Chlorine can be manufactured by the electrolysis of a sodium chloride solution (), which is known as the Chloralkali process.The production of chlorine results in the co-products caustic soda (sodium hydroxide, NaOH) and hydrogen gas (H 2).
Related processes are known that use molten NaCl to give chlorine and sodium metal or condensed hydrogen chloride to give hydrogen and chlorine. The process has a high energy consumption, for example around 2,500 kWh (9,000 MJ) of electricity per tonne of sodium hydroxide produced.
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.
The process was based on the oxidation of hydrogen chloride: 4 HCl + O 2 → 2 Cl 2 + 2H 2 O. The reaction takes place at about 400 to 450 °C in the presence of a variety of catalysts, including copper chloride (CuCl 2). Three companies developed commercial processes for producing chlorine based on the Deacon reaction: [1]
In industry, elemental chlorine is usually produced by the electrolysis of sodium chloride dissolved in water. This method, the chloralkali process industrialized in 1892, now provides most industrial chlorine gas. [32] Along with chlorine, the method yields hydrogen gas and sodium hydroxide, which is the most valuable
Shelter-in-place recommendations and evacuation orders have been lifted Monday after a fire at a Georgia industrial plant caused a chemical reaction that prompted around 17,000 people to evacuate ...
Hydrogen gas is produced by several industrial methods. [1] Nearly all of the world's current supply of hydrogen is created from fossil fuels. [2] [3] Most hydrogen is gray hydrogen made through steam methane reforming. In this process, hydrogen is produced from a chemical reaction between steam and methane, the main component of natural gas.
The chemical fire sent chlorine into the air, ... the chlorine smoke closed schools and led to a shelter-in-place order for more than 90,000 residents east of Atlanta while some were told to ...
