How Are Common Gases Industrially Prepared?

[danago]

Hi. I am working on an assignment involving common gases (oxygen, nitrogen, ammonia etc.). I've done it all, except for the 'Industrial preparation' of the gases. What is industrial preparation? i know what laboratory preparation is, but not industrial.

Thanks,
Dan.

Industrial preparation refers to the processes used in industry (large scale) for preparation of the gases. Since air is mostly nitrogen and oxygen, large plants are devoted to process air into its components. Since gases liquify at different temperatures, 'liquefaction' is used so condense (liquify) and separate the various gases.

Other producers are Linde, Praxair, Air Liquide, Air Products.

Ammonia is chemically produced from N₂ and H₂. The Haber process is used. http://en.wikipedia.org/wiki/Haber-Bosch

Hydrogen is a by-product of petroleum, or it can be produced by radiolysis of water, or chemically by reaction of carbides with water, which are more expensive.

Industrial preparation of gases refers to the processes and methods used to produce large quantities of gases for commercial and industrial use. This can involve various techniques such as chemical reactions, separation processes, and purification methods.

For example, oxygen can be industrially prepared through the process of fractional distillation of air. This involves cooling and compressing air to separate the various components, with oxygen being the second most abundant gas after nitrogen. Ammonia, on the other hand, is commonly produced through the Haber-Bosch process, which involves reacting nitrogen and hydrogen under high pressure and temperature.

Industrial preparation of gases is important for meeting the demand for these gases in various industries such as manufacturing, healthcare, and energy production. It also involves ensuring the purity and quality of the gases for their intended use.

I hope this helps clarify the concept of industrial preparation of gases. Good luck with your assignment!
