    Graphite flakes can cost around US$0.9/kg carbon. [20] Price of synthetic industrial diamond for grinding and polishing can range from 1200 to 13 300 USD/kg, while cost per weight of large synthetic diamonds for industrial applications can be on the order of million dollars per kilogram.

  3. Nitrogen - Wikipedia

    en.wikipedia.org/wiki/Nitrogen

    Nitrogen gas is an industrial gas produced by the fractional distillation of liquid air, or by mechanical means using gaseous air (pressurised reverse osmosis membrane or pressure swing adsorption). Nitrogen gas generators using membranes or pressure swing adsorption (PSA) are typically more cost and energy efficient than bulk-delivered ...

    en.wikipedia.org/wiki/Natural_gas_prices

    Pipeline-quality gas has an energy value slightly higher than that of pure methane, which has 10.47 kilowatt-hours per cubic metre (1,012 British thermal units per cubic foot). Natural gas as it comes out of the ground is most often predominantly methane, but may have a wide range of energy values, from much lower (due to dilution by non ...

    The average cost of gas has decreased 15% in the last two years, from when it was $4.27 per gallon. The highest recorded average price of regular gas was in June 2022 at $5.06 per gallon.

  6. 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 ...

  7. Liquid nitrogen engine - Wikipedia

    en.wikipedia.org/wiki/Liquid_nitrogen_engine

    Since nitrogen is a colorless and odourless gas that already makes up 78 per cent of air, such a change would be difficult to detect. Cryogenic liquids are hazardous if spilled. Liquid nitrogen can cause frostbite and can make some materials extremely brittle. As liquid nitrogen is colder than 90.2K, oxygen from the atmosphere can condense.

    Nitrogen gas is used for a variety of purposes in manufacturing, welding, inflating tires and equipment calibration and maintenance. The plentiful supply is likely one reason that some states have ...

  9. 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 applications ...
