  2. Liquid nitrogen - Wikipedia

    en.wikipedia.org/wiki/Liquid_nitrogen

    Liquid nitrogen is a compact and readily transported source of dry nitrogen gas, as it does not require pressurization. Further, its ability to maintain temperatures far below the freezing point of water, specific heat of 1040 J ⋅kg −1 ⋅K −1 and heat of vaporization of 200 kJ⋅kg −1 makes it extremely useful in a wide range of ...

  3. Charcoal - Wikipedia

    en.wikipedia.org/wiki/Charcoal

    Charcoal burning Grill charcoal made from coconut shell. Charcoal has been used since earliest times for a large range of purposes including art and medicine, but by far its most important use has been as a metallurgical fuel. Charcoal is the traditional fuel of a blacksmith's forge and other applications where an intense heat is required.

  4. Top-lit updraft gasifier - Wikipedia

    en.wikipedia.org/wiki/Top-lit_updraft_gasifier

    A top-lit updraft gasifier (also known as a TLUD) is a micro-kiln used to produce charcoal, especially biochar, and heat for cooking. [1] A TLUD pyrolyzes organic material, including wood or manure, and uses a reburner to eliminate volatile byproducts of pyrolization.

  5. Nitrogen generator - Wikipedia

    en.wikipedia.org/wiki/Nitrogen_generator

    Aircraft tires use nitrogen fill to delay tire rupture on rejected take off events, allowing evacuation time before brake system heat causes an internal tire fire. Fusible plugs in the tire are the primary protection against heat induced pressure excursion. Internal tire fires can kindle at initial stop due to local hot sections of the wheels.

  6. Liquefaction of gases - Wikipedia

    en.wikipedia.org/wiki/Liquefaction_of_gases

    Liquid nitrogen Liquefaction of gases is physical conversion of a gas into a liquid state ( condensation ). The liquefaction of gases is a complicated process that uses various compressions and expansions to achieve high pressures and very low temperatures, using, for example, turboexpanders .

  7. Wood gas - Wikipedia

    en.wikipedia.org/wiki/Wood_gas

    Steam-gasification processes typically yield high hydrogen contents, downdraft fixed bed gasifiers yield high nitrogen concentrations and low tar loads, while updraft fixed bed gasifiers yield high tar loads. [6] [8] During the production of charcoal for blackpowder, the volatile wood gas is vented. Extremely-high-surface-area carbon results ...

    Alabama is seeking to become the first state to execute a prisoner by making him breathe pure nitrogen. The Alabama attorney general’s office on Friday asked the state Supreme Court to set an ...

  9. Cryogenic gas plant - Wikipedia

    en.wikipedia.org/wiki/Cryogenic_gas_plant

    A cryogenic gas plant is an industrial facility that creates molecular oxygen, molecular nitrogen, argon, krypton, helium, and xenon at relatively high purity. [1] As air is made up of nitrogen, the most common gas in the atmosphere, at 78%, with oxygen at 19%, and argon at 1%, with trace gasses making up the rest, cryogenic gas plants separate air inside a distillation column at cryogenic ...
