oxygen and its inconveniences in medium to high temperature processes.
Automotive & transportation
Hydrogen is a carbon-free energy source used in the fuel cells.
