  2. Fertilizer - Wikipedia

    en.wikipedia.org/wiki/Fertilizer

    Calcium ammonium nitrate Is a blend of 20-30% limestone CaCO 3 or dolomite (Ca,Mg)CO 3 and 70-80% ammonium nitrate with 24-28 % nitrogen. Calcium nitrate with 15,5% nitrogen and 19% calcium, reportedly holding a small share of the nitrogen fertilizer market (4% in 2007). [28] The main straight phosphate fertilizers are the superphosphates:

  3. UAN - Wikipedia

    en.wikipedia.org/wiki/UAN

    Other grades are UAN 28, UAN 30 and UAN 18. The solutions are quite corrosive towards mild steel (up to 0.5 inches (1.3 cm) per year on C1010 steel) and are therefore generally equipped with a corrosion inhibitor to protect tanks, pipelines, nozzles, etc. Urea–ammonium nitrate solutions should not be combined with calcium ammonium nitrate ...

    The active ingredients in the ODC cannabis line include the original chitosan ingredient at a concentration of 0.25%, as well as 0.28% colloidal nitrogen and 0.05% calcium. [ 25 ] [ 26 ] In order to enhance the resilience of hydroponic and aeroponic systems against plant diseases and reduce reliance on chemical additives, NASA explores the ...

  5. 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 ...

  6. 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 ...

  7. California Senate Bill 32 - Wikipedia

    en.wikipedia.org/wiki/California_Senate_Bill_32

    The California Global Warming Solutions Act of 2016: emissions limit, or SB-32, is a California Senate bill expanding upon AB-32 to reduce greenhouse gas (GHG) emissions. The lead author is Senator Fran Pavley and the principal co-author is Assemblymember Eduardo Garcia. SB-32 was signed into law on September 8, 2016, by Governor Jerry Brown. [1]

  8. Regulation of greenhouse gases under the Clean Air Act

    en.wikipedia.org/wiki/Regulation_of_greenhouse...

    Fifteen states have adopted California's standards. [45] Further, California and EPA have worked together so that the two programs converge and allow automakers to produce a single national fleet, which complies with both programs. [46] State regulations outside the Clean Air Act do affect emissions, especially gas tax rates.

  9. Waste-to-energy - Wikipedia

    en.wikipedia.org/wiki/Waste-to-energy

    Incineration, the combustion of organic material such as waste with energy recovery, is the most common WtE implementation. All new WtE plants in OECD countries incinerating waste (residual MSW, commercial, industrial or RDF) must meet strict emission standards, including those on nitrogen oxides (NO x), sulphur dioxide (SO 2), heavy metals and dioxins.
