  2. 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]

  3. Chlorine production - Wikipedia

    en.wikipedia.org/wiki/Chlorine_production

    The chlorine gas is compressed at this stage and may be further cooled by inter- and after-coolers. After compression it flows to the liquefiers, where it is cooled enough to liquefy. Non condensible gases and remaining chlorine gas are vented off as part of the pressure control of the liquefaction systems.

  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. Ultra-high-purity steam for oxidation and annealing - Wikipedia

    en.wikipedia.org/wiki/Ultra-high-purity_steam...

    The ideal water vapor for industrial manufacturing processes is extremely pure, moderate in temperature and free of extra oxygen or water microdroplets. In addition, this water vapor is ideally delivered in a range of flow rates from standard cubic centimeters per minute (sccm) to standard litre per minute (slm), into vacuum or atmosphere ...

  8. Potassium chlorate - Wikipedia

    en.wikipedia.org/wiki/Potassium_chlorate

    Since 2005, a cartridge with potassium chlorate mixed with lactose and rosin is used for generating the white smoke signaling the election of new pope by a papal conclave. [9] High school and college laboratories often use potassium chlorate to generate oxygen gas. [citation needed] It is a far cheaper source than a pressurized or cryogenic ...

  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 ...
