  2. Carbon dioxide scrubber - Wikipedia

    en.wikipedia.org/wiki/Carbon_dioxide_scrubber

    A carbon dioxide scrubber. A carbon dioxide scrubber is a piece of equipment that absorbs carbon dioxide (CO 2).It is used to treat exhaust gases from industrial plants or from exhaled air in life support systems such as rebreathers or in spacecraft, submersible craft or airtight chambers.

  3. Gas blending - Wikipedia

    en.wikipedia.org/wiki/Gas_blending

    Gas blending is the process of mixing gases for a specific purpose where the composition of the resulting mixture is defined, and therefore, controlled. A wide range of applications include scientific and industrial processes, food production and storage and breathing gases.

  4. Environmental impact of concrete - Wikipedia

    en.wikipedia.org/wiki/Environmental_impact_of...

    The environmental impact of concrete, its manufacture, and its applications, are complex, driven in part by direct impacts of construction and infrastructure, as well as by CO 2 emissions; between 4-8% of total global CO 2 emissions come from concrete. [1]

  5. Gas blending for scuba diving - Wikipedia

    en.wikipedia.org/wiki/Gas_blending_for_scuba_diving

    However, all of the nitrogen is provided by the air top-up, so the partial pressure of the nitrogen is calculated in a similar way as for helium, which allows the pressure of the air to be calculated, assuming nitrogen to be 79% of the air. In the Tx 20/40 example, the fraction of nitrogen is 100% - (20% + 40%) = 40%.

  6. Selective catalytic reduction - Wikipedia

    en.wikipedia.org/wiki/Selective_catalytic_reduction

    Selective catalytic reduction (SCR) means converting nitrogen oxides, also referred to as NO x with the aid of a catalyst into diatomic nitrogen (N 2), and water (H 2 O). A reductant, typically anhydrous ammonia (NH 3), aqueous ammonia (NH 4 OH), or a urea (CO(NH 2) 2) solution, is added to a stream of flue or exhaust gas and is reacted onto a ...

  7. Static mixer - Wikipedia

    en.wikipedia.org/wiki/Static_mixer

    A static mixer is a device for the continuous mixing of fluid materials, without moving components. [1] Normally the fluids to be mixed are liquid, but static mixers can also be used to mix gas streams, disperse gas into liquid or blend immiscible liquids .

  8. Nitrox - Wikipedia

    en.wikipedia.org/wiki/Nitrox

    The most common use of nitrox mixtures containing oxygen in higher proportions than atmospheric air is in scuba diving, where the reduced partial pressure of nitrogen is advantageous in reducing nitrogen uptake in the body's tissues, thereby extending the practicable underwater dive time by reducing the decompression requirement, or reducing ...
