  2. Chlorine production - Wikipedia

    en.wikipedia.org/wiki/Chlorine_production

    Chlorine gas exiting the cell line must be cooled and dried since the exit gas can be over 80°C and contains moisture that allows chlorine gas to be corrosive to iron piping. Cooling the gas allows for a large amount of moisture from the brine to condense out of the gas stream.

  3. Oxychlorination - Wikipedia

    en.wikipedia.org/wiki/Oxychlorination

    In chemistry, oxychlorination is a process for generating the equivalent of chlorine gas (Cl 2) from hydrogen chloride and oxygen. [1] This process is attractive industrially because hydrogen chloride is less expensive than chlorine. [2]

  4. Chloralkali process - Wikipedia

    en.wikipedia.org/wiki/Chloralkali_process

    The chloralkali process (also chlor-alkali and chlor alkali) is an industrial process for the electrolysis of sodium chloride (NaCl) solutions. It is the technology used to produce chlorine and sodium hydroxide (caustic soda), [ 1 ] which are commodity chemicals required by industry.

  5. Chemical oxygen generator - Wikipedia

    en.wikipedia.org/wiki/Chemical_oxygen_generator

    A chlorate candle, or an oxygen candle, is a cylindrical chemical oxygen generator that contains a mix of sodium chlorate and iron powder, which when ignited smolders at about 600 °C (1,100 °F), producing sodium chloride, iron oxide, and oxygen at a fixed rate of about 6.5 man-hours per kilogram of the mixture. The mixture has an indefinite ...

  6. Industrial gas - Wikipedia

    en.wikipedia.org/wiki/Industrial_gas

    A gas regulator attached to a nitrogen cylinder. Industrial gases are the gaseous materials that are manufactured for use in industry.The principal gases provided are nitrogen, oxygen, carbon dioxide, argon, hydrogen, helium and acetylene, although many other gases and mixtures are also available in gas cylinders.

  7. Wacker process - Wikipedia

    en.wikipedia.org/wiki/Wacker_process

    Catalyst solution containing acetaldehyde is separated by flash distillation. The catalyst is oxidized in the oxidation reactor at 1000 kPa using air as oxidizing medium. Oxidized catalyst solution is separated and sent back to reactor. Oxygen from air is used up completely and the exhaust air is circulated as inert gas.

  8. Chloride process - Wikipedia

    en.wikipedia.org/wiki/Chloride_process

    The oxidized form of the chlorine is molecular chlorine Cl 2, the reduced form is titanium tetrachloride (TiCl 4). The oxidizing agent is molecular oxygen (O 2), the reducing agent is coke. Both must be fed into the process. The titanium is fed into the process in form of ore together with the coke. Titanium ore is a mixture of oxides.

  9. Chlorine - Wikipedia

    en.wikipedia.org/wiki/Chlorine

    Although aqua regia is an unstable mixture that continually gives off fumes containing free chlorine gas, this chlorine gas appears to have been ignored until c. 1630, when its nature as a separate gaseous substance was recognised by the Brabantian chemist and physician Jan Baptist van Helmont. [15] [en 1] Carl Wilhelm Scheele, discoverer of ...
